ABSTRACT:
A receiving portion2efor rotatably receiving therein a planetary gear3, is formed between a plurality of retaining protrusions2dof a carrier. A connection portion2fextending annularly about a rotation axis L is formed on an outer peripheral of a distal end portion of each retaining protrusion2d. Through this connection portion2f, the distal end portions of the respective retaining protrusions2dare connected to each other. Owing to this arrangement, each retaining protrusion2dis reinforced to minimize its deformation. As a result, deformation of the receiving portion2eis greatly reduced and the planetary gear3receiving in the receiving portion2ecan rotate smoothly.
