Title:
ANGLE-VARIABLE COUPLING DEVICE FOR TIMEPIECE
Document Type and Number:
Japanese Patent JP2016004046
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coupling device reducing bulkiness for a timepiece, thereby enabling the assembling in an extremely thin movement, and restricting a problem of parasitic deflexion at a moment of coupling.SOLUTION: A connection wheel 1.2 includes a rotary shaft 1.2.1, and the rotary shaft 1.2.1 is rotationally fitted to end portions 1.2.2 and 1.2.3 thereof respectively so as to be inclined with respect to a normal line p of a rotation surface of an inlet wheel 1.1 and an outlet wheel 1.3. At least one end portion of the rotary shaft 1.2.1 is fitted to a movable element 1.6. A ratio of the diameter d of the connection wheel 1.2 to the height h of the rotary shaft 1.2.1 is larger than 1.5:1, where the height of the rotary shaft is an interval between a cross-point of the rotary shaft 1.2.1 with respect to the rotation surface and the end portion fitted to the movable element 1.6.
