Document Type and Number:
Japanese Patent JP2019023616
Kind Code:
A
Abstract:
To provide a mechanical coupling device for a watch, capable of increasing the torque to be transmitted in a coupling device in which clock coupling, in particular, the vertical coupling, in which two components can be integrated by friction, is performed.SOLUTION: Disclosed is a mechanical coupling device 100, in particular, the mechanical coupling device for a watch or a mechanical transmission device for the watch, which includes: a first part 1 including a first region having at least a first microcavity; and a second part 2 including a second region having at least a second microcavity. First and second regions come into contact with each other in a mechanical coupling structure.SELECTED DRAWING: Figure 1
