摘要

Base plates (3) are rectangular plate members. Supports (5) rise toward the base plates (3) on one side. A pair of base plate-side engaging sections (7) with which supports engage is provided to the base plate (3) at portions thereof at which the supports (5) are not provided. The engaging sections (7) correspond to the shape of the tips of the supports (5), and the tips of the supports (5) and the engaging sections (7) can be engaged with each other. The engaging sections (7) are portions in which engaging holes, engagement receiving sections, etc. corresponding to the tips of the supports are formed. Each support (5) is a tapered column having a circular truncated conical shape tapered from the base plate (3) toward the tip of the support at an angle θ in the range from 2˚ to 6˚. The wall thickness (R) of the support (5) at the tip thereof at a position directly under a bend section (27a) at the tip is greater than the wall thickness (Q) of the base bottom section located at the lower end of the support (5). It is preferable that R is, for example, 1.2 or more times greater than Q.
