  Next, a procedure for installing the power transmission device 20 in the stop space SS of the vehicle 50 will be described with reference to FIGS. 5 to 9.

  When installing the power transmission device 20 in the stop space SS of the vehicle 50, first, one positioning sheet 100, four height adjusting pole units 200, and one laser irradiation device 300 are prepared. Furthermore, a plurality of basic spacers 400 and adjustment spacers 405 for tires (wheels) and spacers 410 for power transmission devices 20 are prepared.

Furthermore, the spacer 410 for the power transmission device 20 is formed in a plate shape having a surface area slightly larger than the bottom area of the power transmission device 20.

  Prior to the placement of the power transmission device 20 in the stop space SS, the positioning sheet 100 described above is laid in the stop space SS. The positioning sheet 100 takes into consideration the ease of getting on and off of the vehicle 50 and the ease of loading and unloading through the gate so that interference between the vehicle 50 and structures around the stopping space SS is suppressed. However, it is laid in the stop space SS. After the positioning sheet 100 is laid in the stop space SS, the base 201 of the height adjusting pole unit 200 is installed on each tire display portion 102 of the positioning sheet 100 and the opening of the positioning sheet 100 The power transmission device 20 is installed in 101. Further, the laser irradiation device 300 (pedestal 301) is installed on the power transmission device 20 so as to be positioned at the center of the power transmission coil 21.

  When the height adjusting pole unit 200 is disposed on each tire display unit 102, the first positioning line 201x of the pedestal 201 is aligned with the center line of the tire display unit 102 in the vehicle front-rear direction, and the tire display unit 102 The second positioning line 201y of the base 201 is aligned with the center line in the vehicle width direction. Thereby, the pole unit 200 for height adjustment (base 201) can be arrange | positioned in the center of the tire display part 102, ie, the center of the contact surface (wheel installation surface) of the tire in the stop space SS.

The amount of deviation between the irradiation position and the reference laser irradiation position 202a is read from the scale 202s. Then, after stopping the laser irradiation from the laser irradiation apparatus 300, the height adjusting pole unit 200 or the laser irradiation in which the difference between the actual laser irradiation position and the reference laser irradiation position 202a exceeds a predetermined threshold value. A basic spacer 400 or a spacer 410 is disposed below the apparatus 300.

  That is, in any of the height adjusting pole units 200, when the amount of deviation exceeds a threshold value and the actual laser irradiation position on the pole 202 is positioned above the auxiliary plate 203, FIG. As shown, a basic spacer 400 is disposed below the height adjusting pole unit 200 (pedestal 201), and an adjusting spacer 405 is further disposed below the basic spacer 400 if necessary according to the amount of displacement. . Further, in the plurality of height adjusting pole units 200, when the above-mentioned deviation amount exceeds the threshold value and the actual laser irradiation position on the pole 202 is located below the auxiliary plate 203, it is shown in FIG. As described above, the number of spacers 410 corresponding to the amount of deviation is arranged below the laser irradiation apparatus 300 (base 301). At this time, the basic spacer 400 and the like may be directly installed on the surface of the stop space SS with the positioning sheet 100 being turned up. At this stage, the positioning sheet 100 may be removed.

The inclination of the pole 202 and the support rod 302 is adjusted so as to be included. Further, each height adjusting pole unit 200 is irradiated with laser from the laser generator 303 of the laser irradiation apparatus 300, and the actual laser in the pole 202 is provided for each height adjusting pole unit 200 as described above. The amount of deviation between the irradiation position and the reference laser irradiation position 202a is read from the scale 202s. In this case, if necessary, an adjustment spacer 405 or a spacer 410 is added according to the amount of deviation. At this time, adjustment using a fine adjustment spacer (not shown) may be performed so that the amount of deviation is as small as possible (so as to be equal to or less than the threshold value). Then, after the number of the basic spacers 400, the adjustment spacers 405, and the spacers 410 is determined, the basic spacers 400 and the like are fixed to the stop space SS using an anchor or the like. Further, the power transmission device 20 is fixed on the stop space SS or the spacer 410. Thereby, installation of the power transmission apparatus 20 in the stop space SS is completed.
