Jacobson Holman PLLC
Boot for universal joint
To prevent inverting of a mountain portion of a bellows member when a rotating shaft is angularly displaced, the boot includes a bellows member with large and small diameter mounting members. A first mountain portion nearest the large diameter mounting member rises from the large diameter mounting member. A length (L1) between a top of the first mountain portion and a bottom at the large diameter mounting member side is not more than a length (L2) between the inner peripheral position of the bottom and an end portion of an outer ring at the rotating shaft side. A first valley portion adjacent to the first mountain portion is positioned at the rotating shaft side from the end part.
