PURPOSE:To facilitate working of recessed parts and assembly operation to fit seal members to these recessed parts by forming recessed pats opened on the end parts in the axial direction between both rotating members, fitting seal members in the recessed parts, and providing bearings on the opening side of these recessed parts fitted with the seal members. CONSTITUTION:A right side recessed part 33 and a left side recessed part 19 are respectively formed on the right side end wall 5b and on the left side end wall 5c of an outside rotating member 5. Both recessed parts 33, 19 can be easily worked, as they are respectively opened on the both end parts in the axial direction. The cylindrical part 5a and the right side end wall 5b of the outside rotating member 5 are fitted to the inside rotating member 3, and a seal ring 20 and a backup ring 25 are fitted in the right side recessed part 33. In this case, the assembly operation is easy, as the ring 20 and the ring 25 can be fitted without elastic deformation. Hereafter, a bearing 27 is pressed in from the still more right end part of the backup ring 25 in the axial direction and fixed. As for the left side recessed part 19, same process as the right side recessed apt 33 is performed. |
