Beschreibung
Zusammenfassung:	An accelerator device includes an accelerator arm 12 provided with an accelerator pedal 11, a support case 13 internally holding and supporting an arm base part 12a through a support shaft 14, a return spring 16 and 17 for urging the arm 12 to rotate in a returning direction to return the pedal 11 to an initial position, and an accelerator sensor 15 for detecting a rotation amount of the arm 12 as an accelerator opening degree. A hysteresis producing mechanism includes friction pieces 20 and 21 attached to the arm base part 12a. A curved contact surface 20a of the friction piece 20 is held in contact with a contacted surface 19a of a friction part 19 of the support case 13. One end of the return spring 16 and 17 is hooked in one end of the friction piece 20 and 21, and the other end of the spring 16 and 17 is connected to the arm base part 12a in order to press the contact surface 20a and 21a of the friction piece 20 and 21 against the contacted surface 19a of the friction part 19.
