PROBLEM TO BE SOLVED: To provide a power transmission device which can simplify the whole structure, and can suppress an increase in size in an axial direction.SOLUTION: A power transmission device includes a first rotating shaft 10 having a first gear 20, a second gear 21 meshed with the first gear 20, a second rotating shaft 11 having an outer periphery on which the second gear 21 is arranged to be relatively rotatable, an axial moving part 15 for relatively moving the second gear 21 to the second rotating shaft 11 in an axial direction during rotation of the first and the second gears 20 and 21, and elastic members 14A and 14B held in the axial direction between the second gear 21 and the second rotating shaft 11 and transmitting torque of the first rotating shaft 10 to the second rotating shat 11 by compression force in the axial direction imparted through the second gear 21 relatively moved by the axial moving part 15.SELECTED DRAWING: Figure 2 【課題】全体の構造を簡素化することができ、軸方向の大型化を抑制することができる動力伝達装置を提供する。【解決手段】動力伝達装置は、第１ギヤ２０を有する第１回転軸１０と、第１ギヤ２０に噛み合う第２ギヤ２１と、外周に第２ギヤ２１が相対回転可能に配置される第２回転軸１１と、第１、第２ギヤ２０、２１の回転時に第２回転軸１１に対し第２ギヤ２１を軸方向に相対的に移動させる軸方向移動部１５と、第２ギヤ２１と第２回転軸１１との間で軸方向に挟まれ、軸方向移動部１５により相対移動する第２ギヤ２１を介して付与される軸方向の圧縮力によって、第１回転軸１０の回転力を第２回転軸１１に伝達する弾性部材１４Ａ、１４Ｂとを備えている。【選択図】図２
