  Further, the second side wall portion 521 of the second member 520 is abutted against the distal end side of the lower wall portion 514 of the first side wall portion 511. That is, the lowermost part of the wall portion covering the electric wire 509 in the electric wire protection case 500 is configured only by the lower wall portion 514 of the first member 510.

  Moreover, it has the protrusion part 521a which protrudes so that the opening by the side of the said front-end | tip part 532a among the 1st groove parts 534 may be obstruct | occluded. Therefore, the first groove 534 is closed by the protrusion 521a on the second side wall 521 side, and is opened outward by the opening 534h on the first side wall 511 side.

  In the electric wire protection case 500 configured as described above, the water that has entered the interior flows down to the first bottom wall portion 532 located at the lowest position of the lower wall portion 514 and then flows into the first groove portion 534. . Since the inside of the 1st groove part 534 inclines to the root side (1st side wall part 511 side), the water which entered the said 1st side wall part 511 is the root side (1st side wall part 511 side) according to the inclination. And flows down to the outside (below the wire protection case 500) through the opening 534h. Accordingly, the water that has entered the inside of the electric wire protection case 500 is quickly discharged to the lower side of the electric wire protection case 500.

  In the electric wire protection case 500, the first bottom wall portion 532 is formed as a part of the lower wall portion 514 protruding from the first side wall portion 511, and the first groove portion 534 is formed of the first bottom wall portion 532. Is formed along the direction protruding from the first side wall portion 11. For this reason, as shown in FIG. 12, the shape of the 1st groove part 534 can be easily shape | molded with the metal molds 600 and 610 etc. which are pulled out along the standing direction of the standing wall part 513. FIG. Accordingly, the first member 510 uses a mold that is pulled out in a direction substantially perpendicular to the surface of the first side wall portion 511, including the formation of the first bottom wall portion 532, the first groove portion 534, and the opening portion 534h. It can be easily manufactured by molding. Therefore, the first member 510 can be easily manufactured without using a special mold slide mechanism to make the drainage structure 530.

  Of course, as for the second member 520, since the protrusion 521a is newly made as a structure for draining water, the gold that is pulled out in a direction substantially perpendicular to the surface of the second side wall 521 is the same as the conventional case. It can be manufactured by molding using a mold.

  Further, since the second side wall portion 521 of the second member 520 is configured to abut against the edge portion on the lower wall portion 514 side of the first member 510, a lower wall is formed on the second side wall portion 521 side. Not necessary. For this reason, the structure of the 2nd member 520 can be simplified.

  Further, since the lower wall portion 514 has a groove side wall portion 534a protruding from the lower wall portion 514 on the side of the first groove portion 534 in the entire protruding direction, the lower wall portion 514 has a groove side wall portion 534a. It becomes difficult to bend in the thickness direction.

  In the above embodiment, the first groove portion 534 has been described as being recessed even at the tip portion 532a of the first bottom wall portion 532, but this is not necessarily required.

  As shown in FIG. 13, the portion including the first bottom wall portion 632 corresponding to the first bottom wall portion 532 in the edge portion on the distal end side of the lower wall portion 614 corresponding to the lower wall portion 514 is linearly continuous. You may be connected. In this case, the first groove portion 634 corresponding to the first groove portion 534 is flush with the upper surface (inner surface) of the lower wall portion 514 at the edge on the distal end side of the lower wall portion 614, and The first side wall portion 511 corresponding to the first side wall portion 511 is inclined downward toward the root and opens through the opening 534h. In this case, since the edge part of the front end side of the lower wall part 614 exhibits a linearly continuous shape, the projecting part as the second side wall part 621 corresponding to the second side wall part 521 of the second member 520 as described above. A shape that does not form 521a, that is, a peripheral edge combined with the first bottom wall portion 632 can be used, and the configuration can be simplified.

  Further, as shown in FIG. 14, the first groove portion 734 corresponding to the first groove portion 534 is opposite in inclination to the first bottom wall portion 732 corresponding to the first bottom wall portion 532, That is, you may form the shape which inclines so that it may go down toward the front-end | tip part side from the base part side of the 1st bottom wall part 532. In this case, it is not necessary to form an opening on the base side of the first bottom wall portion 732. Further, the second side wall portion 721 corresponding to the second side wall portion 521 has a shape that does not form the protrusion 521a as described above, that is, a peripheral edge combined with the first bottom wall portion 732 and a linear edge. What has a part can be used. In this case, the 1st groove part 734 is opened in the outer peripheral side of the 2nd side wall part 721 by the 2nd side wall part 721 side, and internal water is discharged | emitted outside through this opening.

  In this modification, the second side wall portion corresponding to the second side wall portion 721 is formed in a size and shape that covers the opening on the second side wall portion 721 side of the first groove portion 734, and the first An opening may be formed in a portion corresponding to the opening on the second side wall portion 721 side of the groove portion 734.
