Abstract

A clutch 100 includes: an internal gear 3 that includes a gear tooth formed on an inner-surface side thereof; a sun gear 4 that is disposed on the same shaft at a central portion of the inner side of the internal gear 3; one or more planetary gears 5 that are disposed between an outer circumferential surface of the sun gear 4 and an inner surface of the internal gear 3; a carrier 6 that is provided with a boss portion 6a that supports rotatably the planetary gear 5; an electromagnetic coil portion 7; a rotation limit member 8 that is slidably inserted into the electromagnetic coil portion 7 in a shaft direction and selectively disposed at a first position for limiting rotation of the internal gear 3 or the sun gear 4 or at a second position for permitting the rotations of the internal gear 3 and the sun gear 4; and an elastic member 9 that is disposed between the electromagnetic coil portion 7 and the first flange portion 8b of the rotation limit member 8.

Description

technical field [0001] The present invention relates to a planetary gear type clutch using a planetary gear mechanism. Background technique [0002] Conventionally, in the case where a plurality of driven parts are driven separately, if driving devices such as motors etc. are provided in number equal to the number of driven parts, the cost of the device increases. In order to avoid this, generally the driven part is driven by using one driving device; and a clutch mechanism that performs transmission and interruption of the driving force is provided between the driving device and the driven part. [0003] As a clutch mechanism, JP-A-2006-292120 discloses a planetary gear type clutch including a planetary gear mechanism consisting of: a rotatable internal gear; a sun gear, which is rotatably disposed inside a central portion of the gear; a planetary gear that meshes with the sun gear and the inner side of the internal gear and rotates around the sun gear while rotating aroun...
