Disclosed is a slip gear structure which is easy to handle at the time of dismantling/assembly and which does not easily suffer breakage even if dismantling/assembly is repeated, and a timepiece equipped with the same. A slip gear structure for a timepiece includes: a gear main body portion in the form of an annular plate having in the outer periphery thereof tooth portions, there being provided spring portions extending across an inner opening; and a positioning member equipped with a small diameter plate-like portion having a central hole with which a shaft is rotatably fit-engaged and a pair of support wall portions arranged on both sides of the central hole and protruding from one surface. When the slip gear structure is in a non-fit-engaged state with respect to the shaft, the spring portions of the gear main body are elastically pressed against side edge portions of the support wall portions, with central spring portions thereof situated between the side edge portions protruding into the central hole; and when the slip gear structure is in a fit-engaged state with respect to the shaft at the central hole, the central spring portions of the spring portions of the gear main body portion are elastically pressed against the shaft for slip engagement with the shaft. |
