2. Description of the Related Art In general, in a right-hand drive vehicle, as shown in FIG. 4, a right electric junction box 4R is disposed between a right wheel house 2R and a dash panel 3 in an engine room 1 so that a right electric junction box 4R is positioned at a right position. The battery 5 </ b> R and the alternator 7 of the engine 6 are connected by wires 8 and 9, respectively. The electric connection box 4R is connected to devices in the room 11 by wires 10 passing through the dash panel 3.

The right electric connection box 4R is large in size to accommodate a large number of fuses, relays, and the like, and therefore, a small space between the right wheel house 2R and the dash panel 3 is effectively used. In addition, the right side (the left side in the figure) is formed to have a narrow width in order to avoid the protrusion of the right wheel house 2R, and the left side (the same as above) is formed to have a wide horizontal step shape.

There are left-hand drive vehicles in addition to right-hand drive vehicles. Left-hand drive vehicles include a left wheel house 2L in an engine room 1 as shown in FIG.
A left electric connection box 4L is arranged between the dash panel 3 and the dash panel 3, and connected to the battery 5L at the left position and the alternator 7 of the engine 6 by wires 8 and 9, respectively. For this reason,
The left electrical junction box 4L is symmetrical to the right electrical junction box 4R, and the left side (right side in the figure) is narrow to avoid the protrusion of the left wheel house 2L, and the right side (same as above) is a wide horizontal staircase. Must be formed.

[0005]

However, the same type of vehicle is different only in the position of the steering wheel.
Since various types of electric connection boxes 4R and 4L are required, there is a problem that the cost of the electric connection boxes 4R and 4L increases. As shown in FIG. 5 (B), in a left-hand drive vehicle, the right electric connection box 4R of the right-hand drive vehicle and the battery 5R at the right position are used as they are, and the left electric connection box 4L is used.
It is conceivable that the electrical connection box 4R for the right is unnecessary.
This is not preferable because the electric wire 10 connecting the vehicle and the equipment in the cabin 11 becomes very long.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a structure for taking out the power supply of an electric connection box which can be shared by a right-hand drive vehicle and a left-hand drive vehicle, thereby reducing the cost. is there.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is arranged in a right-hand drive vehicle between a right wheel house in an engine room and a dash panel, and in a left-hand drive vehicle in an engine room. In an electric connection box disposed between the left wheel house and the dash panel and connected to the battery and the alternator of the engine by electric wires, the electric connection box is disposed in a space between each wheel house and the dash panel. It is formed in a possible horizontally long rectangular shape, and a take-out portion of each of the electric wires is provided at a substantially central portion in a longitudinal direction of the electric connection box. In order to avoid this, a power supply extraction structure of an electric junction box provided downward is provided.

[0008]

According to the present invention, the electric junction box is formed not in a horizontally long staircase shape but in a horizontally elongated rectangle shape which can be arranged in a narrow space between each wheel house and the dash panel, and is formed at a substantially middle portion in a longitudinal direction. Since each unit has a power take-out part, it can share one type of electrical junction box with the same shape, and can be smoothly placed between the right wheel house and the dash panel in a right-hand drive car, and left in a left-hand drive car It can be arranged smoothly between the wheel house and the dash panel, and the wires connecting the electric connection boxes on each side and the equipment in the vehicle compartment do not become long.
In addition, by providing the outlets of the electric wires downward, it is possible to connect the electric wires to the battery and the alternator smoothly, avoiding the protrusion of each wheel house.
