Title:
LOCK MECHANISM FOR STOPPING ROTATIONAL SHAFT
Document Type and Number:
Japanese Patent JP2020165509
Kind Code:
A
Abstract:
To stop the rotation of a rotational shaft even in a case where the rotational shaft of a motor is rotating at high speed.SOLUTION: A plurality of engaging concave parts 210, 212 are formed in an engaging ring member 202 externally fitted to a drive rotational shaft 112 of a vertical displacement motor 104. A lever member 220 is engaged with either one of the engaging concave parts, to prevent further rotation of the rotational shaft 112. Here, the engaging concave parts 210, 212 are separated from each other along a circumferential direction of the engaging ring member 202 with a plurality of partition walls 206, 208, which are relatively convex parts, interposed therebetween. The distance (or a central angle) between the plurality of partition walls 206, 208 is set so that the distance between the engaging concave parts 210, 212 is made uneven.SELECTED DRAWING: Figure 5
