When disassembling after a gas being supplied into a tube member, the gas in the tube member is discharged before the tube member and a moving member become separable. In a webbing take-up device, a cover plate cannot be removed from a frame and thereafter a cylinder and a piston inside the cylinder cannot be separated before covering of a fixing screw with a covering section of a plate being released by removing a screw from an exhaust port of the cylinder and by removing the plate from the cylinder. Thus, after a high-pressure gas being supplied into the cylinder, the high-pressure gas inside the cylinder can surely be discharged by removing the plate from the cylinder and the exhaust port is opened by the screw before the cylinder and the piston being separated. |
