摘要： PROBLEM TO BE SOLVED: To prevent direct application of action of an edge part of a clutch friction disk to improve durability by installing a rubber damper through a synthetic resin protector. SOLUTION: Plural claws are selected from a large number of claws formed on the periphery of the clutch friction disk fitted and installed in a clutch housing at even intervals, a narrow part is formed in a base part of each the selected claw, and the rubber damper is installed on each the narrow part through the synthetic resin protector. A width of the installed rubber damper is wider than a width of the claw.

摘要： PURPOSE:To generally apply a seal cock for various kinds of openings of fluid device unit products, by selecting at least two or more same kind or different kind seal caps for external fitting or inserting type to make pairs and connecting respective collars of a pair of seal caps to each other with a connecting piece as a unit. CONSTITUTION:An external fitting seal cap 1 is formed cylindrically and a collar 2 is formed at the periphery of the opening end. An inserting seal cap 3 is also formed cylindrically and a collar 4 of which inward middle is recessed 5, is formed at the peripheral edge of the opening end. And a lip part 6 is formed downward at the outer peripheral end. A protruded part 7 is formed at the outer peripheral face of the inserting seal cap 3 and a screw thread is provided thereon. Respective collars 2, 4 of both seal caps 1, 3 are connected to each other by a connecting piece 10. That is, same or different kind seal caps are selected to constitute a pair of seal caps with at least two or more caps. In this way, the seal cocks can be easily and securely applied for a plurality of pipe end openings or screws in fluid device unit products.

摘要： PROBLEM TO BE SOLVED: To provide a driving force transmission mechanism which has such excellent durability that it can be repeatedly used without breaking a damper main body, and to which freezing protection can be securely provided at a low cost. SOLUTION: In a driving force transmission mechanism 30 to transmit rotation driving force of a prime mover side output shaft through a damper means to a transmission side input shaft, the damper means comprises a damper main body 31 comprising a circular body of rubber-like elastic material provided between a prime mover side case and a transmission side case, engagement receses 33 and engagement holes 32 to be alternately engaged with engagement protrusions 18 provided on the prime mover side case and engagement protrusions 20 provided on the transmission side case in the same plane perpendicular to a shaft direction are provided in the damper main body 31, and relief parts 32a, 32b for preventing generation of cracking in the circular body of rubber-like elastic material are continuously formed with the engagement holes 32.

摘要： PROBLEM TO BE SOLVED: To provide a sprocket 1 formed by integrating a sprocket main body 3 keeping teeth 2 engaging with a chain 10 in the outer periphery thereof and a rubber-made buffer ring 4 for mitigating shock at the engagement of the chain 10, wherein a stable noise reduction effect can be acquired by preventing the chain 10 from coming into contact with a side of the teeth 2 in the sprocket main body 3.
SOLUTION: A chain receiving surface 5 in a buffer ring 4 is formed to be a taper surface which is inclined so as to be lowered toward the outside. The inclination of the taper surface controls the movement of the chain 10 in a direction close to the side of the teeth 2 in the sprocket main body 3 so that the chain 10 is prevented from coming into contact with the side of the teeth 2 in the sprocket main body 3.

摘要： PURPOSE:To obtain a highly reliable, small-sized and lightweight waterproof structure for electric joint box being employed in the electric wiring of a vehicle in which the degree of freedom is increased in the shape at a butt fitting part while decreasing the fitting force and ensuring the waterproof action. CONSTITUTION:A fitting groove 7 of elastomer is made at the butt fitting part 5 of a waterproof cover and an engaging wall 10 having a stopper 11 is projected from the butt fitting part of a box body. The engaging wall 10 is fitted in the fitting groove 7 and clamped at a constricted part 7a where protrusions 8a, 9a are formed. An air reserving part 7b is provided between the top part 10a of the engaging wall 10 and the ceiling part 13 of the fitting groove 7 thus providing a waterproof seal.
