The present invention provides a seal sealing member which can enlarge the compression amount and improve the sealing performance. The groove sealing member (20) is provided with a first projection (21), a second projection (22), a third projection (23), a fourth projection (24) and a fifth projection (25), which are successively configured along a circumferential direction of a cross section. At a state of being mounted to the sealing groove (50), the first projection becomes the projection which projects from an open end of the sealing groove. The third projection and the fourth projection respectively abut against a bottom surface of the sealing groove. A first space part which absorbs the deformation amount when the first projection is pressed is formed through a first dent part that is provided between the third projection and the fourth projection and the bottom surface of the sealing groove. A second dent part and a third dent part are respectively provided at a part between the second projection and the third projection and a part between the fourth projection and the fifth projection. A fourth space part and a fifth space part which absorb the deformation amount together with the first space part when the first projection is pressed. |
