The respective vertical frames 51 are provided in pairs in the vehicle width direction. The vehicle front side end portions of the respective vertical frames 51 can be fixed to the lower surface of the floor panel 101.
The front side cross frames 53 and the rear side cross frames 54 (hereinafter, collectively referred to as " cross frames 53, 54") are provided in pairs in the vehicle longitudinal direction. The lateral frames 53,54 connect the vehicle longitudinal direction intermediate portions of the longitudinal frames 51 to each other.
A motor unit 4 is fixed to the sub-frame 5. The motor unit 4 is surrounded by each of the vertical frames 51 and each of the lateral frames 53, 54. The outer surface of the motor unit 4 on the vehicle front side is fixed to the front side cross frame 53, and the outer surface on the vehicle rear side is fixed to the rear side cross frame 54. The vehicle rear side end portion of the motor unit 4 is located further toward the vehicle front side than the vehicle rear side end portion of the rear side cross frame 54 in plan view. The motor unit 4 is disposed at a substantially central portion of the sub-frame 5 in the vehicle width direction. The connection portion 42 is not covered with the sub-frame 5 (rear side cross frame 54) as viewed from the vehicle rear side.
The rear side cross frame 54 has a concave portion 541 recessed downward in its upper surface portion.
The concave portion 541 is provided in a part of the rear side cross frame 54 in the vehicle width direction, and more specifically, in a region on the vehicle front side of the rear side cross frame 54 at substantially the center in the vehicle width direction. A part of the motor unit 4 on the vehicle rear side and the lower side is disposed in the recess 541. The sub-frame 5 covers the lower portion of the motor unit 4 from the vehicle rear side and below.
The cable 6 supplies electric power to the motor unit 4. The cable 6 has a plug portion 61 at one end in the longitudinal direction thereof. The cable 6 can be connected to the motor unit 4 (the connection portion 42) via the plug portion 61.

The plug portion 61 has an abutting portion 611, and when the plug portion 61 and the connection portion 42 are connected to each other (hereinafter, simply referred to as "cable connection state"), the abutting portion 611 abuts against the connection portion 42. The contact portion 611 has a plate shape, and in detail, has a substantially triangular plate shape. The plug portion 61 is connected to the connection portion 42 such that one vertex of the substantially triangle of the contact portion 611 faces in the directly downward direction. In the cable connection state, the plug portion 61 is in a state in which the plate surface of the contact portion 611 contacts the connection portion 42. The area occupied by the connection portion 42 on the motor unit 4 (the housing 41) is an area where the motor unit 4 is in contact with the contact portion 611 in the cable connected state, as viewed from the vehicle rear side.
A bolt hole 612 that is provided to penetrate in the plate surface direction of the abutting portion 611 and through which the bolt B can be inserted is provided at the lower portion of the abutting portion 611. In the connection portion 42, a bolt hole (not shown) capable of fixing the bolt B is provided at a position corresponding to the bolt hole 612 in the cable connection state. Therefore, the plug portion 61 (the abutting portion 611) and the connecting portion 42 can be fixed by the bolt B in the cable connected state.
In the cable connected state, the cable 6 extends from the vehicle front side toward the vehicle rear side, and then turns back toward the vehicle front side to reach the connection portion 42. The middle portion of the cable 6 in the longitudinal direction is disposed along the vehicle right side of the motor unit 4.
The plug portion 61 is bendable in the longitudinal direction of the cable 6. In the cable connected state, the cable 6 is bent near the end portion on the side connected to the connecting portion 42, and in detail, the plug portion 61 is bent. Both ends of the plug portion 61 in the longitudinal direction of the cable 6 face in the vehicle front side direction. Thereby, the cable 6 can be easily switched in direction in the vicinity of the connection portion 42. The above-described bent portion of the plug portion 61 is located on the vehicle rearmost side in the cable 6. The vehicle rear side end portion of the cable 6 (plug portion 61) is located further toward the vehicle front side than the vehicle rear side end portion of the rear side cross frame 54.
The connection portion 42 may be provided at the vehicle left end portion of the vehicle rear side outer surface portion of the motor unit 4 (the case 41). In this case, the connection portion 42 may be provided toward the left oblique rear of the vehicle. In the cable connected state, the cable 6 is bent at the plug portion 61, and a longitudinal middle portion of the cable 6 is disposed along the vehicle left side of the motor unit 4.
The connection portion 42 and the cable 6 are not covered by the rear side cross frame 54 from the vehicle rear side. Thus, the user can easily approach the hand or tool to the vicinity of the connection portion 42 or the cable 6 through the space surrounded by the floor panel 101 and the rear side cross frame 54.
As described above, the peripheral structure 1 of the motor unit of the above embodiment includes: a motor unit 4 disposed below the floor panel 101 of the electric vehicle 100 and driving rear wheels of the electric vehicle 100; a sub-frame 5 extending in the vehicle width direction and supporting the motor unit 4; and a cable 6 connected to the motor unit 4; the motor unit 4 includes a connection portion 42, and the connection portion 42 is provided on an outer surface portion of the motor unit 4 on the vehicle rear side toward the vehicle rear side, and connects the cable 6, and the vehicle rear side end portion of the motor unit 4 and the vehicle rear side end portion of the cable 6 are both located on the vehicle front side than the vehicle rear side end portion of the sub-frame 5 in plan view, and the connection portion 42 is not covered with the sub-frame 5 when viewed from the vehicle rear side.
Thus, the vehicle rear side end portion of the motor unit 4 and the vehicle rear side end portion of the cable 6 are both located further toward the vehicle front than the vehicle rear side end portion of the rear side cross frame 54, and therefore the motor unit 4 and the cable 6 can be protected from collision from the vehicle rear side.
Since a hand or a tool can be inserted from above the rear side cross frame 54, when bending of the cable 6 is adjusted or the cable 6 and the connection portion 42 are fixed by the bolt B, the hand or the tool can be easily brought close to the vicinity of the cable 6 or the connection portion 42, and thus workability in cable connection can be improved.
