Zusammenfassung:To provide oil supply structure capable of successfully supplying lubricating oil to a recessed oil supply portion which is recessed from the end face on one side of a rotary shaft.SOLUTION: In an output shaft 5, a recessed portion 21 which is recessed from the end face on one side is formed and a shaft center hole 23 is formed extending from the recessed portion 21 along the shaft center to the other side opposite to the one side. In the outer periphery of the output shaft 5, an oil intake port 24 is opened, and in the output shaft 5, a communication path 25 communicating the oil intake port 24 with the shaft center hole 23 is formed. Thus, when oil is taken from around the output shaft 5 into the oil intake port 24, the oil taken thereinto flows through the communication path 25 into the shaft center hole 23 and the oil is supplied from the shaft center hole 23 into the recessed portion 21.SELECTED DRAWING: Figure 1 【課題】回転軸の一方側の端面から凹んだ凹状のオイル供給部に潤滑のためのオイルを良好に供給できる、オイル供給構造を提供する。【解決手段】アウトプット軸5には、一方側の端面から凹んだ凹部21が形成され、その凹部21から軸心上を一方側と反対の他方側に延びる軸心穴23が形成されている。また、アウトプット軸5の外周面には、オイル取込口24が開口しており、アウトプット軸5には、オイル取込口24と軸心穴23とを連通させる連通路25が形成されている。これにより、アウトプット軸5の周囲からオイル取込口24にオイルが取り込まれると、その取り込まれたオイルが連通路25を通して軸心穴23に流れ、軸心穴23から凹部21にオイルが供給される。【選択図】図1
