The connector 5 held by the housing body 7 is fitted with a mating connector (not shown) inserted from the opening on the other end side of the housing body 7, and mated terminals (not shown) housed in the mating connector. And the terminal are electrically connected.

  By fitting the connector 5 and the mating connector, for example, a device housed in the transmission case is electrically connected to a power source or a device disposed outside the transmission case.

  A bracket 11 is attached to one end side of the housing body 7 holding the connector 5 (here, the opening side into which the connector 5 is inserted), and the connector 5 side is connected to the transmission case via the bracket 11, for example. The housing body 7 is attached to the transmission case so as to be located on the inner side.

  The bracket 11 is made of a metallic material and is formed in a U shape so that the electric wire 3 can be pulled out. The bracket 11 is attached to one end side of the housing main body 7 via a plurality of locking portions 9, and is fixed to an attachment hole or the like provided in the transmission case via a fixing means, for example. Hold the case.

  In the following, the front-rear direction of the housing body 7 and the bracket 11 in FIG. 1 (FIG. 8 in the second embodiment) is the X direction, the left-right direction of the housing body 7 and the bracket 11 is the Y direction, and the housing body 7 and the bracket The vertical direction of 11 is defined as the Z direction.

The gaps L2 are set to be formed between the Y directions.

  Thus, by engaging the locking portion 9 with the gap L2 in the Y direction, the housing body 7 can move in the Y direction with respect to the bracket 11 by the gap L2, and when the connector 5 is fitted, Can have a centering function.

  Another locking portion 9 is provided between the pair of locking portions 9 and 9 having such a spring portion 13.

  The other locking portion 9 is 90 degrees with respect to the pair of locking portions 9, 9 having the spring portion 13 between the pair of locking portions 9, 9 having the spring portion 13, that is, on the outer periphery of the housing body 7. The phase is shifted. The other locking portion 9 includes a protrusion 29 provided on the housing body 7 and a hole 31 provided on the bracket 11.

  The protruding portion 29 is formed in a rectangular parallelepiped shape, and protrudes from the outer periphery of the housing body 7 in the X direction. The protrusion 29 is accommodated in the hole 31 in a state where the housing body 7 and the bracket 11 are assembled.

  The hole 31 is formed in a quadrangular shape so as to penetrate in the X direction at a position corresponding to the projection 29 of the connecting wall that connects both side walls of the bracket 11. The hole 31 is set so that the protrusion 29 is inserted in a state where the housing body 7 and the bracket 11 are assembled, and a gap L3 is formed between the protrusion 31 and the Z direction. ing. The gap between the hole 31 and the protrusion 29 in the Y direction is set to be equal to the gap L2.
