The magnetic sensor 6 (rotation angle detecting means) is composed of a sensor arranged at a position on an extension line of an extension portion Bb which is a rotation axis of the interlocking member 1, and is magnetic generated from a magnet 3 attached to the interlocking member 1. By detecting the change, the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 6 can obtain an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet 3. For example, a Hall element (specifically, a Hall element) which is a magnetic sensor utilizing the Hall effect. Is composed of a linear Hall IC) or the like that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet 3. The magnetic sensor 6 according to the present embodiment is formed on a substrate 7 (printed circuit board) on which a predetermined electric circuit is printed.

Then, when the interlocking member 1 rotates with the rotation operation of the throttle grip G, the magnet 3 attached to the interlocking member 1 also rotates in the same direction by the same angle. As a result, since the magnetic field changes depending on the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 1 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to do. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to the ECU (engine control unit) mounted on the motorcycle, and the rotation angle of the throttle grip G of the vehicle is transmitted according to the transmission rotation angle of the throttle grip G.

That is, the fixed side end portion 8b of the torsion coil spring 8 is fixed to the extending portion Bb of the balancer B via the fixing member 4.

Then, when the holder 2 rotates with the rotation operation of the throttle grip G, the movable side end portion 8a of the torsion coil spring 8 also moves in the rotation direction of the holder 2, while the fixed side end portion 8b of the torsion coil spring 8 moves. Since it is fixed, an urging force for returning the throttle grip G to the initial position is generated. Therefore, by loosening the force for gripping the throttle grip G, the throttle grip G naturally returns to the initial position by the urging force of the torsion coil spring 8.

According to the above embodiment, the torsion coil spring 8 (the urging means) is arranged in the handle pipe H, and its movable end portion 8a is connected to and fixed to the rotatable holder 2 together with the throttle grip G. Since the side end portion 8b is connected to the extension portion Bb of the balancer B (fixed to the extension portion Bb via the fixing member 4), the space in the handle pipe H can be effectively utilized and attached.
