Abstract:
1. An accelerator device comprising: a support member that is attachable to a vehicle body; a shaft rotatably supported by the support member and rotatable in an accelerator opening direction and an accelerator closing direction, which are opposite to each other; a boss portion attached onto an outer wall of the support member and rotatable integrally with the shaft; a pedal connected to the boss portion and actuatable by a driver; a friction member positioned between the boss portion and the support member, and pressed against an inner wall of the support member when the boss portion rotates in the accelerator opening direction; a rotation angle detector detecting a rotation angle of the shaft relative to the support member; and a biasing member biasing the shaft to rotate in the accelerator closing direction, wherein the support member includes (i) a housing that supports one end portion of the shaft, (ii) a first cover defining an internal space in which the biasing member is housed, and (iii) a second cover engaging the first cover, supporting an other end portion of the shaft, and receiving a pressing force from the friction member, and the first cover has a failure region that fails when the friction member applies an excessive pressing force exceeding a threshold pressing force to the second cover, the threshold pressing force of the friction member causing the second cover to contact the first cover, and the contact with the second cover causing the first cover to fail at the failure region wherein the first cover has a contact portion that contacts the second cover when the pressing force is applied to the second cover, and the contact portion is positioned a distance away from the failure region.
