The present invention addresses the problem of providing a stopper which enables easy insertion of a sealing member (3) into a stopper member (2), and which enables preventing the sealing member (3) from being removed from the stopper member (2). The stopper is provided with: a stopper body (1) which has a guiding path (10) extending in the axial direction; a stopper member (2) which has a flow path (22) extending in the axial direction and is inserted into the guiding path (10) of the stopper body (1); and a sealing member (3) which is inserted into, in such a manner as to block, the flow path (22) of the stopper member (2). The stopper member (2) is provided with: a first peripheral wall section (27) which is fixed, in such a manner as to extend in the axial direction, at a position where the sealing member (3) is inserted; and a second peripheral wall section (28) which is divided along the axial direction in such a manner as to open outwardly in the radial direction. |
