A plate 42 is fitted and inserted in a large diameter inner peripheral face 44 and an intermediate inner peripheral face 45 of the case 41, and the plate 42 is tightened integrally with the case 41 by screw members 47. The reducer main body 62 is fitted and inserted in the large diameter inner peripheral face 44 of the case 41, and is tightened by screw members 63. An O-ring 64 is disposed between the joint faces of the case and the reducer body to liquid-tightly seal a case drain chamber 65 of the reducer main body 62. COPYRIGHT: (C)2006,JPO&NCIPI
