CONSTITUTION: An outer shell layer 2 is formed by a fibre reinforced plastics, and a frame body 1 is formed by filling a foaming material 3 into the shell layer 2. A gut hole 4 is formed at the frame body 1. A protector with a valley 6 formed some holes 5 and hill 7 at both sides of the valley 6 is mounted along a surrounding face of the frame body 1 so as to agree the hole 5 with the gut hole 4. A grommet 9 for protecting the gut except the protector 8 is inserted into the hole of the protector 5 and the gut hole 4 along on the valley 6 of the protector 8 in a shape of a belt of a gut settling element 12 jointed with a belt 10. By settling the gut onto the frame body 1, the belt 10 is fixed the protector 8 at the surrounding face of the frame body 1.
