Claims

[Scope of utility model registration request]

Transmission wheel 18 having an engagement recess 22 in the shaft hole 18A
a central hole 9 into which the transmission wheel 18 is loosely fitted and which is bored from one end; and a ball-fitting horizontal hole 2 which is bored in a radial direction from the central hole 9 and can face the engagement recess 22.
3, a coil spring 26 fitted into the central hole 9, a reduced diameter portion 28 fitted in the center hole 9 so as to be slidable in the axial direction;
A manual operation shaft 25 having a ball engagement circumferential groove 29 with a diameter smaller than 8, and a ball insertion horizontal hole 23 of the rotating shaft 6.
When the reduced diameter portion 28 of the manual operation shaft 25 comes into contact with the engagement recess 22, the transmission wheel 1
8 and an engagement ball 24 that allows the rotary shaft 6 to rotate integrally, and the manual operation shaft 25 is slid against the coil spring 26 so that the ball engagement circumferential groove 29 is connected to the engagement ball 24. A manual operation switching device for an electric rotating shaft, characterized in that the rotating shaft 6 is configured to be rotatable relative to the transmission wheel 18 in an engaged state.
