Operation Amount Detection Device For Bar Handle Vehicle

Abstract: An operation amount detection device (50A) is for a bar handle vehicle in which a pivot (40) fixed to a holder (10) is inserted into one end of a pivot insertion hole (25) of a brake lever (20A), and the brake lever (20A) is rotatable around the axis of the pivot (40). The operation amount detection device (50A) comprises a rotation angle sensor (51) fixed to the holder (10), and a detection shaft (55) fitted to the other end of the pivot insertion hole (25). The brake lever (20A) and the detection shaft (55) rotate together, and a magnet (58) is provided on the detection shaft (55). A magnetic detection unit (53) of the rotation angle sensor (51) faces the magnet (58) in a non-contact state and detects the amount of rotation of the magnet (58). With this configuration, it is possible to prevent water and foreign matter from entering the rotation angle sensor (51) with a simple structure.
