  The construction procedure for fixing the above-described heel support 1 and heel 5 to the outer wall of the outer wall 6 will be described. The operator inserts the fixing tool 23 into the communication hole 31 a of the base portion 31, the internal space 21 of the fixing portion 2, and the fixing hole 22, and attaches the fixing tool 23 to the outer wall 6, thereby fixing the heel support 1 to the outer wall 6. . At this time, the heel support 1 is arranged in a line in the vertical direction of the outer wall 6. The operator couples the fitting portion 3 of the heel support 1 with the coupling portion 4 of the heel 5 and fixes the heel 5 to the outer wall 6. At this time, if the outer wall 6 is uneven and uneven, the hook support 1 is displaced in the front-rear direction when the hook support 1 is fixed to the outer wall 6. However, in the heel support 1 and the coupling portion 4 of the present embodiment, a plurality of engaging claws 33 are provided on the support portion 32 and a plurality of engaged claws 43 are provided on the supported portion 42 in the front-rear direction. The operator adjusts the position where the engaging claw 33 and the engaged claw 43 are engaged so that the hook 5 is not bent in the front-rear direction, and engages the engaging claw 33 and the engaged claw 43 with each other. The heel support 1 and the heel 5 are fixed. Next, an elbow (not shown) is disposed between the caller (not shown) and the upper end of the hook 5, and the caller and the hook 5 are connected. Then, a drain pipe cover (not shown) is disposed between the drain tube and the lower end of the trough 5 to connect the drain tube and the trough 5.

  By using the above-described heel support structure, even if the outer wall 6 is uneven and uneven, and the heel 5 is curved and fixed to the outer wall 6 in the front-rear direction, the engagement claw 33 and the engaged claw 33 are engaged. By adjusting the position where the joint claw 43 is engaged, the displacement in the front-rear direction can be absorbed. The engaging claw 33 and the engaged claw 43 are provided with the engaging claw side inclined portion 33 a and the engaged claw side inclined portion 43 a, so that the coupling portion 4 can be easily pushed into the fitting portion 3. Further, the engaging claw 33 and the engaged claw 43 are provided with the engaging claw side vertical portion 33b and the engaged claw side vertical portion 43b, so that it is difficult to pull out the coupling portion 4 from the fitting portion 3. .

  The fitting portion 3 and the coupling portion 4 may have the following configuration. A pair of supported portions 42 protrude in the direction toward the outer wall 6 from both the left and right sides of the base portion 41, and the support portion 32 protrudes in a direction toward the flange 5 from both the left and right sides of the base portion 31. The engaged claw 43 protrudes in the direction in which the left and right supported portion 42 faces, and the engaging claw 33 protrudes in the direction in which the left and right supported portion 42 faces. In this configuration, the fitting portion 3 is fitted into the coupling portion 4. The shapes of the engaging claw side inclined portion 33a, the engaging claw side vertical portion 33b, the engaged claw side inclined portion 43a, and the engaged claw side vertical portion 43b are not changed.

  Next, a second embodiment will be described based on FIG. The second embodiment is a modification of the first embodiment, and the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The support portion 32 includes a pulling portion 34 that protrudes in a direction opposite to the direction in which the support portion 32 in the left-right direction opposes in order to release the engagement between the engagement claw 33 and the engaged claw 43.

  When the coupling portion 4 is pushed too much into the fitting portion 3 or when the coupling portion 4 is desired to be pulled out from the fitting portion 3, the coupling portion 4 is pulled backward. Here, if pulled in the rear direction as it is, since the engaged claw 43 is engaged with the engaging claw 33, it is difficult to pull out, and in the worst case, the engaging claw 33 and the engaged claw 43 are damaged. There is a risk of it. Therefore, the support part 32 is pulled in the direction opposite to the direction in which the support part 32 in the left-right direction opposes. And the coupling | bond part 4 was pulled out from the fitting part 3 by expanding the left-right support part 32 in the direction opposite to the direction where the support part 32 opposes. However, when the support portion 32 is provided, the left and right support portions 32 have upper and lower end portions, but the left and right support portions 32 have a narrow width in the left-right direction, which is difficult to hold. Therefore, in this embodiment, the tension part 34 is provided over the entire length of the support part 32 in the vertical direction. In addition, the tension | pulling part 34 may be provided in a part of the up-down direction of the support part 32, and does not need to be provided over the full length of the up-down direction of the support part 32. FIG.

  Accordingly, the pulling portion 34 is picked with a finger, and the pulling portion 34 is pulled in the direction opposite to the direction in which the left and right support portions 32 face each other, whereby the support portion 32 is made in the direction opposite to the direction in which the support portions 32 face each other. Can be easily expanded.

  In addition, when it is set as the structure by which the above-mentioned fitting part 3 is engage | inserted inside the coupling | bond part 4, the tension | pulling part 34 is made to project in the direction opposite to the direction where the supported part 42 of the left-right direction opposes.
