Abstract

An accelerator-opening-degree detection device for a vehicle includes: a sensor case (5) fixed to a bar-shaped steering handle (H); a rotor (6) arranged adjacent to the sensor case (5), the rotor being coupled with an accelerator grip (G); an accelerator-opening-degree sensor (25) accommodated and held in the sensor case (5), the accelerator-opening-degree sensor configured to detect a rotation angle of the rotor (6); and a return spring configured to urge the rotor (6) toward an initial position. A spiral spring (20) is accommodated in an annular spring-accommodating groove (12) formed in the sensor case (5). In order to form the return spring by the spiral spring (20), an end of the spiral spring (20) on an outer periphery and an end thereof on an inner periphery are respectively locked with the sensor case (5) and the rotor (6), and a narrow portion (12a) is provided in the spring-accommodating groove (12), a resilient belt-shaped plate of the spiral spring (20) being held in the narrow portion (12a) in a state where portions of the resilient belt-shaped plate in the narrow portion (12a) are stacked to be always in slidable contact with each other. Accordingly, it is possible to obtain a favorable acceleration operation feeling over the entire operating range of an accelerator grip while special-hysteresis-generation-means is not provided.
