  • Passage connecting structure and master cylinder using the same
    Patent number: 7762632
    Abstract: A connecting structure between two passages includes a connecting sleeve including a large-diameter portion and a small-diameter portion with a shoulder surface defined therebetween. A recess is formed in the shoulder surface at its radially inner portion. When the connecting sleeve is inserted into a connecting hole formed in a mating member with a seal member fitted on the small-diameter portion, the seal member is radially compressed and is allowed to swell not only in the direction in which the connecting sleeve is inserted but toward the shoulder surface because the shoulder surface is formed with the recess. This prevents the force that tends to axially slide the radially inner portion of the seal member, thus preventing inclination of the seal member.
