1. A shaft supported by the housing is provided in the housing, and a rotary body for power transmission is rotatably supported on the shaft via a bearing, and is adjacent to the rotary body or the rotary body in the axial direction. An oil passage extending in the radial direction is formed in an adjacent member such as a washer, and the oil passage is offset from the bearing in the axial direction to splash oil on the outer end opening of the oil passage in the radial direction. On the other hand, in the lubricating structure of the power transmission device in which the inner end opening of the oil passage communicates with the axial end portion of the bearing, the hole core of the oil passage gradually increases from the outer end opening toward the inner end opening. A lubricating structure for a power transmission device in which the oil passage is bent toward the axial end of the bearing.
