摘要:
An electric lever device includes a detent mechanism 6 between the rotational center shaft 3 and the handgrip 2. The detent mechanism 6 includes a pressing unit 10 including a through hole 11 formed in an axis C1 direction of the operation lever 1, an extension coil spring 12 inserted into the through hole 11 and balls 13a and 13b provided on both ends of the extension coil spring 12 for generating pressing force in the axis C 1 direction, and a guide unit 20 for guiding movement in a circumferential direction of the axis C 1 and changing the pressing force by changing a guide width in the axis C1 direction to apply a load to the movement of the operation lever 1 together with pulling force of a twisted coil spring 30.
