PROBLEM TO BE SOLVED: To readily remove a floor installation leg from a main body by controlling a control lever through a bias means so that a bias force works in a direction to allow an engaging portion to engage with the main body and rotating an operating portion with a downward force against the force of the bias means. SOLUTION: In mounting a main body 1 on a leg 18, the leg 18 is placed on a floor surface followed by placing the main body 1 on the leg 18, by which a control lever 20 is rotated against the spring force of a torsion spring 23. An engaging protrusion 19 of the leg 18 is inserted into an engaging recess of the main body 1 to limit the horizontal movement of the main body 1. When a rib 15 of a bottom surface 1c of the main body 1 comes into contact with the upper surface of the leg 18, a claw 21 of the control lever 20 is engaged with an engaging hole 17 by the spring force of the torsion spring 23. Thus, mounting of the leg 18 on the main body 1 is completed and setting at a given place is finished. In this way, mounting work of the leg 18 to the main body 1 is simplified and mounting workability is improved. |
