スシリンダ。[Claims for Utility Model Registration] 1. A cut groove that opens outward to the outside is formed over the entire length of the inner surface of a cylinder whose ends are sealed, and both sides of the inner surface of the cut groove are cut to a certain depth over the entire length. A sealing band made of an elastic material that closes the cut groove is fitted into the cut groove, and both ends of the sealing band are fixed to the cylinder, and the sealing band is inserted into the piston inserted into the cylinder. by inserting the piston into the piston, protruding the connecting portion protruding from the cut groove to the outside, and supplying air to the front chamber or rear chamber of the piston,
In the rodless cylinder, the connecting portion is reciprocated along the cut groove while the seal band is inserted into the insertion passage, and the lip is fitted onto the outer periphery of the piston to connect the cylinder and the seal band. A portion of the lip of the seal ring made of an elastic material that seals around the piston by pressing against the inner surface of the piston, and a portion of the lip that is in contact with both edges of the seal band, and a portion of the lip that is symmetrical on the opposite side from the seal band. A rodless cylinder characterized by a greater pressing force than other parts. 2. The rodless cylinder according to claim 1, wherein the compression stiffness of the seal ring is partially increased. 3. The rodless cylinder according to claim 1, wherein the depth of the fitting groove of the seal ring provided around the piston is partially reduced.
