To provide a driving power transmission device for allowing smooth operation of a specified gear while suppressing backlash of the specified gear with high reliability.SOLUTION: A driving power transmission device 6 includes a housing 60 having a support part 61S, a first face 61P, and a second face 69P. A specified gear 52 has a supported part 52H supported by the support part 61S, a body part 56 formed on a whole periphery of the supported part 52H and having a plurality of gear teeth 52G on an outer periphery, arranged side by side in a peripheral direction of a rotation axis X52, a slide contact face 56P formed on the body part 56 and having a circular ring shape around the rotation axis X52 for slide contact with the first face 61P, and a plurality of energizing slide contact parts 57 formed on the body part 56 and protruded in a cantilevered beam shape while being isolated from one another in the peripheral direction, each energizing slide contact part 57 having energizing force F1 to be applied to the second face 69P for slide contact with the second face 69P.SELECTED DRAWING: Figure 7

    【課題】特定ギヤのがたつきを確実性高く抑制して、特定ギヤを円滑に作動させることができる駆動力伝達装置を提供する。【解決手段】駆動力伝達装置6において、ハウジング60は、支持部61S、第1面61P及び第2面69Pを有する。特定ギヤ52は、支持部61Sに支持される被支持部52Hと、被支持部52Hの全周に形成され、外周に回転軸心X52の周方向に並ぶ複数のギヤ歯52Gを有する本体部56と、本体部56に形成され、回転軸心X52を中心とする円環形状をなして第1面61Pに摺接する摺接面56Pと、本体部56に形成され、周方向において互いに離隔しつつ片持ち梁状に突出する複数の付勢摺接部57であって、第2面69Pに向かう付勢力F1を有して第2面69Pに摺接する各付勢摺接部57と、を有する。【選択図】図7
