Further, as shown in FIG. 13, the bottom wall 14A of the depressed portion 14 of the flange portion 13 comes into contact with the upper surface of the support frame 73, and the flange portion 13 is supported. Further, a gap is formed between the tray side wall 12 and the support frame 73.

The central groove 50 and the side groove 51 correspond to the "engagement concave portion" in the claims, and the central ridge 74 and the side ridge 75 correspond to the "engagement convex portion" in the claims. , The support frame 73 corresponds to the "flange support portion" in the claims.

This concludes the description of the configuration of this embodiment. Next, the action and effect of this embodiment will be described. First, the motor receiving tray 10 is placed on the transport container 70 in an empty state. Then, the motors 90 are received in the motor receiving trays 10 in a direction rotated by 180 degrees with each other.

When the motor 90 is arranged on the motor receiving tray 10, the bulging portions 25, 30, 35, 40 support the motor main body portion 90A and regulate the movement in the horizontal direction. Here, the conventional tray is manufactured by adhering a portion that supports the motor to the tray body. On the other hand, since the motor receiving tray 10 of the present embodiment is integrally molded by vacuum forming, it is possible to reduce the labor required for manufacturing.

Further, two motors 90 can be arranged in one motor receiving tray 10, but the two motor arrangement areas R are rotationally symmetric, and the sub arrangement area R2 is the main of the adjacent motor arrangement area R. Since it is along one side of the arrangement area R1, the empty space is reduced and the accommodation efficiency can be improved. Further, since the tips of the harnesses are arranged so as to be separated from each other, it is possible to prevent the harnesses from being entangled with each other.

Further, by forming the recessed portion 14 in the flange portion 13 of the motor receiving tray 10, the side wall 14B thereof functions as a rib, and the strength of the motor receiving tray 10 is improved. Moreover, since the recessed portion 14 has a groove shape and one end thereof is located in the middle of the width direction of the flange portion 13, the side wall 14B is also formed in the direction along the tray side wall 12, and the flange portion is further strengthened.

Then, when the motor receiving tray 10 is placed on the transport container 70, the flange portion 13 is supported by the support frame 73, so that the flange portion 13 is squashed or the tray side wall 12 is tilted, so that the motor receiving tray 10 is moved. Deformation is prevented. Moreover, since the support frame 73 of the transport container 70 comes into contact with the depressed portion 14 of the flange portion 13 from the back side, the reinforced portion is supported, and the support of the flange portion 13 becomes more stable.

Further, when the motor receiving tray 10 is placed on the transport container 70, the central groove portion 50 and the side groove portion 51 of the motor receiving tray 10 are unevenly engaged with the central ridge 74 and the side ridge 75 of the transport container 70, respectively. By doing so, the displacement of the motor receiving tray 10 with respect to the transport container 70 and the rattling in the front-rear direction and the left-right direction are regulated. Here, the support frame 73 of the transport container 70 is configured to be able to come into contact with the tray side wall 12 of the motor receiving tray 10 without providing the central ridge 74 and the side ridge 75, so that the motor receiving tray 10 is displaced. Although it may be possible to regulate, the smaller the reference size, the smaller the tolerance. Therefore, rather than the play between the support frame 73 and the tray side wall 12, the central groove portion 50, the side groove portion 51, the central ridge 74, and the side ridge 75 It is easier to make the play with the motor smaller, and the rattling of the motor receiving tray 10 is suppressed. Further, since the central groove portion 50 and the side groove portion 51 are also used for the central ridge portion 20 and the first bulging portion 25, it is not necessary to provide a protruding portion for the central groove portion 50 and the side groove portion 51, and the motor 90 is arranged. Does not affect. Further, since the central ridge 74 and the side ridge 75 have a rectangular shape, the movement of the motor receiving tray 10 is restricted at two points in the width direction, and the rotation of the motor receiving tray 10 is also prevented. In particular, since both side portions of the central ridge 74 are sandwiched between a pair of inner surfaces of the central groove portion 50 (inner surfaces of a pair of side wall portions 20B of the central ridge portion 20), the rotation of the motor receiving tray 10 is more restricted. ..
