  Next, by further tightening the joining screw 10, the upper protrusion 81c of the tip protrusion 81e contacts the inclined surface 72f, and then the tip protrusion 81e moves to the waterproof pan 2 side along the inclined surface 72f. If the joint screw 10 is continuously tightened, the two bent portions 81 move toward the lower side of the groove forming portions 2b of the two waterproof pans 2, respectively. Then, by tightening the joining screw 10, the tip protrusion 81e is detached from the inclined surface 72f, and the upper edge of the tip protrusion 81e moves to a position facing the groove forming portion 2b, so that the lower member 8 is moved to the upper member 7. Fixed to. At this time, the groove forming portions 2 b of the two waterproof pans 2, that is, the end portions are sandwiched between the upper connecting portion 71 of the upper member 7 and the bent portion 81 of the lower member 8. When the joining screw 10 is tightened and the lower member 8 is fixed to the upper member 7, the bent portion 81 side of the flat plate portion 82 of the lower member 8 is lower than the portion where the joining screw 10 is screwed. By forming the lower member 8 so that the flat plate portion 82 is warped, the groove forming portion 2b is more firmly held.

  According to the connecting unit 3 of the present embodiment, the lower member 8 attached by the joining screw 10 entering from the upper side to the lower end of the lower protruding portion 72 provided on the lower side of the upper member 7 is 2 together with the lower protruding portion 72. Inserted between the groove forming portions 2b forming the ends of the two waterproof pans 2 and abutting against the inclined surface 72f by tightening the joining screw 10, and the groove protruding from the inclined surface 72f to the side of the lower projecting portion 72 Since it is guided to a position facing the forming portion 2b in the vertical direction, it is bridged between the groove forming portions 2b of the waterproof pan 2 by covering the space between the groove forming portions 2b by tightening the joining screw 10 from above. It is possible to easily connect the two waterproof pans 2 by sandwiching the groove forming portion 2b of the waterproof pan 2 together with the upper connecting portion 71.

  Further, since the lower member 8 is brought into contact with an inclined surface 72f that is inclined from the center side between the two groove forming portions 2b toward the lower side of each groove forming portion 2b, the joining screw 10 is provided from above. When it is pulled up by tightening, the tip protrusion 81e of the lower member 8 can be more reliably projected to the side of the lower protrusion 72 along the inclination of the inclined surface 72ff.

  Further, when the lower member 8 is inserted between the two groove forming portions 2 b together with the lower protruding portion 72, the lower member 8 is disposed within a range narrower than the width between the two groove forming portions 2 b, and the lower protruding portion 72 is connected by the joining screw 10. Therefore, it is not necessary to hold down the lower member 8, and it can be easily inserted between the two groove forming portions 2b by work from above.

  Further, the temporarily fixed lower member 8 protrudes on both sides of the lower projecting portion 72 and faces each groove forming portion 2b of each waterproof pan 2, so that by tightening one joining screw, two It is possible to sandwich the waterproof pan 2.

Further, since the upper member 7 is provided with a lower extension portion 72d that supports the lower member 8 to which the temporarily fixed joining screw 10 is loosened, even if the temporarily secured joining screw 10 is detached from the lower member 8. Even so, it is possible to support the lower member 8 by the lower extension portion 72 d and prevent the lower member 8 from falling off the upper member 7.
Further, it is possible to provide a connected bus unit 1 that can easily connect the two waterproof pans 2 by operating the joining screw 10 from above.
