PROBLEM TO BE SOLVED: To provide a rear wheel steering device which has a structure capable of supporting planetary gears constituting a planetary gear mechanism properly and maintaining the support state reliably, and enables cost reduction.SOLUTION: A planetary gear mechanism 30 comprises columnar pins 35 which support planetary gears 32 rotatably and fix the planetary gears to a nut member 36, and lock members 38 joined to the tips of the pins. The lock member comprises at least one contact part 38e on a surface facing the planetary gear. Only the contact part can come into contact with the planetary gear. Thus, the planetary gear is supported rotatably around the pin while being interposed between the contact part of the lock member and the nut member, and the support state is reliably maintained without the lock member rotating with the planetary gear.SELECTED DRAWING: Figure 5

    【課題】遊星歯車機構を構成するプラネタリギヤを適切に支持し確実に支持状態を維持し得る構造とし、低コスト化を可能とする後輪操舵装置を提供する。【解決手段】遊星歯車機構30が、プラネタリギヤ32を回転可能に支持しナット部材36に固定する円柱状のピン35と、このピンの先端部に接合する係止部材38とを備える。係止部材は、プラネタリギヤに対向する面に少なくとも一つの当接部38eを有し、この当接部のみがプラネタリギヤに接触し得る。従って、プラネタリギヤは、係止部材の当接部とナット部材との間に介装された状態で、ピンを中心に回転可能に支持され、係止部材がプラネタリギヤと共回りすることなく、確実に支持状態が維持される。【選択図】図5
