Opening/closing operation device for vehicle open/close door

摘要

In an opening/closing operation device for a vehicle open/close door, a handle and a lever for transmitting an unlock operation force to a latch mechanism are turnably supported by an open/close door, and one end portion of the lever is brought into contact with a contact surface formed in the handle. In the contact surface, at least a portion to be in contact with the one end portion of the lever at an initial stage of the manipulation of the handle is formed in an inclined manner or curvedly: in a way that makes the portion situated more forward in a movement direction, in which the contact surface moves in response to the turn of the handle, as the portion comes closer to a rotary fulcrum of the lever in a direction along a plane orthogonal to the movement direction such that the portion intersects the plane.

主权项

1. An opening/closing operation device for a vehicle open/close door, comprising:
a handle having a first end attached to the open/close door and a second end having a guide arm portion extending into the open/close door, the handle configured to swing about the first end when an opening operation force is exerted on the handle such that the second end of the handle including the guide arm portion is displaced from a first position to a second position in the direction of the opening operation force; a latch mechanism configured to maintain a closed state of the open/close door; and a lever pivotally supported by the open/close door, the lever including a first arm portion received within an opening provided in the guide arm portion and a second arm portion configured to transmit the opening operation force to the latch mechanism, wherein a contacting tip of the first arm portion is in contact with a contact surface formed on an inside surface of the opening provided in the guide arm portion and is configured to slide along the contact surface from an initial-stage contact portion to a latter stage contact portion as the handle is displaced from the first position to the second position thereby causing the lever to pivot, wherein the initial-stage contact portion is disposed closer to an exterior of the open/close door than the latter stage contact portion, and wherein the latter-stage contact portion is formed continuously with the initial-stage contact portion along the contact surface and in a plane orthogonal to the movement direction of the guide arm portion such that the latter-stage contact portion comes into contact with the contacting tip of the first arm portion of the lever at a latter stage of the manipulation of the handle.
