[0045]
Thus, the mat material 12b of a portion corresponding to the linear section 14b, by forming a high of 30 times of 40 times the foamed rate foamed polyethylene foam, it is possible to reduce the material cost of the mat 12. In particular, the area of the mat member 12b corresponding to the straight portion 14b occupies more than half the area of the mat 12, so that the material cost can be greatly reduced.
[0046]
Further, the U-turn portion 14a, the mat member 12a of a portion corresponding to 14c, the 12c, by forming at 20-fold lower foamed polyethylene foam having foamed rate of the mat in the portion corresponding to the U-turn portion 14a, 14c 12 flexibility does not become excessive. Furthermore, since the 20-fold foamed rate foamed polyethylene foam of the pressing force is strong, U-turn portion 14a of the hot water pipe 14, 14c is never jump out of the mat 12 buried trench within 38.
