Abstract: The present invention relates to a thermoplastic elastomer composition comprising 10 to 80 parts by mass of polyolefin resin (A), 10 to 80 parts by mass of styrene-based thermoplastic elastomer (B), and 1 to 20 parts by mass of at least partially crosslinked rubber (C) (with the total amount of the components (A), (B) and (C) being 100 parts by mass), wherein the composition has a type D hardness (i.e., the instantaneous value) of 35 or more and 70 or less in accordance with JIS K6253, and relates to a molded thermoplastic elastomer product obtained by molding the composition.

Abstract: In an interior of a cylinder tube of a fluid pressure cylinder, a piston unit is provided, which is displaced along an axial direction under the supply of a pressure fluid. The piston unit includes a disk shaped plate body, which is connected to one end of a piston rod, and a ring body connected to an outer edge portion of the plate body. The plate body is connected to the piston rod by plural second rivets, which are punched in an axial direction with respect to the piston rod.

Abstract: In a piston unit of a fluid pressure cylinder a plurality of magnets are disposed through holes provided in a ring body. The magnets are disposed in facing relation to detection sensors that are mounted on connecting rods, and are provided in the same quantity as the connecting rods. Further, a guide rod extending from a head cover to a rod cover is inserted through the interior of the ring body. When the piston unit is displaced along the cylinder tube, rotational displacement is restricted by the piston unit being displaced along the guide rod, whereby the magnets are retained to face toward the connecting rods at all times. Therefore, the position of the piston unit is detected by the detection sensors through the magnets.

Abstract: On inner wall surfaces of a head cover and a rod cover of a fluid pressure cylinder, respective pluralities of first and second spigot pins are installed to project out from the inner wall surfaces. The first and second spigot pins are disposed on circumferences of a predetermined diameter that internally contact or inscribe the cylinder tube. Further, when the cylinder tube is assembled with respect to the head cover and the rod cover, by the flange members of the first and second spigot pins inscribing the inner circumferential surface thereof, the cylinder tube is positioned and assembled coaxially with respect to the centers of the head cover and the rod cover.

The piston unit includes a disk shaped plate body connected to one end of a piston rod, and a ring body connected to an outer edge portion of the plate body. The ring body is connected together with the plate body by a plurality of third rivets that are punched in an axial direction with respect to the plate body.

The piston unit includes a disk shaped plate body connected to one end of a piston rod, and a ring body connected to an outer edge portion of the plate body. The plate body is formed from an elastically deformable metal material, and by the plate body becoming elastically deformed and flexing when the ring body of the piston unit abuts against the head cover or the rod cover, shocks applied with respect to the piston unit are buffered.

Abstract: In an interior of a cylinder tube of a fluid pressure cylinder, a piston unit is displaced along an axial direction under the supply of a pressure fluid, and the piston unit is connected to one end of a piston rod. Further, a rod cover is disposed on another end of the cylinder tube, and in the center thereof, a cylindrical holder is provided that displaceably supports the piston rod. The holder is fixed integrally by a plurality of first rivets, in a state in which a flange member, which is expanded radially outward, abuts against an inner wall surface of the rod cover.
