Throttle grip device

A throttle grip device comprising:

• a throttle grip which is rotatable by a driver, and which is capable of normal rotation in a predetermined direction from an initial position and reversed rotation in a direction opposite to the predetermined direction;
• an interlocking member which includes an engaged portion capable of being engaged with an engaging portion formed on the throttle grip, and which is capable of rotating in conjunction with the normal rotation and the reversed rotation of the throttle grip;
• a case which is configured to rotatably hold the interlocking member;
• a first urging unit which is configured to urge the interlocking member toward the initial position when the throttle grip is subjected to the normal rotation;
• a second urging unit which is configured to urge the interlocking member toward the initial position when the throttle grip is subjected to the reversed rotation;
• and
• a rotation angle detecting unit which is capable of detecting a rotation angle of the throttle grip by detecting a rotation angle of the interlocking member,
• wherein the throttle grip device is capable of controlling an engine of a vehicle in accordance with the rotation angle of the throttle grip detected by the rotation angle detecting unit when the throttle grip is subjected to the normal rotation, and is capable of activating or deactivating a predetermined function of the vehicle when the throttle grip is subjected to the reversed rotation, and
• wherein the throttle grip device further comprises:
• a pressing unit which is capable of pressing the engaging portion against the engaged portion by an urging force of the second urging unit when the throttle grip is in the initial position.
