る。There is another conventional technique in which a reinforcing material is embedded in the inside of the annular concave portion and the inside of the insertion piece in FIG. The reinforcing material for the annular concave portion is formed by bending a wire in a bellows shape to form a flat plate-like surface, and forming the plate-like member into a concave shape and burying the concave portion on the outer peripheral side of the annular concave space. The reinforcing material of the insertion piece is formed by bending a wire into a bellows shape, forming a plate shape, and burying the wire in the center of the insertion piece so as to lie in the tip direction.

ス部とは機械的に係止するので、ブーツの接合した分割
面が外力を受けても離間するのを効果的に防止できる。The boot according to the present invention has a configuration in which a male connecting portion made of the same material is inserted into a female connecting portion made of a hard material and elastic, and the engaging portion is locked by the engaging female portion. This makes it easy to insert, and since the locking portion and the engaging female portion are mechanically locked, it is possible to effectively prevent the split surface to which the boot is joined from separating even if it receives external force. Can be prevented.

強化される効果を奏する。In the boot according to the second aspect of the present invention, the elastic locking portion is locked to the engaging female portion, and the insertion portion does not strongly contact the receiving portion, so that only the locking portion is engaged. It can be pressed against the female part. For this reason, even if the first division surface and the second division surface are not formed on the same plane to some extent, the first division surface is not limited to the first division surface.
The locking portion can be pressed against the engaging female portion so that the divided surface and the second divided surface are joined. As a result, the first divided surface and the second divided surface are hermetically bonded to each other, and the sealing force of the divided surfaces is enhanced.
