<p>An electric lever device including an operation lever 1 including a handgrip 2 held by an operator on one end and a rotational center shaft 3 of the operation lever 1 formed on the other end, a detecting unit 4 for detecting a rotation amount of the rotational center shaft 3, and a holding unit 50 for fixing the operation lever 1 to prevent return, the electric lever device with the detecting unit 4 and the holding unit 50 arranged on a surface perpendicular to an attaching surface S of the electric lever device and a surface perpendicular to the rotational center shaft 3 of the operation lever 1, wherein a detent mechanism 6 is provided 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 C1 direction, and a guide unit 20 for guiding movement in a circumferential direction of the axis C1 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.</p> |
