摘要 In a vehicle, a left shock absorber is disposed such that a left telescopic axis is positioned on the left of a left steering axis in a left-right direction of a body frame when a vehicle in which the body frame is standing upright is viewed from a front in a front-rear direction of the body frame. A right shock absorber is disposed such that a right telescopic axis is positioned on the right of a right steering axis in the left-right direction of the body frame when the vehicle in which the body frame is standing upright is viewed from the front in the front-rear direction of the body frame.

主权项 1. A vehicle comprising: a body frame; a left front wheel and a right front wheel that are arranged side by side in a left-right direction of the body frame; a linkage disposed above the left front wheel and the right front wheel in an up-down direction of the body frame, and that changes positions of the left front wheel and the right front wheel relative to the body frame to cause the body frame to lean to the left or to the right of the vehicle; a left telescopic suspension that supports the left front wheel and attenuates or absorbs a displacement of the left front wheel toward the linkage in the up-down direction of the body frame; and a right telescopic suspension that supports the right front wheel and attenuates or absorbs a displacement of the right front wheel toward the linkage in the up-down direction of the body frame; wherein the linkage includes: an upper cross member;a lower cross member disposed below the upper cross member in the up-down direction of the body frame;a left side member disposed above the left front wheel in the up-down direction of the body frame and that supports the left telescopic suspension such that the left telescopic suspension is able to turn about a left steering axis extending in the up-down direction of the body frame;a right side member disposed above the right front wheel in the up-down direction of the body frame and that supports the right telescopic suspension such that the right telescopic suspension is able to turn about a right steering axis extending in the up-down direction of the body frame; whereinthe upper cross member, the lower cross member, the left side member, and the right side member are connected such that the upper cross member and the lower cross member maintain postures that are parallel to each other, and such that the left side member and the right side member maintain postures that are parallel to each other; the left telescopic suspension includes: a left shock absorber including a left inner portion and a left outer portion that are movable relative to each other along a left telescopic axis extending in the up-down direction of the body frame; anda left turn restrictor including a left guide portion and a left guided portion that are movable relative to each other in a direction parallel to the left telescopic axis and that restrict relative turning of the left inner portion and the left outer portion; whereinone of the left inner portion and the left outer portion supports the left front wheel;the other one of the left inner portion and the left outer portion is supported by the left side member;one of the left guide portion and the left guided portion is connected to the left inner portion;the other one of the left guide portion and the left guided portion is connected to the left outer portion; the right telescopic suspension includes: a right shock absorber including a right inner portion and a right outer portion that are movable relative to each other along a right telescopic axis extending in the up-down direction of the body frame; anda right turn restrictor including a right guide portion and a right guided portion that are movable relative to each other in a direction parallel to the right telescopic axis and that restrict relative turning of the right inner portion and the right outer portion; whereinone of the right inner portion and the right outer portion supports the right front wheel;the other one of the right inner portion and the right outer portion is supported by the right side member;one of the right guide portion and the right guided portion is connected to the right inner portion;the other one of the right guide portion and the right guided portion is connected to the right outer portion; a distance between the left steering axis and a left end of the lower cross member in the left-right direction of the body frame is shorter than a distance between the left steering axis and the right steering axis in the left-right direction of the body frame when the vehicle in which the body frame is standing upright is viewed from a front in a front-rear direction of the body frame; a distance between the right steering axis and a right end of the lower cross member in the right-right direction of the body frame is shorter than a distance between the left steering axis and the right steering axis in the right-right direction of the body frame when the vehicle in which the body frame is standing upright is viewed from the front in the front-rear direction of the body frame; the left shock absorber is disposed such that the left telescopic axis is positioned on the left of the left steering axis in the left-right direction of the body frame when the vehicle in which the body frame is standing upright is viewed from the front in the front-rear direction of the body frame; the right shock absorber is disposed such that the right telescopic axis is positioned on the right of the right steering axis in the left-right direction of the body frame when the vehicle in which the body frame is standing upright is viewed from the front in the front-rear direction of the body frame.
