Title:
RETURN MECHANISM, ACCELERATION MECHANISM, POWER GENERATION DEVICE, TRANSMISSION DEVICE, AND SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/037286
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a return mechanism requiring little force in manipulation. The return mechanism (10) according to one embodiment of the present invention is provided with a first spring (1) which acts between a manipulable part (11) and a movement part (12), and a second spring (2) which acts between the manipulable part (11) and a base part (13). The direction that the second spring (2) acts in when the manipulable part (11) is in a first position is not parallel to the direction that the second spring (2) acts in when the manipulable part (11) is in a second position. The component of the force from the second spring (2) in the moving direction of the manipulable part (11) is smaller when the manipulable part (11) is in the second position in comparison to when the manipulable part (11) is in the first position.
