To suppress detection dispersion and secular change, and perform high accuracy detection, by integrating a rotary shaft rotated by being interlocked to accelerator operation and a sensor rotary shaft for producing in a sensor part, a relative rotational rate against the main body of the rotary shaft.
An extended part 3A which is extended by being passed through the sensor part 80 of a rotary sensor 50, is arranged on a rotary shaft 3 connected to a drum 2 which is interlocked to accelerator pedal operation, and connected to a hysteresis producing mechanism part 10. This mechanism part 10 is equipped with a return spring 21, which produces force by which the rotary shaft 3 is returned to an initial position when the rotary shaft 3 is rotated, and at the same time, produces force by which the rotary shaft 3 is moved to the drum 2 side against a housing 90. Hereby, a rotary plate 14 on the rotary shaft 3 is moved finely to the drum 2 side while being rotated, and force that frictional force corresponding to the rotation of the rotary shaft 3 and frictional force by the reaction of a wave washer 11, are superposed to each other, can be produced between the rotary plate 14 and a sliding member 12.
