イ式駆動ユニツト。 In a drive unit that uses a mainspring as a drive source and transmits its elastic force to an output shaft via a reduction gear mechanism, a constant speed mechanism is provided that brakes the rotation of the reduction gear mechanism to rotate it at a constant speed, and the constant speed mechanism is engaging the reduction gear mechanism via a switching gear, and supporting the switching gear on a gear box so as to be movable in a direction away from the constant speed mechanism while being engaged with the reduction gear, and supporting the switching gear and switching. When the gear is connected to the constant speed mechanism, the tip protrudes outside the gear box and engages with the gear box, and when the tip collides with a convexity on the running surface, the engagement is released and the switching gear is connected to the constant speed mechanism. A 2-speed spring type drive unit characterized by a switching lever that disconnects the drive unit.
