Abstract:
A rodless cylinder comprising:a cylinder tube for allowing a piston to move reciprocatively along an internal space by the aid of a pressurized fluid supplied through a pressurized fluid inlet/outlet port;a guide frame formed with a recess for accommodating said cylinder tube therein;a slider for making displacement along a longitudinal direction in accordance with a guiding action of said guide frame;a displacement-transmitting member connected to said piston, for transmitting displacement of said piston to said slider; anda load-absorbing mechanism provided for said displacement-transmitting member, for absorbing load exerted on said slider, said displacement-transmitting member, or said piston in horizontal and vertical directions, in a rotational direction about an axis of said cylinder tube, in a rotational direction about a perpendicular to said axis, and in various directions given by combining these directions in a complex manner.
