Abstract

A fitting structure has a power transmission member (323) which includes first and second tooth sections (161, 162) arranged at intervals at the outer peripheral edge of the power transmission member and to which power is transmitted, and the fitting structure also has a fitting member (600) which is placed so as to surround the power transmission member (323), has formed therein first recesses (163) for receiving the first tooth sections (161) and second recesses (164) for receiving the second tooth sections (162), and fits to the power transmission member (323). The distance between the outer surface of a first tooth section (161) and the inner surface of a first recess (163) is set greater than the distance between the outer surface of a second tooth section (162) and the inner surface of a second recess (164), and an elastically deformable cushioning member is provided between the outer surface of the first tooth section (161) and the inner surface of the first recess (163).

Description

technical field [0001] The present invention relates to a fitting structure, and particularly relates to a fitting structure including a power transmission member that transmits power and a fitting member that is fitted to the power transmission member. Background technique [0002] Conventionally, a planetary gear mechanism embedded in a gear case of a vehicle has been widely known. For example, the planetary gear mechanism described in Japanese Unexamined Patent Application Publication No. 2006-183824 includes: a sun gear; a pinion gear positioned outside the sun gear and meshing with the sun gear; and a ring gear positioned outside the pinion gear. outboard and meshes with the pinion. Furthermore, each pinion is rotatably supported by a planet carrier, and the planet carrier is fitted into the gear case. [0003] A plurality of protrusions are formed on the outer peripheral portion of the planet carrier, and a plurality of recesses for receiving the protrusions are form...
