It is led out to the left through the lower cutout 27 of the table 20 in the figure.

On the other hand, a connector 50
Is attached. As the procedure, the clamp 30 is attached to the mounting base 20. As shown in FIG. 3, the clamp 30 is oriented so that the extension base 44 faces rearward, and as shown by the arrow in the figure, the locking part 31 is attached to the mounting hole 23 of the top plate 21 of the mounting base 20. Inserted inside. The clamp 30 is inserted with the front end side of the hanging plate 36 inserted into the groove 25 of the mounting hole 23 and the fitting projection 37 on the rear end side corresponding to the semicircular portion 26 at the rear end of the mounting hole 23, At the same time, the pair of elastic locking pieces 40 deflect and deform so as to close the straight side edge of the mounting hole 23 and close, and deform so that the umbrella portion 35 hits the front edge of the mounting hole 23 and is crushed.

When the insertion force is removed at an appropriate point, the clamp 30 tends to come out above the mounting hole 23 by the restoring elastic force of the umbrella portion 35. One is locked to the straight edge on the back side of the mounting hole 23, so that the mounting hole 23 is mounted in a retaining state as shown in FIG. At this time, the fitting protrusion 37 on the rear end side of the hanging plate 36
Fits into the semicircular portion 26 at the rear end of the mounting hole 23, and in particular, the front end side of the hanging plate 36 is tightly inserted into the groove 25 formed at the front end side of the mounting hole 23, so that the clamp 30 is strong. It is stopped. At this time, the upper end of the fall prevention rib 61 erected on the rear side of the mounting base 20 is located almost directly below the bottom surface of the extension base 44.

Specifically, the guide plate 45 of the clamp 30 is inserted into the groove of the pair of rails 56 on the connector 50 side, and the connector 50 is pushed in so as to slide relatively. When approaching the end of pushing, the lock projection 59 on the connector 50 side enters the inlet 48 of the clamp 30 and then rides on the bridge 47. When the rails 56 are pushed by the proper amount, the rear end of the rail 56 abuts against the stopper 46 on the clamp 30 side, and the front end of the guide plate 45 abuts against the stopper 57 on the rail 56 side, so that the pushing is stopped. At that time, as shown in FIG. The connector 50 is attached in a state where the connector 50 is prevented from falling forward by the locking projection 59 being locked to the locking edge 49.

During insertion of the connector 50, the clamp 3
0 may cause the front end to fall obliquely upward while elastically deforming the umbrella portion 35, but the bottom surface of the extension base 44 is received by the upper end of the fall prevention rib 61, whereby the inclination is minimized, In addition to the fact that the clamp is not rotated as described above, the clamp 30 is firmly attached in the attachment hole 23 without rattling.
The work to insert into is done smoothly. Note that an electric wire (not shown) drawn from the rear surface of the connector 50 may be merged with any of the electric wires W1 to W3 and led out to the left side of FIG.

As described above, according to the present embodiment,
