US 2003/0154949 A1 · Oil receiver

Abstract

To provide an oil receiver in which friction on a shaft body generated in association with introduction of hydraulic pressure into the oil receiver is alleviated. Therefore, the amount of fuel consumption is reduced and durability is improved. Furthermore, the number of components is reduced, and thus manufacturing and assembly costs can be reduced. An oil receiver includes a connecting oil passage in communication with an inside of the shaft body via a communication hole formed in the shaft body. A lead-in oil passage for introducing lubricating oil into the connecting oil passage extends from the connecting oil passage radially outward. A balance oil passage extends from the connecting oil passage radially outward on an opposite side of the connecting oil passage from the lead-in oil passage. The balance oil passage is closed at an extremity thereof. Accordingly, lubricating oil can be introduced from the lead-in oil passage into the inside of the shaft body,
