Claims

[Scope of Claim for Utility Model Registration] (1) A hose, an inner cylindrical fitting housed in the hose, and a hose that is fitted onto the hose at a position corresponding to the inner cylindrical fitting and is pressed radially inward to fit the hose. In a hose intermediate holder fixing structure consisting of an intermediate holder consisting of an outer cylindrical fitting that holds the hose between an inner cylindrical fitting and a clamp secured to the outside of the outer cylindrical fitting, The cylindrical metal fitting has a small end diameter portion extending in the circumferential direction that is press-deformed in the axial direction at both end portions at a predetermined interval in the center, and a large-diameter center portion that is not press deformed and extends in the circumferential direction. The clamp has a non-engaging portion in which a portion corresponding to the large center diameter portion of the outer cylindrical metal fitting is a recess or a hole, and a non-engaging portion on both sides of the non-engaging portion and an outer circumferential surface of each small end diameter portion. It has a band-shaped engaging portion that is abutted and locked, and both side surfaces of the large center diameter portion of the outer cylindrical fitting and opposing side surfaces of the engaging portion of the clip are in contact with each other so that they are axially relative to each other. A hose intermediate holder fixing structure characterized by having a configuration that prevents movement. (2) The center part of the outer cylindrical metal fitting further has a small center diameter part extending in the outer circumferential direction whose center is pressed and deformed in the axial direction, and there are one large center diameter part on both sides of the small center diameter part. The hose intermediate holder fixing structure according to claim 1, which is formed in two pieces.
