Abstract

Provided is a power transmission member which allows a planetary gear mechanism to be reduced in volume while sufficient strength is guaranteed. A planetary gear holding part (2), a rotating shaft part (3), and a sun gear holding part (4) constituting a power transmission member (1) are formed integrally. The rotating shaft part (3) is substantially cylindrical, and a planetary gear (5) can be passed through the interior of the rotating shaft part (3) and turnably mounted on the planetary gear holding part (2). An open window (23) is formed in the planetary gear holding part (2), and a toothed part (53) of the planetary gear (5) is configured to mesh with a bearing-equipped outer gear (6) through the open window (23).

Description

technical field [0001] The present invention relates to a planetary gear mechanism and a member of the planetary gear mechanism that functions to transmit rotation and torque from a drive shaft to a driven shaft in the planetary gear mechanism. Background technique [0002] Conventionally, a planetary gear mechanism is known as a speed change mechanism for rotational power. As a conventionally known planetary gear mechanism, for example, there is a mechanism constituted by: a drive shaft (input shaft) to which the driving force of a drive source is transmitted to make it rotate; and a sun gear fitted to the drive shaft. And it rotates integrally with the drive shaft; the internal gear is arranged on the same axis with the sun gear with a certain gap with respect to the sun gear; a plurality of planetary gears are arranged in the above-mentioned gap at a certain angular interval and connected to the sun gear. The gear and the internal gear are meshed; the planetary carrier (...
