And in the state which the back surface 32B of the protrusion part 32 contact | abutted to the front surface of the side plate part Pc, the protrusion part 32 is located in the lip part Pd side from the centerline of the width direction of the side plate part Pc in lightweight shape steel P. Yes.

  For this reason, when the light-weight shaped steel material P is grasped by hand from the back plate part Pb side, the protruding portion 32 is disposed at the place where the finger (thumb) is located. It can be grasped and the surface 32A of the protruding portion 32 can be pressed with the thumb toward the side plate portion Pc. When the thumb 32 presses the front surface 32A of the protruding portion 32, the back surface 32B of the protruding portion 32 is pressed against the side plate portion Pc, and the protruding portion 32 is sandwiched between the thumb and the side plate portion Pc.

  As shown in FIG. 5, the projecting portion 32 is formed in a flat plate shape as a whole, and is formed in a U shape in front view. That is, the entire protrusion 32 has a flat plate shape so that when the surface 32A is pressed toward the side plate portion Pc (another wall portion), the protrusion 32 itself does not rotate on the side plate portion Pc with its own axis of rotation. Is formed. Moreover, since the protrusion part 32 is connected with two places with respect to the front-end surface 31a, the protrusion part 32 is contact | abutting in the position away in the standing direction of the lightweight shaped steel material P with respect to the side-plate part Pc. In addition, when the protrusion 32 presses the surface 32A toward the side plate portion Pc (another wall), the protrusion 32 rotates in the direction toward the lightweight steel material P of the pedestal main body 31 with the protrusion 32 as a rotation center. It is formed in a size that prevents movement and rearward movement of the lightweight steel P. For this reason, the pedestal main body 31 rotates or rotates toward the opening Pa in the lightweight steel P by pressing the protruding portion 32 with the thumb and sandwiching the protruding portion 32 between the thumb and the side plate portion Pc. It moves and is prevented from entering the inside of the opening Pa.

  Then, the mounting base 30 is held by the lightweight steel member P so that the front end face 31a of the base main body 31 is positioned on substantially the same plane as the front surface of the side plate portion Pc. As shown in FIG. 6A, the fixing hole 34 on the projecting portion 32 side in the mounting base 30 is at a position facing the lip portion Pd.

Here, the fixing hole 34 is formed through the pedestal main body 31. For this reason, when the screw N is inserted into the fixing hole 34, the screw N is brought into contact with the inner surface of the fixing hole 34 and is prevented from being tilted. Therefore, the workability of screwing the screw N guided to the lip part Pd by the fixing hole 34 into the lip part Pd can be further improved.

  And, by inserting the screw N into the lip portion Pd, a large force that slides in the length direction of the runner R acts on the lightweight steel P, but the lightweight steel P is gripped by hand. The lightweight shape steel P is prevented from sliding. Therefore, when the screw N is screwed in, the mounting base 30 is held in a predetermined position by the protrusion 32 being sandwiched. Furthermore, since there is no sliding movement of the light-weight shaped steel material P, the fixing work of the mounting base 30 to the light-weight shaped steel material P is easily performed.
