PURPOSE:To shorten an axial length of an oil hole by mounting the first and second members positioned axially adjacent to each other on the periphery of a shaft member and supplying a lubricating oil to the second member through the oil hole formed on the shaft member. CONSTITUTION:The periphery of a shaft member 2 is provided with the first and second members 6, 7 axially adjacent to each other, and lubricating oil is supplied to the second member 7 through an oil hole 18 formed on the shaft member 2. The first member 6 is adapted to surround a port 20 to form a passage space 23 for leading oil from the port 20 to the second member 7 between the first member and the peripheral surface of the shaft member 2. Thus, the axial length of the oil hole mounted on the shaft member can be shortened for the axial length of the passage space so as to heighten working efficiency. |
