Document Type and Number:
Japanese Patent JP6678169
Kind Code:
B2
Abstract:
Sealing faces are subjected to fluid lubrication and low friction in a steady operation, and leakage of a sealed fluid and entrance of dust into the sealing faces are prevented. In a sealing face of at least one slide part of a pair of slide parts, a dynamic pressure generation groove 10 is provided so as to be separated not to communicate with a sealed fluid side and a leakage side by land portions on both sealing faces, between an end 10a on the leakage side of the dynamic pressure generation groove 10 and the leakage side, a fluid introduction groove 11 which communicates the dynamic pressure generation groove 10 and the leakage side is provided, and the cross-sectional area of the fluid introduction groove 11 is set smaller than the cross-sectional area of the dynamic pressure generation groove 10.
