To enable downsizing of a power transmission device for a work machine.SOLUTION: Rotation centers of a first planetary gear mechanism 30 and a second planetary gear mechanism 40 are located on the same straight line. A first rotation transmission element 50 can rotate around a rotation center different from the rotation centers of the first planetary gear mechanism 30 and the second planetary gear mechanism 40. The first rotation transmission element 50 transmits rotation of a first ring gear 34 of the first planetary gear mechanism 30 to a second sun gear 41 of the second planetary gear mechanism 40. The second rotation transmission element 60 can rotate around a rotation center different from the rotation centers of the first planetary gear mechanism 30 and the second planetary gear mechanism 40. The second rotation transmission element 60 transmits rotation of a second ring gear 44 of the second planetary gear mechanism 40 to a first sun gear 31 of the first planetary gear mechanism 30.SELECTED DRAWING: Figure 3

    【課題】作業機械用動力伝達装置の小型化を可能にする。【解決手段】第1遊星歯車機構30と第2遊星歯車機構40とは、それぞれの回転中心が同一直線上にある。第1回転伝達要素50は、第1遊星歯車機構30および第2遊星歯車機構40の回転中心とは異なる回転中心を中心に回転可能である。第1回転伝達要素50は、第1遊星歯車機構30の第1リングギヤ34の回転を、第2遊星歯車機構40の第2サンギヤ41に伝達する。第2回転伝達要素60は、第1遊星歯車機構30および第2遊星歯車機構40の回転中心とは異なる回転中心を中心に回転可能である。第2回転伝達要素60は、第2遊星歯車機構40の第2リングギヤ44の回転を、第1遊星歯車機構30の第1サンギヤ31に伝達する。【選択図】図3
