レキシブルブーツ。 Both ends of the bellows part in the axial direction are fitted parts,
A flexible boot for a universal joint in which an annular groove is formed on the outer periphery of each fitting part to receive a tightening band for tightening and fixing the fitting part to the outer ring and drive shaft of the universal joint, respectively. The groove width of the groove is such that when the tightening band is received, both sides of the annular groove are in contact with both side edges of the tightening band at the same time, and when the flexible boot is cut in the axial direction. The cross-sectional shape of the bottom surface of at least one of the annular grooves has a flat central part and extends in an inclined manner from both sides of the central part so that the depth of the annular groove increases toward the outside of the annular groove. A flexible boot characterized by having a trapezoidal shape having both sides.
