PROBLEM TO BE SOLVED: To suppress the cost of a top wall reinforcing beam and prevent the slippage of the beam and opening of a joint between top wall panels due to an increase in pressure in a cabinet. SOLUTION: A mounting fitting, which mounts a top wall reinforcing beam 2 prepared by joining a plurality of lightweight lip-shaped channel steel beam material 20 into a straight line on a top wall panel 4, includes a right side mount member 31 and a left side mount member 32. The member 31 is formed from a right side mount member body 31a comprising a horizontal part 311 to be secured to the top surface of the panel 4 and an inverted U-shaped part 312 across a lower lip 25 and a wedge 31b to be driven into between the lip 25 and the left side wall of an inverted U-shaped part 312. The member 32 comprises a lower side horizontal part 321 to be secured to the top surface of the panel 4, a vertical part 322 which is laid on the left side surface of a web 23 and fixed by a tapping screw 11, an upper side horizontal part 323 laid on the upper surface of an upper flange 22, and a hanging part 324 laid on the right side surface of an upper lip 21.
