To achieve said purpose, a gripping device 1 comprises: a main body 10, which has a core part 14 and in which an annular space 15, with a shaft center that coincides with the shaft center of the core part, is formed around the core part; an elastic rubber body 50 that is fitted inside said annular space of the main body so as to form, with the surrounding wall that defines the annular space, a pressure chamber 16, and so as to form, with the core part, a gap into which a tubular member to be gripped can be inserted; and a passage 17 into which a fluid is introduced into said pressure chamber. The elastic rubber body is made to inflate in the direction of the core part by the pressure of the fluid introduced to the pressure chamber via the passage, and the tubular member to be gripped that has been set on the core part is gripped by the core part and the inflated elastic rubber body.
