る。 A oil supply hole 2 is provided in the center of the input shaft 14 from the inner end surface thereof to the front of the attachment part 19 of the connecting member 17.
0 is formed in the input shaft 14, and an oil supply hole 2 is formed in the input shaft 14.
Oil holes 21 are formed extending from 0 to the outer periphery, and these form a guide hole portion 22. Oil supply hole 20
is formed by a spiral hole or a screw hole. A pumping device 23 is attached to the inner end of the input shaft 14. This pumping device 23 is an axial flow pump 25 equipped with vanes 24 radially, as shown in FIG.
