PROBLEM TO BE SOLVED: To stabilize a sealing property in a bead connecting part by arranging beads on an outer seal part and an inner seal part of a gasket, and connecting the beads to the connecting part of a seal part in a three-pronged fork shape. SOLUTION: An outer seal part 31 seals an outer part of a compressor. An inner seal part 32 seals a high pressure region 16 which is separately arranged in a housing, and a space formed between low pressure regions 14, 15. Both end rims of the inner seal part 32 are brought into continuously contact with the external seal part 31 extending in the outer peripheral direction. Beads 41, 42 which are curved and projected are arranged on the outer seal part 31 and the inner seal part 32 in order to improve sealing property. Relative continuous anglesθof the beads 41, 41, 42 which are brought into continuously contact with each other, in a three-arranged fork shape are uniformly formed in a continuously contact part of both seal parts 31, 32. Each of beads 41, 41, 42 formed in the vicinity of the continuously contact part hold rigidity balanced mutually, each of beads 41, 42 are elastically deformed stably, and a good sealing property is exhibited.
