Abstract
The invention includes a base ( ) provided with pairs of fitting hole ( ), two each of which are spaced apart and situated facing each other so as to constitute a pair. A pair of rotary shaft portions ( ) of each first leg member ( ) are rotatably fitted in each pair of fitting holes ( ). The two rotary shaft portions ( ) are formed on the outer surface of the upper end portion of each first leg member ( ) as an integral body therewith so as to extend coaxially. A second leg member ( ) is inserted in each first leg member ( ) in such a way that the distance by which the second leg member ( ) projects from the first leg member ( ) can be adjusted. As the top end face of each second leg member ( ) can be positioned flush with the top end face of the associated first leg member ( ), the invention is capable of improving the telescopic extension ratio of the legs.
