Abstract

A throttle grip apparatus is provided with: a throttle grip (1) rotatably mounted on a leading end of a handle bar (H) of a vehicle; a magnet (6) rotatable together with the throttle grip (1); a detector (13) for detecting variations in a magnetic field of the magnet (6) in a non-contact manner to detect a rotation angle of the throttle grip (1); and a frictional plate (9, 10) for generating a rotation load of the throttle grip (1). An engine of the vehicle is controlled based on a detected value of the detector (13). The frictional plate (9, 10) is disposed within the handle bar (H).

Claims

1. A throttle grip apparatus comprising:

a throttle grip rotatably mounted on a leading end of a handle bar of a vehicle;

a magnet rotatable together with the throttle grip;

a detector configured to detect variations in a magnetic field of the magnet in a non-contact manner to detect a rotation angle of the throttle grip based on a detected value of the detector; and

a frictional plate configured to generate a resistance to a rotation of the throttle grip to generate a rotation load of the throttle grip,

wherein an engine of the vehicle is controlled based on the detected value of the detector, and

wherein the frictional plate is disposed within the handle bar.

2. The throttle grip apparatus according to claim 1, further comprising:

a resistance adjustor configured to adjust the resistance generated by the frictional plate.

3. The throttle grip apparatus according to claim 2, wherein the frictional plate includes:

a rotation side frictional plate rotatable together with the throttle grip; and

a fixed side frictional plate which is fixed to an interior of the handle bar and is in contact with the rotation side frictional plate, and

wherein the resistance adjustor includes;

an urging member configured to press the rotation side frictional plate against the fixed side frictional plate; and

an adjusting mechanism configured to change an urging force of the urging member from outside,

wherein, by operating the adjusting mechanism, a pressing force of the rotation side frictional plate against the fixed side frictional plate is adjusted.

4. The throttle grip apparatus according to claim 3, wherein the adjusting mechanism includes a tool fit-shape portion facing a leading end of the throttle grip, and the urging force of the urging member is changed by fitting a tool with the tool fit-shape portion and rotating the adjusting mechanism.
