PROBLEM TO BE SOLVED: To provide a gear transmission mechanism in which smooth slide operation of an Oldham coupling member can be secured.SOLUTION: An internal gear 2, an external gear 3, an eccentric shaft member 4 and an Oldham coupling member 5 are accommodated in a housing 1. The external gear is arranged so that a part of external tooth is meshed with the internal gear, and the external gear is rotatably supported with an eccentric shaft as a center, the eccentric shaft being arranged on a plane including a rotating shaft which is parallel with and prescribed distance offset from the eccentric shaft. The Oldham coupling member has a guide hole in which a main body shaft part of the eccentric shaft member is accommodated, and the main body shaft part is rotatably supported in the guide hole. Shaft members (pins 7, 7) are held at a rotation face of the external gear at a side opposite to the Oldham coupling member, slide members 8, 8 are rotatably supported around the shaft members, and the Oldham coupling member is slidably supported with respect to the external gear via the slide members.SELECTED DRAWING: Figure 1 【課題】オルダム継手部材の円滑な摺動作動を確保し得る歯車伝動機構を提供する。【解決手段】ハウジング１内に、内歯車２、外歯車３、偏心軸部材４及びオルダム継手部材５が収容されている。外歯車は、内歯車に外歯の一部が噛合するように配置され、回転軸を含む面上で平行に所定距離オフセットした偏心軸を中心に回転可能に支持され、オルダム継手部材は、偏心軸部材の本体軸部が収容される案内孔を有し、案内孔内に本体軸部が回転可能に支持されている。オルダム継手部材に対向する側の外歯車の回転面には、軸部材（ピン７、７）が保持されると共に、その回りに摺動部材８、８が回転可能に支持され、これらの摺動部材を介してオルダム継手部材が外歯車に対し摺動可能に支持されている。【選択図】図１
