Description

This invention relates to a throttle grip device in which the vehicle's power source is controlled based on the rotational operation of the throttle grip. In recent motorcycles, throttle grip devices have become widespread that detect the rotation angle of the throttle grip using a throttle opening sensor such as a potentiometer, and send the detected value as an electrical signal to the electronic control unit installed in the motorcycle. Based on this detection signal, the electronic control unit performs predetermined calculations, and the motorcycle's drive source (e.g., engine ignition timing, intake valve or throttle valve opening/closing) is controlled based on the calculation results. A conventional throttle grip device is, for example, the one disclosed in Patent Document 1. In this conventional throttle grip device, the throttle grip and the interlocking member are connected by engaging an engaging portion formed on the throttle grip with an engaged portion formed on the interlocking member. Engine control is performed by detecting the rotation angle of the throttle grip using a sensor that detects the rotation angle of the interlocking member.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The throttle grip device according to the first embodiment, as shown in Figures 1 and 2, detects the rotation angle of a throttle grip G attached to the handlebar H of a motorcycle (vehicle), and transmits the detection signal to an electronic control unit such as an ECU mounted on the motorcycle to control the drive source (e.g., engine). As shown in Figures 3 to 9, it is configured to include a throttle grip G, a case 1, an interlocking member 2, a biasing means 3, a separate member 4, a rotating member 5, a magnetic sensor 9 (rotation angle detection means), a resistance force applying means 7, and an elasticity applying member D. Case 1 is installed inside a switch case S (see Figures 1 and 2) attached to the tip end of the handlebar H of a motorcycle (vehicle) (the base end of the throttle grip G). It houses various components constituting the throttle grip device and rotatably holds the interlocking member 2 and the rotating member 5. As shown in Figure 5, Case 1 consists of a molded part with a first housing section 1a for rotatably housing the interlocking member 2, a second housing section 1b for rotatably housing the rotating member 5, and a third housing section 1c
