1. A webbing take-up device comprising: a winding shaft that winds a webbing applied to a passenger of a vehicle by rotating in a winding direction; a tube member, into one side of which a gas is supplied at a predetermined occasion; a moving member mounted to the tube member by a removable mounting member, the moving member being that is moved to the other side of the tube member by pressure of the gas supplied into the one side of the tube member thereby rotating the winding shaft in the winding direction; a removal member at which an attachment portion attachable to the tube member is formed, and a restriction section which interferes with the separation of the tube member and the moving member when the removal member is attached to the tube member is formed, the removal member including the attachment portion and the restriction section being a one piece member; and a closing member that closes an exhaust port formed in the tube member and allows the gas inside the tube member to be discharged via the exhaust port to an outside of the tube member by the exhaust port being opened when the removal member is removed, wherein the closing member attaches the attachment portion of the removal member to the tube member, and the exhaust port is formed at a location of the tube member such that the exhaust port communicates an inside portion of the tube member where the gas is supplied in a pressurized state with an outside of the tube member.
