To provide a fixture capable of fixing a plate material in various fixing directions.

A plate material fixing portion 12 for fixing the plate material is connected to a clamp portion 11 in a 360° rotatable manner. Thus, the direction of the plate material fixing portion 12 into which the plate material is inserted is freely changeable. To both cases that the plate material should be fixed in the cross direction and that it should be fixed in the vertical direction, one type of fixture 10 is applicable. As a result, although a plurality of fixtures having plate material fixing portions different in direction should be conventionally prepared, only one type of fixture 10 of this invention is sufficient for applications to eliminate the need for sorting the fixtures 10 before assembling a temporary cabin or the like. A time for preparation before assembling work is shortened, and the fixture 10 requires a smaller storage area because it is stored in one storage site.
