Claims

[Claims for Utility Model Registration] A transmission wheel that rotates in conjunction with the movement of the hands, a ring-shaped date dial with a date displayed on its surface, and a ring-shaped date dial on which the transmission wheel and the date dial are rotatably attached, and the transmission wheel rotates in conjunction with the movement of the hands. A main plate in which a guide hole is formed along a circumferential line concentric with the wheel, a gear part that meshes with the teeth of the transmission wheel, a claw part that engages with the teeth of the date wheel, and a guide hole in the main plate. 24 with a shaft portion movably and rotatably inserted into the transmission wheel.
The date wheel is provided with a date wheel that rotates once per hour, and a spring member that presses the date wheel toward the teeth of the date wheel. When the transmission wheel rotates in conjunction with the movement of the hands in this state, the date wheel rotates once every 24 hours as the transmission wheel rotates, and the claws of the date wheel rotate. The date on the date wheel is changed by rotating the date wheel by a predetermined angle, and when the date is corrected, when the date wheel rotates with the claw portion of the date wheel engaged with the tooth portion of the date wheel,
A direction in which the tooth portion of the date wheel presses the claw portion of the date wheel against the elastic pressure of the spring member, and moves the date wheel away from the tooth portion of the date wheel along the guide hole formed in the main plate. An analog clock date mechanism that moves the clock to .
