Patent attributes
A hose clamp has an annular clamp body to be fitted on a clamp mounting portion of an end portion of a hose, and the clamp body is configured so as to tighten the clamp mounting portion by diametrically contracting the clamp body. A holding structure of the hose clamp has an anti-rotation engaging portion on the clamp body, an engaging holder portion on the hose, and a deformation restraining mechanism for restraining deformation of the hose when the clamp body tightens the clamp mounting portion. The engaging holder portion engages with the anti-rotation engaging portion in a circumferential direction when the clamp body is fitted on the clamp mounting portion. The deformation restraining mechanism restrains that the anti-rotation engaging portion is pressed against the engaging holder portion and thereby the hose is deformed via the engaging holder portion.
