摘要： A rod-end bearing device includes a ball seat crimped in place within an inner chamber of a housing. A ball head of a ball stud slides in the ball seat. An insertion hole for the ball stud flares outward at its outer end. A thick pressed portion contacts the housing around the outer surface of the ball seat, near the insertion hole. An indented portion around the outer perimeter of the pressed portion adjacent the insertion hole receives an annular raised portion of a dust cover. A generally thick portion of the ball seat transmits forces from contact by the stud portion of the ball stud to the housing when the ball stud is at its maximum angular extent. The force transmission is defined by a force line from the contact point to the housing. The indented portion is located axially outward from the force line. This separation of the indented portion from the force line retains the sealing ability of the dust cover.

摘要： A ball joint uses a single-piece ball seat of hard plastic that has high rigidity, high load durability and elasticity, to prevent premature fracture of the ball seat caused by manufacturing imperfections in the socket of the ball joint. A preload contact surface is resilient supported at the top of the ball seat to enable uniform distribution of preload of the ball to the socket. At assembly of the ball joint, a cylindrical lower portion of the ball seat cylinder is reshaped into an inwardly bowed surface to envelop the lower portion of the ball. A thin annular wall at the periphery of the preload contact surface of the ball seat defines a thin annular space between itself and the upper portion of the ball seat cylinder to provide the preload contact surface with expansion space. Additional elasticity can be built into the ball seat by providing slits at the junction of the preload contact surface periphery and the base of the thin annular wall.

摘要： The present invention provides a rotary damper capable of reducing the variation in size of a gap through which viscous liquid passes when the viscous liquid moves. from a pressure chamber to a non-pressure chamber, and capable of obtaining stable braking characteristics. The rotary damper of the invention comprises a vane member 30 having an upper end surface 30a, a lower end surface 30b and a tip end surface 30c. The vane member 30 is disposed in a liquid chamber partitioned by the partition wall 10d in which viscous liquid is charged such that as the rotation shaft 20 rotates, the vane member 30 can rotates while allowing its upper end surface 30a, lower end surface 30b and tip end surface 30c to respectively slide on a lower surface 60b of a closing member which closes an opening of the body case 10, an inner surface of a bottom wall 10e of the body case 10 and an inner peripheral surface 10c of the body case 10, the vane member 30 partitions the liquid chamber into a pressure chamber and a non-pressure chamber. The rotary damper further comprises a liquid passage 80 which has a large hole portion 81 and a small hole portion 82 smaller than the large hole portion 81, which penetrates the vane member 30 in a direction substantially parallel to an axial direction, the large hole portion 81 being in communication with the pressure chamber, and the small hole portion 82 being in communication with the non-pressure chamber, and a valve body movably disposed in the large hole portion 81 of the liquid passage 80.
