The X-side elastic portion 93a presses the outer wall portion on the -X direction side of the plug connector 76a in the +X direction by an elastic force. The outer wall portion on the -X direction side of the plug connector 76a receives the elastic force of the X-side elastic portion 93a.

The control unit 89a controls the position of the plug connector 76a in the X direction with respect to the opening 86a using the elastic force of the X side elastic portions 92a and 93a. For example, when a force in the -X direction is applied to the plug connector 76a, the X-side elastic portion 92a extends in the -X direction, and the X-side elastic portion 93a contracts in the -X direction. Therefore, the plug connector 76a moves in the -X direction in a predetermined space formed between the outer wall portion of the plug connector 76a and the wall portion 88a. When a force in the +X direction is applied to the plug connector 76a, the X-side elastic portion 92a contracts in the +X direction, and the X-side elastic portion 93a extends in the +X direction. Therefore, the plug connector 76a moves in the +X direction in a predetermined space formed between the outer wall portion of the plug connector 76a and the wall portion 88a.

Further, on the +Y direction side of the control unit 89a, as shown in FIG. 13, four Y-side elastic portions 94a are formed.

Further, the plug connector 76b includes a plurality of contacts (not shown) and a plug cover 65b (see FIG. 9). These structures are line symmetrical with respect to the center line of the plug mating connector 75 in the Y-axis direction, and are identical to the structures of the plurality of contacts 85a, 59a and the plug housing 65a, respectively. Further, on the +Z direction side of the circuit board 82b, one end of the plurality of cables 83b is fixed by welding or the like. Each of the plurality of cables 83b is electrically connected to a plurality of contacts 85b disposed on the +Z direction side of the plug connector 76b, respectively. Further, on the -Z direction side of the circuit board 82b, one end of the plurality of cables 84b is fixed by soldering or the like. Each of the plurality of cables 84b is electrically connected to a plurality of contacts (not shown) disposed on the -Z direction side of the plug connector 76b.

Here, since one ends of the plurality of cables 83a and 83b are fixed to the circuit boards 82a and 82b, the circuit boards 82a and 82b to which the plug connectors 76a and 76b are attached are the first ones for holding one end of the plurality of cables 83a and 83b. The holding unit functions. The details of the first holding unit will be described later.

Next, the structure of the rear cover 81 will be described. As shown in FIG. 9, the rear cover 81 is attached and fixed to the front cover 79, and supports the plug connectors 76a and 76b from the -Y direction side.
