PROBLEM TO BE SOLVED: To reduce cost of a shock absorbing device by eliminating the processing of a female screw and by reducing man hours for torque setting of a rotary disc 19. SOLUTION: The shock absorbing device has a pressing plate 21 stored in a cylinder case 17 from outside of a belleville spring 20 after storing a disc laminate body, an intermediate plate 23 and the belleville spring 20 in the cylinder case 17. The pressing plate 21 is held in the cylinder case 17 as a protruding part 21a provided at an outer circumference of the pressing plate 21 is pressed in a recessed part 17b provided at an inner circumference of the cylinder case 17 while the belleville spring 20 is bent. With the above structure, it is unnecessary to use a nut to bend the belleville spring 20 nor to form the female screw for fastening the nut at an inner circumference of the cylinder case 17. The man hours for torque setting can be reduced as a bending quantity of the belleville spring 20 can be adjusted according to a press-in depth of the pressing plate 21. COPYRIGHT: (C)2009,JPO&INPIT
