Boot for Universal Joint
摘要：
To prevent inverting of a mountain portion (111) of a bellows member (11) when a rotating shaft (23) is angularly displaced, the boot comprising the bellows member (11) with large and small diameter mounting members (12, 13) is structured such that a first mountain portion (111) nearest the large diameter mounting member (12) raises from the large diameter mounting member (12), a length (L1) between a top (111a) of the first mountain portion (111) and a bottom (111b) at the large diameter mounting member (12) side is not more than a length (L2) between the inner peripheral position of the bottom (111b) and an end portion (21b) of an outer ring (21) at the rotating shaft (23) side, and a first valley portion (112) adjacent to the first mountain portion (111) is positioned at the rotating shaft (23) side from the end part (21b).
