Further, the vertical plate 72a has two first through holes 72c that penetrate in the front-rear direction D2.

The bracket 73 is a substantially L-shaped member when viewed in the front-rear direction D2, and has one second through hole 73a and two third through holes 73b penetrating in the width direction D1. The bracket 73 may include ribs 73c.

The load measuring device 8 can measure the load when a measuring shaft 81 provided at the front end is pressed against an object to be measured, and may be, for example, a force gauge (also referred to as a push-pull gauge).

The position adjustment mechanism 9 includes a pair of guide plates 91 that guide the load measuring device 8 in the width direction D1, a push plate 92 that presses the rear end of the load measuring device 8, and a moving mechanism 93 that moves the push plate 92. You may be prepared.

The pair of guide plates 91 sandwich the load measuring device 8 from both sides in the front-rear direction D2. However, a gap exists between the guide plate 91 and the load measuring device 8 so that both can slide against each other. The guide plate 91 has two bolt-like members 91a, and the bolt-like members 91a are fixed to the first through holes 72c of the U-shaped plate 72 with nuts 91b.

The nut 93b is fixed at the position of the fourth through hole 93d. The rectangular plate 93c and the bracket 73 are connected by bolts 93f that pass through the fifth through hole 93e and the third through hole 73b. Thereby, the nut 93b is removably fixed to the main body 7 via the rectangular plate 93c.

The jack bolt 93a is inserted through the second through hole 73a and the fourth through hole 93d, and is screwed into the nut 93b. The tip of the jack bolt 93a protrudes beyond the nut 93b.

The push plate 92 pushed by the jack bolt 93a can push the load measuring device 8 toward the skirt panel 4e.

Since the jack bolt 93a changes the amount of protrusion from the nut 93b according to the amount of rotation, the jack bolt 93a presses the load measuring device 8 toward the skirt panel 4e with the amount of movement that corresponds to the amount of rotation, thereby changing the width direction D1 relative to the main body 7. The position can be changed. Moreover, since the movement of the jack bolt 93a is restricted by the nut 93b fixed to the main body 7, the position of the load measuring device 8 in the width direction D1 can be maintained. Thereby, the position adjustment mechanism 9 can accurately adjust the position of the load measuring device 8 in the width direction D1 with respect to the main body 7. Note that the jack bolt 93a may be locked at a desired position by a lock nut 93g.
