PROBLEM TO BE SOLVED: To solve the problem of inclining even a deck fixed to a support plate, since the support plate also becomes an inclined attitude, when a base inclines in response to an inclination of a rooftop floor surface, when juxtaposing conventional posts on the rooftop floor surface, since the rooftop floor surface normally inclines a little. SOLUTION: The base 3 of a post 1 inclines along the inclined rooftop floor surface F, and since the base 3 can be operated in a predetermined range in the falling direction to the support plate 15, a bolt 13 becomes a vertical attitude. Thus, the support plate 15 can support the deck D in a horizontal attitude. COPYRIGHT: (C)2005,JPO&NCIPI
