<P>PROBLEM TO BE SOLVED: To maximally quickly supply oil to a lubrication requiring part existing in a place separate from an oil introducing side when starting oil supply operation into a through-hole 43a, in a lubricating structure using the through-hole 43a of a hollow shaft 43 as an oil flow passage. <P>SOLUTION: The through-hole 43a of the hollow shaft 43 is formed in a tapered shape of gradually expanding a diameter toward the downstream side from the upstream side in its oil flowing direction. A dam 47 for damming so as to restrict an oil outflow by projecting in the through-hole 43a is arranged on an outer end surface corresponding to a large diameter downstream side opening 43c of the through-hole 43a in the hollow shaft 43. <P>COPYRIGHT: (C)2010,JPO&INPIT |
