The leg plate as the leg portion 16 which is continuously provided downward from both lower ends of the head portion 14 is made of a material which can elastically move in the expanding direction to a certain extent, and therefore has a certain elasticity and toughness. It is preferable to integrally fabricate a metal member having strength. For example, 3.0 mm
A metal plate having a small thickness may be bent or may be manufactured as an integrally molded product. Since the legs are erected in a bifurcated manner to support the entire base roof, it is desirable that the material be a material or a processed product capable of maintaining a considerable strength.

In this embodiment, the leg portions 16 are formed of a spring steel plate having elasticity so that the leg portions 16 can always be biased in the direction of closing and contracting each other. In short, the main body 12 is made of a metal having a certain degree of elasticity such as spring steel, stainless steel, nickel steel, nickel chrome steel or the like so that the inverted V-shaped leg 16 can be displaced in the expanding or closing direction. What is necessary is just to form integrally.
