Claims

[Scope of utility model registration request]

An intermediate wheel body is provided with a gear on the outer periphery that meshes with the pinion of the fifth wheel that transmits the rotation of the rotor, and a connecting means is provided on both sides in the axial direction, and a gear that meshes with the second hand gear is provided on the outer periphery to correspond to the intermediate wheel body in the axial direction. a second transmission wheel provided with a coupling means on a surface thereof, and a minute transmission wheel provided with a gear on its outer periphery that meshes with the minute hand gear, and a coupling means provided on a surface corresponding to the intermediate wheel body in the axial direction; and the second transmission wheel and the minute transmission wheel are arranged coaxially,
During normal hand movement, the intermediate body is connected to the seconds wheel,
When adjusting the time, there is a connection switching means that connects the intermediate wheel body to the minute transmission wheel, a regulating lever that restricts the rotation of the second hand wheel when adjusting the time, and a gear that meshes with the pinion of the second hand wheel and a pinion that meshes with the minute hand gear. A wheel train structure for an electronic timepiece characterized by comprising a third wheel and a third wheel provided with a clutch mechanism.
