摘要： A seal device is adapted to be mounted at an area of relative rotation between two mounting portions of a tire pressure-adjusting device. The seal device includes a pair of first and second seal rings which are disposed in opposed relation to each other. Each of the first and second seal rings includes a main seal of an annular shape having a radially inwardly-directed lip formed on an inner periphery of the main seal, the lip having at its distal end a lip sliding surface to which a self-lubricating thin plate for sliding contact with one of the two mounting portion. Each seal ring further includes an auxiliary seal of an annular shape having a radially inwardly-directed lip which is formed on an inner periphery of the auxiliary seal and is adapted for sliding contact with the one mounting portion, the auxiliary seal being connected to the main seal to form therebetween a closed space for holding grease. A valve is mounted on each of the auxiliary seals for effecting the intake and exhaust of air relative to the closed space.

摘要： A flexible boot for a constant velocity universal joint includes: attachment portions to a mating member at both ends; and a bent portion provided between the attachment portions and absorbing deformation caused by operation of a constant velocity universal joint. The flexible boot is made of a rubber material obtained by blending 50 to 80 parts by weight of HNBR having an acrylonitrile content of 15 to 21 wt % and 20 to 50 parts by weight of EPDM, the rubber material having an elastic recovery rate of 18% or more at −40° C. in a TR test.

摘要： The invention relates to a CVJ boot in which contact pressure of crest portions closer to a large-diameter mounting portion on the compressed side of a bellows portion is reduced when slant faces forming a root portion of a bending point obtained by the S-shaped bend come into contact with each other, thereby increasing durability.

摘要： A flexible boot for a constant velocity universal joint (CVJ) includes a smaller-diameter mounting portion provided at one end, a larger-diameter mounting portion provided at the other end, and a bellows portion provided between both of the mounting portions. The larger-diameter mounting portion and the bellows portion are connected to each other by a straight portion, and the smaller-diameter mounting portion and the bellows portion are connected to each other by a straight portion. An axial distance of each of the straight portions is equal to or larger than 20% of an entire axial distance from a boundary between the larger-diameter mounting portion and the adjacent straight portion to a boundary between the smaller-diameter mounting portion and the adjacent straight portion, and an axial distance of the bellows portion is in a range of 20% to 60% of the entire axial distance, so that the bellows portion is located substantially centrally in an axial direction between both of the straight portions.

摘要： A flexible boot having a bellows and mount portions on both axial ends of the bellows portion at which the boot is mounted on parts of a mechanism such as an automotive constant velocity joint. The flexible boot has an anti-degradation agent make-up element made of a material which contains an anti-degradation agent and which is capable of allowing the anti-degradation agent to precipitate on the surface thereof. The anti-degradation agent make-up element is fitted on at least a portion of the outer surface of the bellows so that the anti-degradation agent precipitated on the surface of the material of the anti-degradation agent make-up element is caused to progressively immigrate into the material of the bellows thereby making-up the anti-degradation agent in the bellows.
