Claims

[Scope of utility model registration request]

A minute hand gear made of a flat metal plate is inserted into the minute hand shaft with a flange formed at the end of the pinion gear of the minute hand shaft made of synthetic resin, and a plurality of locking pieces formed at an inclination height slightly smaller than the thickness of the flange. It consists of elastic thin plates arranged radially at equal intervals, and a locking pawl formed by bending the tip of each locking piece of the elastic thin plate horizontally through a step is placed on a circumference concentric with the central circular hole of the minute hand gear. A slip device for a minute hand gear, which is fitted into a plurality of provided locking holes.
