Throttle opening degree detection device

Abstract

Throttle opening degree detection device (1, 100) for a semi-trailer vehicle, the throttle opening degree detection device (1, 100) comprising: a throttle handle (3) mounted on a handlebar (2) and capable of rotating from an initial position (C1) in one direction (D1) and in another direction (D2); a rotation sensor (46) comprising a rotation synchronization element (38) which rotates with the throttle handle (3) to maintain a rotational state of the throttle handle (3), and a non-synchronous rotation element (44) which is immobile with respect to the rotation of the throttle handle (3); a rotation resistance force application element (40) which rotates with the throttle handle (3) and exerts a resistance force on the rotation;and a receiving housing (10, 110) which is mounted on the handlebar (2) and receives the rotation sensor (46) and the rotation-resistance force acting element (40), wherein the receiving housing (10, 110) comprises a first housing (12, 112) and a second housing (14, 114) when the throttle grip (3) is in the initial position (C1) and when the throttle grip (3) is in a maximum rotation position (C2) on the side of one direction (D1), the rotation sensor (46) and the rotation-resistance force acting element (40) are received in the first housing (12, 112).
