  • Accelerator apparatus
    Patent number: 9599035
    Abstract: A pedal spring urges a pedal spring receiving portion to rotate a manipulation member in an accelerator closing direction. The pedal spring has an end portion that contacts a first contact surface of a front segment. A hysteresis spring urges a hysteresis spring receiving portion, which is engaged with the manipulation member, in the accelerator closing direction. The hysteresis spring has an end portion that contacts a second contact surface of the front segment. A step surface is formed between the first contact surface and the second contact surface to limit movement of the end portion of the hysteresis spring.
