Accelerator operating device

摘要

An accelerator operating device for electrically controlling the output of a power unit on the basis of the manipulated variable of a controller, by achieving the generation of a frictional resistance using a simple configuration. An accelerator operating device includes an extended portion turned upon the operation of a throttle grip; a torsion coil spring biasing the extended portion in a returning direction while the extended portion is turned; and a friction generating mechanism adding a frictional resistance to the turning movement. The friction generating mechanism includes a compression coil spring applying a pressing force to the extended portion, and a friction member brought into sliding contact with the extended portion by being pressed by the compression coil spring. The torsion coil spring and the compression coil spring are placed coaxially with the extended portion and overlap each other at least partially along the axial direction of the extended portion.

主权项

1. An accelerator operating device which electrically controls an output of a power unit on the basis of a manipulated variable of a controller, wherein the accelerator operating device is arranged in a case and comprises:
a turning member turned upon operation of the controller; a return spring biasing the turning member in a returning direction while the turning member is turned; and a friction generating mechanism adding a frictional resistance to a turning movement of the turning member; wherein the friction generating mechanism includes:
a friction member with a flange portion that extends outwardly in a radial direction of the turning member, with the flange portion facing one side of the turning member,a friction spring which applies a pressing force to the one side of the friction flange for pressing the friction flange against the one side of the turning member,a positioning flange standing on an inner circumference of the case and extending inwardly in the radial direction of the turning member,the positioning flange extending in such a way as to face and be in contact with an opposite side of the turning member, andwherein the friction spring is a coil spring and a portion of the return spring is arranged directly inside the friction spring in a manner such that the friction spring and the portion of the return spring arranged inside the friction spring directly overlap each other in the radial direction at least partially along an axial direction of the turning member.
