By making the material of the inner members 13 and 17 different from the material of the outer members 14 and 18, it is possible to easily cope with diversification of the external design,
Moreover, it is easy to reduce the weight and cost. That is, for example, if the relatively thick and inexpensive inner members 13 and 17 and the relatively thin and expensive outer members 14 and 18 are combined to form a multi-layer structure, the inexpensive appearance design can be improved.
