Patent ID: 8464691

Claim:
An accelerator device, comprising: a housing; a rotary body which is rotated with accelerator operation; a friction member which is arranged at a periphery of the rotary body while being provided with a contact portion to apply resistance due to friction as being contacted to the rotary body; an urging member having one end side engaged with the rotary body and the other end side engaged with the friction member; and a restriction portion which is arranged at the housing and which restricts rotation of the friction member with urging force of the urging member as being contacted to the friction member, wherein the urging member urges the rotary body in a direction to return to an initial position of rotation against the housing owing to that rotation of the friction member is restricted against the housing by the restriction member when the rotary body is rotated against the housing; and the friction member is urged by the urging member in a direction that the contact portion is pressed to the rotary body having the restriction portion as a fulcrum.
