摘要： PROBLEM TO BE SOLVED: To prevent the partial wear, and to increase the service life by reducing the camber of a pad. SOLUTION: At least one slit 11 to split a pad into a plurality of parts in the longitudinal direction of a brake shoe 1 is provided. The slit 11 pierces the pad 2 from a face side to a back side leaving a part thereof, a wear detection groove 13 is provided on the extension of the slit 11 in a connection part 12 to connect the pads 2 on both sides left on one part of the slit 11, and the depth of the detection groove 13 corresponds to the wear limit from the surface of the pad 2.

摘要： PROBLEM TO BE SOLVED: To make easy loading of a load sensitive type shock absorber on a vehicle, and ensure riding comfortableness of the vehicle while the damping ratio is kept in a prescribed range when a variable control of the damping characteristics is performed. SOLUTION: The base end sides of respective valve springs 15, 16 provided on the back faces of an extension side damping valve 13 and a pressure side damping valve 14 arranged on a piston 4, are individually supported by adjusting cylinder mechanisms 23, 24, and the internal pressure of an air suspension device is introduced from outside to the adjusting cylinder mechanisms 23, 24 through a conduction passage 29 provided in a piston rod 5. As the internal pressure is changed, the adjusting cylinder mechanisms 23, 24 switch preset loads of the valve springs 15, 16 to adjust the cracking pressure of the extension side- and pressure side damping valves 13, 14, and the generated damping characteristics are variably controlled continuously or in two stages in elevation in accordance with the change in the internal pressure of the air suspension device.

摘要： PROBLEM TO BE SOLVED: To enhance productivity of a caliper main unit so as to attain reduction of a cost while maintaining a replacing function of a brake pad, by mounting an engagement holding plate with dovetail groove in the caliper main unit so as to fit here the brake pad capable of mounting/demounting. SOLUTION: A brake pad 3B is constituted by fixing a lining 17 to a guide plate 16, a brake pad 3A, 3B arranged in both sides of a disk rotor 1 is supported to a brake caliper main unit 4. An engagement holding plate is mounted in the caliper main unit 4, both sides of this engagement holding plate are folded back, a dovetail groove is formed, relating to this dovetail groove of the engagement holding plate, the guide plate of the brake pad 4 is fitted to be held.

摘要： PROBLEM TO BE SOLVED: To simplify structure, to improve processability and assembly ability, and to reduce a cost. SOLUTION: This base isolation and vibration-control device comprises a body mass 11; a ball body receiving part 12 for the lower part of the body mass 11; a spherical body 14 rotatably fitted in the central spherical surface of the ball body receiving part 12; a spherical seat 16 formed in the under surface of the body mass 11 opposite to the spherical body 14; ball reservoirs 17a and 17b formed in the body mass 11 and the ball body receiving part 12 and connected to the end part of the spherical seat 16; and a number of ball bearings 18 rotatably contained between the spherical body 14 and the spherical seat 16 and in the ball reservoirs 17a and 17b. The body mass 11 is coupled to a member on the moving side and the spherical body 14 is rotably arranged on a conical recessed part 20 of the seat part 19 on a fixed side, and horizontal relative displacement between the member on the moving side and the seat part 19 on the fixed side is permitted. The ball reservoirs 17a and 17b consist of an annular groove vertically formed in the body mass 11; and a curved annular groove formed between the under surface of the body mass 11 and the upper surface of the spherical receiving part 12.

摘要： PROBLEM TO BE SOLVED: To prevent overall warping by constituting a brake pad by installing a lining making pressure contact with a disc rotor on a back plate and forming a favourably deformed part positioned in the neighbourhood of both ends in the longitudinal direction of this back plate and weakened in rigidity. SOLUTION: Brake pads 3 are respectively installed on a forked fork part 4 of a brake caliper 2, and the brake pads 3 are fixed on a back surface of a lining 7 making pressure contact with a disc rotor 1 by installing a back plate 8 through a rivet 9. Thereafter, the brake pads 3 are formed long in the circumferential direction of the disc rotor 1, thickness of a section of the back plate 8 is gradually reduced in the neighbourhood of both ends in the longitudinal direction, and a tapered part 10 as a favourably deformed part rigidity of which is weakened is formed. Consequently, it is possible to reduce overall curvature of the brake pads 3.
