摘要： PROBLEM TO BE SOLVED: To provide a rotating shaft seal with a rubber seal member and a resin seal member coping with the higher pressure of a compressor cooling medium, having stable attitude, designing accuracy and improved durability. SOLUTION: A metal plate is embedded in the resin seal member and the outer-diameter ends of the resin seal member and the metal plate are made to abut on the inner periphery face of a circular protecting case. Thus, the resin seal member is rigidly fixed and so the attitude of the rotating shaft seal is stabilized and the shape of the resin seal member is also stably held, therefore reducing a thrusting influence on a rotating shaft due to high pressure and improving the durability of the seal.

摘要： PURPOSE:To provide a seal chain equipped with a seal ring of high reliability which is free from being attacked by an alkali solution for washing, etc. CONSTITUTION:An 0-ring 21 of synthetic rubber to be in tight attachment with the end of a bushing 7 is combined in a single piece with an anti-alkaline ring 22 of plastic to be in tight attachment with a roller link plate 6 and pin link plate 2 in such a condition as fitted in a groove 22 furnished at the inside surface, and thereby a seal ring 20 is formed. Therein the plastic ring 22 covers perfectly the peripheries of the O-ring 21, so that the O-ring 21 is free from risk of hardening upon touching an alkali solution even in case the seal chain is dipped in alkali solution and washed. Therefore, the seal chain has a high reliability because the seal ring 20 exerts its function for a long period of time.
