This concludes the description of the configuration of the present embodiment. Next, the effects of the present embodiment will be described. First, the motor accommodating tray 10 is placed on the conveyance container 70 in an empty state. Then, the motors 90 are accommodated in the motor accommodating tray 10 in an orientation in which they are rotated by 180 degrees with respect to each other.

When the motor 90 is arranged on the motor receiving tray 10 , the bulging parts 25 , 30 , 35 , and 40 support the motor main body part 90A and restrict the movement of the motor main body part 90A in the horizontal direction. Here, the part which supports the motor of the conventional tray has a structure manufactured by adhering to the tray main body. On the other hand, since the motor accommodating tray 10 of this embodiment is integrally formed by vacuum forming, it is possible to suppress the labor required for manufacture.

In addition, two motors 90 can be arranged in one motor accommodating tray 10, the two motor arrangement regions R are formed to be rotationally symmetrical, and the sub arrangement region R2 is along one side of the main arrangement region R1 of the adjacent motor arrangement region R, so The free space is reduced and the containment efficiency is improved. Also, the front ends of the wire harnesses are disposed away from each other, thus preventing the wire harnesses from being entangled with each other.

In addition, by forming the recessed portion 14 in the flange portion 13 of the motor receiving tray 10 , the side wall 14B described above functions as a rib, thereby enhancing the strength of the motor receiving tray 10 . In addition, since the recessed portion 14 has a groove shape and one end 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.

Furthermore, when the motor accommodating tray 10 is placed on the transport container 70, the flange portion 13 is supported by the support frame 73, so that the motor accommodating tray 10 is prevented from being crushed by the flange portion 13 or the tray side wall 12 from falling over. deformed. Moreover, since the support frame 73 of the conveyance container 70 abuts the recessed part 14 of the flange part 13 from the back side, the reinforcement part is supported, and the support of the flange part 13 becomes more stable.

In addition, when the motor accommodating tray 10 is placed on the transport container 70, the central groove portion 50 and the side groove portion 51 of the motor accommodating tray 10 are respectively engaged with the central protrusions 74 and the side protrusions 75 of the transport container 70. In this way, the displacement of the motor receiving tray 10 with respect to the transport container 70 and the shaking in the front-rear direction and the left-right direction are restricted. Here, instead of providing the center protrusions 74 and the side protrusions 75 , the support frame 73 of the transport container 70 may be configured to be able to abut on the tray side walls 12 of the motor storage tray 10 to restrict the motor storage tray. However, the smaller the reference size is, the smaller the tolerance can be. Therefore, the clearance between the center groove portion 50 and the side groove portion 51 and the center protrusion 74 and the side protrusion 75 is smaller than that between the support frame 73 and the tray side wall. The play between the 12 is more easily reduced, so that the shaking of the motor receiving tray 10 is suppressed. In addition, since the central groove portion 50 and the side groove portion 51 also serve as the central ridge portion 20 and the first bulging portion 25 , there is no need to provide a protruding portion for the central groove portion 50 and the side groove portion 51 , and there is no need for the arrangement of the motor 90 . to influence. In addition, since the central protrusion 74 and the side protrusions 75 are rectangular, 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 center protrusion 74 are sandwiched by the pair of inner side surfaces of the center groove portion 50 (the inner side surfaces of the pair of side walls 20B of the center ridge portion 20 ), the rotation of the motor accommodating tray 10 is further restricted. .
