Title:
MOUNTING STRUCTURE FOR RESERVOIR TANK AND CAP
Document Type and Number:
Japanese Patent JP2010105670
Kind Code:
A
Abstract:
To provide a mounting structure that reliably prevents leakage of an operating oil.
An oil storage chamber 12 and a nipple 22 are partitioned by a sealing member 4 made of rubber. An annular ventilation passage 28 is defined by the abutment of the sealing member 4 on the recessed portion 23 of a cap 2. A slit 41 in the sealing member 4 is exposed from the ventilation passage 28 on the side of opposite the nipple 22. Since a seal is formed by the rubber elasticity, leakage of the operating oil can be reliably prevented compared with a conventional labyrinth structure.
