Claims

[Claims for Utility Model Registration] A drive shaft rotatably supported with respect to a frame, a drive mechanism that reciprocates the drive shaft within a certain angle range, and a drive mechanism disposed so as to share an axis with the drive shaft. an operating shaft rotatably and slidably supported through a pedestal fixed to the frame, and provided to be rotatable and axially displaceable relative to the drive shaft; a drive shaft-side clutch member fixed to the drive shaft, a driven clutch member rotatably and slidably fitted to the operating shaft, and the driven clutch member is moved to a first position in the rotational direction and from the first position. a releasable lock mechanism that locks at a second position separated by a certain angle; and a releasable lock mechanism that is configured to be coupled to either the drive shaft side clutch member or the driven clutch member, and is configured to connect the drive shaft side clutch member and the driven clutch member. a first coupling position, which is located between a clutch member and fixed to the operating shaft, and is coupled to the drive shaft side clutch member in a state where the coupling with the driven clutch member is released;
an operating shaft side clutch member that is displaced between a second coupling position where it is coupled to the driven clutch member in a state where the coupling with the driving shaft side clutch member is released; and the driven clutch member and the operating shaft side clutch member. and a rotating body disposed opposite to the pedestal and fixed to the operating shaft; a fixed-side stopper provided on the rotating body in a state that the operating shaft-side clutch member can come into contact with the fixed-side stopper when the operating shaft-side clutch member is in the first coupling position, and abutting with the fixed-side stopper; a movable side stopper for regulating the rotation range of the rotating body to a set range, and the fixed side stopper and the movable side stopper are configured to pull out the operating shaft against the biasing force of the biasing means. A three-position operating device for a switch, characterized in that the operating shaft-side clutch member is disposed to release the restriction on the rotational range of the rotating body when the operating shaft-side clutch member is displaced to the second coupling position.
