  The front member 5 is detachably attached to the front side of the fixture main body 4. The front member 5 includes a vertical surface portion 54, an extending piece 55, a second protrusion 53, and a lower extending piece 57.

  The vertical surface portion 54 has a length in the vertical direction and a width in the horizontal direction. The vertical surface portion 54 is formed in the same size as the main body portion 41 in front view (that is, the outer edge of the vertical surface portion 54 and the outer edge of the main body portion 41 substantially coincide with each other in plan view). The extending piece 55 extends rearward from both ends in the width direction of the vertical surface portion 54. The extending piece 55 is overlaid on the outer surface of the side surface portion 45 of the main body portion 41. The second ridge 53 extends rearward from the upper end of the vertical surface portion 54. The projecting tip of the second protrusion 53 is formed in an arc shape in plan view.

  The extension piece 55 is provided with a fixing tool insertion hole 56. Further, a screw hole 49 is provided in the side surface 45 of the fixture main body 4 at a location corresponding to the fixing tool insertion hole 56 of the extension piece 55. The fixing tool main body 4 and the front member 5 are mutually connected by the fixing piece 8 being inserted into the fixing tool insertion hole 56 and screwed into the screw hole 49 in a state where the extending piece 55 and the side surface portion 45 are overlapped. Fixed.

  The lower extension piece 57 extends rearward from the lower end portion of the vertical surface portion 54. The lower extension piece 57 and the vertical surface portion 54 are orthogonal to each other. When the front member 5 is attached to the fixture main body 4, the lower extension piece 57 comes into contact with the upper surface of the bottom surface portion 44 of the main body portion 41.

  Further, the elastic material 7 is adhered to the rear surface of the vertical surface portion 54. As shown in FIG. 8, the elastic material 7 is disposed so as to contact the upper edge portion of the recess 22 of the rainwater tank 1.

  The fixing structure of the rainwater tank 1 of this embodiment is attached and constructed as follows.

  The installer places and fixes the fixture main body 4 at a predetermined position on the installation surface 6 (see FIG. 8A). Next, the installer slides the rainwater tank 1 from the front of the fixture body 4 toward the fixture body 4. Thereby, the 1st horizontal groove part 281 opened toward the back of the rainwater tank 1 is passed through the 1st protrusion 43 of the fixing tool main body 4 from the front (refer FIG.8 (b)).

  Next, the installer attaches the front member 5 to the fixture main body 44. The installer attaches the front member 5 to the fixture main body 4 so that the second protrusion 53 of the front member 5 is fitted into the second lateral groove 282 of the rainwater tank 1. As a result, the second protrusion 53 of the front member 5 is fitted into the second lateral groove 282 of the rainwater tank 1, and the first protrusion 43 of the fixture main body 4 is the first protrusion 43 of the rainwater tank 1. It fits into the lateral groove 281 (see FIG. 8C).

  According to the fixing structure of the rainwater tank 1 of the present embodiment, as in the first embodiment, the installed rainwater tank 1 can be prevented from floating from the installation surface 6, and the rainwater tank 1 can be firmly fixed. Moreover, since the builder can slide the rainwater tank 1 on the installation surface 6 and move it to the fixture body 4 fixed to the installation surface 6 in advance, the rainwater tank 1 can be installed without lifting. Can be constructed. As a result, according to the fixing structure of the rainwater tank 1 of this embodiment, the workability of installing the rainwater tank 1 can be improved.

  Further, the fixing member 3 of the present embodiment is provided with the elastic material 7 on the rear surface of the front member 5, the front surface of the standing piece 422, and the top surface portion 47 of the main body portion 41. That is, since the elastic material 7 is provided at the place where the fixture 3 and the rainwater tank 1 are in contact with each other, the rattling of the rainwater tank 1 can be suppressed while the rainwater tank 1 is fixed to the fixture 3. Can do. As shown in FIG. 8, the elastic material 7 provided on the top surface portion 47 does not contact the rainwater tank 1 when installed, but contacts the rainwater tank 1 when rainwater is stored in the rainwater tank 1. It is supposed to be.

  Moreover, the protrusion front-end | tip of the 1st protrusion part 43 and the 2nd protrusion part 53 of this embodiment is formed in circular arc shape by planar view, and the 1st horizontal groove part 281 of the rainwater tank 1 or the 2nd horizontal groove The shape is along the portion 282. For this reason, the 1st protrusion part 43 and the 2nd protrusion part 53 contact | abut to the 1st horizontal groove part 281 or the 2nd horizontal groove part 282 of the rainwater tank 1 linearly. Thereby, according to the fixing structure of the rainwater tank 1 of this embodiment, the rattling of the rainwater tank 1 in the installed state is further suppressed.
