  As shown in the plan view of FIG. 3, the inspection surface plate 10 is a rectangular horizontal metal plate having a vertical dimension of 70 cm and a horizontal dimension of 3 m, and has a U-shaped groove 14 in the transverse direction. Is provided. As shown in FIG. 3, the motor support 12 has a pair of left and right legs 16, 16 provided at the bottom. The leg portion 16 has a rectangular parallelepiped shape, and only the lower portion thereof is fitted into the groove 14.

(2) Attachment member Next, the attachment member used in this attachment structure is demonstrated based on FIG. The mounting member includes a bolt 20, a washer 22, and a nut 24.

  The bolt 20 is a hexagon socket head bolt and is shorter than the depth of the groove 14.

  The washer 22 is a vertically long rectangular parallelepiped with a square planar shape and an inclined bottom surface, and a long hole 26 penetrates in the vertical direction. The long axis direction of the long hole 26 is provided in the left-right direction. The upper surface of the washer 22 is a horizontal plane, and the lower surface is an inclined surface that is inclined from the right side portion toward the left side portion as described above, and the height thereof becomes thicker from the right side portion toward the left side portion. This inclination angle is 20 °. A dimension L1 of the washer 22 in the left-right direction is smaller than the width L0 of the groove 14.

  The nut 24 has a square shape in plan view and is a vertically long rectangular parallelepiped whose upper surface is inclined, and a screw hole 28 penetrates in the vertical direction at the center thereof. The upper surface of the nut 24 (the surface opposite to the lower surface of the washer 22) is an inclined surface that is inclined as described above, and its height decreases as it goes from the right side to the left side. That is, the upper surface of the nut 24 is inclined along the inclined surface of the lower surface of the washer 22. Moreover, the lower surface of the nut 24 is a horizontal surface. The dimension of the nut 24 in the left-right direction has the same width as the dimension L1 of the washer 22 in the left-right direction.

  The leg portion 16 of the motor support 12 is a horizontally long rectangular parallelepiped that can be fitted along the groove 14, and a mounting hole 18 penetrates in the longitudinal direction at the tip thereof. The attachment hole 18 is a long hole, and the long axis direction coincides with the long axis direction of the long hole 26 of the washer 22.

(3) Attachment method Next, the method to attach the motor support stand 12 to the groove | channel 14 of the test | inspection surface plate 10 is demonstrated.

  First, the motor support 12 is placed on the inspection surface plate 10.

  Next, as shown in FIG. 2, the nut 24, the washer 22, and the leg portion 16 of the motor support base 12 are fitted into the groove 14, and the lower end portion of the bolt 20 is screwed into the screw hole 28 of the nut 24. In this case, since the width of the leg portion 16 is slightly smaller than the width L0 of the groove 14, the nut 24, the washer 22 and the leg portion 16 are fitted into the groove 14. Further, the long axis side of the long hole 26 of the washer 22 is fitted along the width direction of the groove 14. That is, the inclination direction of the lower surface of the washer 22 and the inclination direction of the upper surface of the nut 24 are matched with the width direction of the groove 14 (see FIG. 2). In this state, the washer 22 and the nut 24 have a slight gap on both sides inside the groove 14, so that the leg portion 16 is movable with respect to the groove 14.

  Next, as shown in FIG. 3, since the inclined lower surface of the washer 22 and the inclined upper surface of the nut 24 are in contact with each other, when the bolt 20 is tightened, the right side portion of the nut 24 presses the right inner wall of the groove 14. (Indicated by arrow A1 in FIG. 3), the washer 22 presses the left inner wall of the groove 14 (indicated by arrow A2 in FIG. 3). Thereby, the washer 22 and the nut 24 are fixed inside the groove 14, and the leg portion 16 is also fixed. In this case, since the screw hole 28 of the nut 24 is circular, the bolt 20 moves to the right as the nut 24 moves to the right. However, since the washer 22 is a long hole 26 and the mounting hole 18 is also a long hole like the long hole 26, the washer 22 can move to the left side even if the bolt 20 moves to the right side together with the nut 24. In addition, the leg portion 16 does not move to the right and left sides, and the motor support 12 can be fixed at the same position.
