<p>PURPOSE:To effectively secure the feed of lubricating oil, prevent the abrasion of a bearing, and improve the lubrication efficiency by forming a recessed part close to a through hole which communicates to a bearing from a planet plate, on the peripheral edge part of a protecting plate which is held between a rotor and the planet plate. CONSTITUTION:A planet plate 60 has a hole 64 as center which is formed at the center part, projection parts 65 in the equal division on the periphery and through holes 63 which communicate to a bearing formed on a cylinder side, on the rotor side of the projection parts 65. As for the peripheral edge part of a protecting plate 70 which is installed on the sliding surface of the planet plate 60, a guide groove 64 which is formed close to the through hole 63 or a recessed part 66 is formed, closing a part of the through hole 63. The recessed part 66 is set close to the through hole 63, and serves for pouring lubricating oil to the bearing.</p> |
