Patent number: 8047342Abstract: A strut type shock absorber (1) comprises an outer shell (2) and a knuckle bracket (3). A curved portion (4) of the knuckle bracket (3) positioned in close contact with the outer shell (2) comprises a reinforcing flange (7) formed by bending a part of an axial end of the curved portion (4) outward and a no-flange portion (6), both of which are welded onto the outer shell (2). By setting an axial distance (H) from an inflection start point to an inflection end point of the outer circumferential surface of the reinforcing flange (7) to be equal to an axial distance from the inflection start point to the no-flange portion (6), and by forming an insulation portion (9) between the reinforcing flange (7) and the no-flange portion (6), an effectual welding operation and the prevention of molten metal from flowing over the reinforcing flange (7) during welding are realized.Type: GrantFiled: April 10, 2007Date of Patent: November 1, 2011Assignee: Kayaba Industry Co., Ltd.Inventors: Takao Nagasawa, Masaru Fukushima, Masahiro Miwa, Taku Sakashita

Patent number: 7793971Abstract: In a strut type shock absorber (1), a lower cap (2) is welded onto an inner circumferential surface of an outer shell (3) at a step (16) formed in a retreated position from an axial tip of the outer shell (3). The axial tip of the outer shell (3) is welded onto the inner circumferential surface of a knuckle bracket (6) which holds the outer shell (3). Since welding of the lower cap (2) onto the outer shell (3) and welding of the knuckle bracket (6) onto the outer shell (3) are conducted at different positions, the lower cap (2) is welded onto the outer shell (3) without suffering from blowholes irrespective of the material forming the knuckle bracket (6), and as a result, a weld bead (17) having a high degree of air-tightness is formed.Type: GrantFiled: April 11, 2007Date of Patent: September 14, 2010Assignee: Kayaba Industry Co., Ltd.Inventors: Taku Sakashita, Masaru Fukushima, Masahiro Miwa

Patent number: 7441637Abstract: In a hydraulic shock absorber (1), a piston rod (5) protrudes from a cylinder (3) filled with hydraulic fluid. A rebound cushion (8) is fitted to an outer circumferential surface of the piston rod (5) in the cylinder (3). A stopper (6) fixed to the cylinder (3) contacts the rebound cushion (8) at an protrusion limiting position of the piston rod (5) to prevent further protrusion of the piston rod (5). An oil pool (8a, 9, 10, 15) formed in a sliding surface (8a, 14) of the rebound cushion (8) supplies oil to the sliding surface that slides on any of the inner circumferential surface of the cylinder (3) and the outer circumferential surface of the piston rod (5) to ensure smooth relative rotation of the piston rod (5) at the protrusion limiting position and the cylinder (3).Type: GrantFiled: August 1, 2005Date of Patent: October 28, 2008Assignee: Kayaba Industry Co., Ltd.Inventors: Masaru Fukushima, Masahiro Miwa
