A rectangular mirror 1 is arranged on the side wall 120 of the cab 100. The four corners of the mirror 1 are supported by the four mirror mounting fixtures 2 fixed to the side wall 120 and fixed to the side wall 120.

As shown in FIG. 2, the mirror mounting device 2 for a cab according to the first embodiment includes a U-shaped fixing portion 10, a mirror pressing member 14, and a screw member 15.

The fixed portion 10 is composed of a first member 11, a second member 12, and a third member 13. The first member 11 and the second member 12 are opposed to each other with a space therebetween. The third member 13 connects the ends of the first member 11 and the second member 12 to each other.

The angle formed by the inner wall of the first member 11 and the inner wall of the third member 13 is vertical. On the other hand, the angle between the inner wall of the second member 12 and the inner wall of the third member 13 is an acute angle. Therefore, the distance between the inner wall of the first member 11 and the inner wall of the second member 12 becomes shorter as the distance from the third member increases.

The first member 11 has a through hole 11A. The side wall 120 of the cab 100 has a plurality of mounting holes 120A. A nut 17 is fixed to the outside of the side wall 120 concentrically with each mounting hole 120A. The fixing portion 10 is fixed to the side wall 120 by the screw member 16.
