Abstract:
1. An accelerator a apparatus for a vehicle, comprising: a support member that is installable to a body of the vehicle; a shaft that is rotatably supported by the support member; a rotatable body that is rotatable integrally with the shaft, wherein the rotatable body has a boss portion, which is fixed to an outer wall of the shaft; a pedal arm that is fixed to the rotatable body at one end portion of the pedal arm, wherein the other end portion of the pedal arm has a depressible portion that is depressible by a driver; a rotational angle sensing device that is received in an interior space of the support member and sense a rotational angle of the shaft relative to the support member; and an urging device that is received in the interior space of the support member and urges the shaft in an accelerator-closing direction wherein: the support member has a communication passage, which receives the boss portion and communicates between the interior space of the support member and an exterior space the support member; an outer wall of the boss portion, which is parallel to a rotational axis of the shaft, includes a first outer wall, which is located in one circumferential side of the boss portion in an accelerator-opening direction, and the first outer wall has a first projection that projects toward a first inner wall of the support member, which is located adjacent to the first outer wall and forms the communication passage; the outer wall of the boss portion, which is parallel to the rotational axis of the shaft, includes a second outer wall, which is located in another circumferential side of the boss portion in the accelerator-closing and the second outer wall has a second projection that projects toward a second inner wall of the support member, which is located adjacent to the second outer wall and forms the communication passage; the first inner wall has at least one projection, which projects toward the first outer wall; and the second inner wall has at least one projection, which projects toward the second outer wall; the first projection has a first exterior side surface, which is located on an exterior space side of the support member where an exterior space of the support member is located; an angle, which is defined between the first exterior side surface of the first projection and a first imaginary line that is spaced from the first outer wall of the boss portion by a predetermined distance on a radially outer side of the first outer wall, is one of an acute angle and a right angle; the second projection has a second exterior side surface, which is located on the exterior space side of the support member; and an angle, which is defined between the second exterior side surface of the second projection and a second imaginary line that is spaced from the second outer wall of the boss portion by a predetermined distance on a radially outer side of the second outer wall, is one of an acute angle and a right angle.
