IN-VEHICLE ELECTRICAL JUNCTION BOX AND CONNECTION STRUCTURE BETWEEN ELECTRICAL JUNCTION BOX UNIT AND ELECTRONIC CONTROL UNIT OF IN-VEHICLE ELECTRICAL JUNCTION BOX

摘要

In an electrical junction box for a vehicle, pairs of first and second protruding portions (26, 27) are provided on the side surfaces of an electrical junction box unit (4) having a substantially rectangular box shape, the side surfaces being faced to each other. The pairs of first and second protruding portions (26, 27) are arranged so as to be symmetric with respect to the central axis extending between the pairs of first and second protruding portions (26, 27). The pair of first protruding portions (26) and the pair of second protruding portions (27) are arranged with different gaps (Wl, W2) therebetween. The electrical junction box unit (4), to which the electronic control unit (2) is assembled, is provided with supporting structure portions which are vertically provided so as to face each other, receive and support the electronic control unit (2). The supporting structure portions are provided with a pair of first lock mechanisms that is provided in the first guide grooves (28) which guide the protruding portions (26), and that locks the pair of first protruding portions (26, 27). Accordingly, it is possible to be provided the electrical junction box capable of improving the handling of wire harnesses even though the position of a driver's seat is changed to the left or right side.
