Document Type and Number:
Japanese Patent JP2019053857
Kind Code:
A
Abstract:
To provide an operation device for a switch that has a novel configuration where failures are further reduced, for example.SOLUTION: In an operation device for a switch, the switch is switched by rotating an operation shaft. A main rotation member of a rotation transfer mechanism is provided in a rotatable manner around a shaft center and rotated which being interlocked with the operation shaft in a predetermined angle range, and includes a pushing part in an end radially outside of the shaft center. A slave rotation member of the rotation transfer mechanism is provided in a rotatable manner around the shaft center, includes a receiving part which is pushed in a circumferential direction of the shaft center by the pushing part, in a radially outside end and is rotated by the main rotation member. One of the pushing part and the receiving part extends in an axial direction of the shaft member, and the other of the pushing part and the receiving part extends in the radial direction of the shaft center. A circumferential clearance gap to which the pushing part and the receiving part are not abutted during the rotation of the main rotation member at a predetermined angle is provided between the pushing part and the receiving part. An actuation part is actuated by rotating the slave rotation member.SELECTED DRAWING: Figure 2
