題を有することとなった。(Problems to be Solved by the Invention) However, in such a conventional fixing method, the resin tube is fixed to each of the holding wall portions or the concave groove portions because of fixing by the clamp body formed in advance separately. Not only does the assembling work become extremely inconvenient, the workability is inevitably reduced, but also the nail walls forming the clamping walls or the mutual hooking means are defective, or the nail walls for a long period of time, Due to fatigue or vibration from engines, machines, devices, etc., the resin tube often becomes partially detached on the resin tube side, and the fixing is generally unstable. Due to the variation, the resin tube is crushed and deformed, causing problems such as obstructing the flow of the internal fluid.
