<p>PROBLEM TO BE SOLVED: To provide an accelerator device that prevents uneven wear of a shaft and a bearing rotatably supporting the shaft.SOLUTION: One end 201 of a shaft 20 connected with a pedal is rotatably supported by a bearing 130 of a bearing part 13. At the one end 201 of the shaft 20, a flange 71 is provided annularly in the circumferential direction of the shaft 20. A wall surface 711 on the bearing part 13 side of the flange 71 is formed in the vicinity of an inner wall 132 of the bearing part 13. Thus, a clearance 211 having a relatively small width, which functions as a labyrinth seal between an internal space of a support member and a clearance 210 formed between an outer wall 203 of the one end 201 of the shaft 20 and an inner wall of the bearing 130, is formed between the wall surface 711 and the inner wall 132. Consequently, invasion of foreign matter into the clearance 210 can be prevented to prevent uneven wear of the shaft 20 and the bearing 130 due to foreign matter.</p> |
