  Embodiments of the present invention will be described below with reference to FIGS.

<Configuration of toilet device>
As shown in FIG. 1, the toilet apparatus 21 has a drain pipe 23 extending from a drain port 22 a at the bottom of the bowl 22 toward the rear of the toilet bowl. The hose 25 of the turn trap part 27 is covered and connected. An external water distribution pipe 26 is connected to the case body 24.

  The hose 25 is securely fixed to the drain pipe 23 by using the fastener 35.

  The turn trap portion 27 includes a hose 25 made of an elastic material such as an accordion-like resin or rubber, and a termination member 28 attached to the tip thereof.

  One end of an arm member 29 that transmits the rotation of the rotary shaft portion 30 is attached to the end member 28, and the end portion 31 that is the free end of the turn trap portion 27 in the vertical direction as the arm member 29 is rotated by a motor (not shown). By rotating, it can be discharged after stool.

  As shown in FIG. 2, the fastener 35 is opposed to an arc-shaped holding portion 36 having flange portions 36 a and 36 b at both ends, and an arc-shaped holding portion 37 having flange portions 37 a and 37 b at both ends. It comprises a fixing means 38 for fixing a pair of flange portions (36a and 37a and 36b and 37b).

  The material of the fastener 35 is resin, and the fixing means 38 uses bolts 38a and nuts 38b.

  The flange portions (36a, 36b, 37a, 37b) are provided with insertion holes 39 for bolts 38a, and the opposing flange portions are provided with hooks Q1 and hook locking portions Q2, respectively.

  Here, the inner radius R <b> 1 of the holding portions 36 and 37 is the same length as the outer radius R <b> 2 of the hose 25 in a state of covering the drain pipe 23.

  More preferably, the inner radius R1 of the holding portions 36, 37 is slightly smaller than the outer radius R1 of the hose 25 (for example, minus 0.5 mm), so that the biting when the holding portions 36, 37 are attached to the hose 25 is more preferable. Therefore, the stability of temporary mounting can be further improved.

  The gap Q3 = 1 mm is held between the flange portions (36a and 37a and 36b and 37b) facing each other in a state where the pair of holding portions 36 and 37 are temporarily attached by the hook Q1 and the hook locking portion Q2.

  In addition, a holding portion 40 that temporarily holds the nut 38b is provided on one of the flange portions 37a and 37b with openings on the side surfaces of the flange portions 37a and 37b.

  As shown in FIGS. 3, 4, and 5, the upper holding portion 36 has a cross-sectional groove shape including a bottom surface 41 (width T1 = 13 mm, thickness P = 3 mm) and both side surfaces 42 having a height T2 = 6 mm. A semicircular shape is formed with the bottom surface 41 facing inward.

  The holding portion 36 has a total length S1 = 140 mm, and three sets of reinforcing ribs 43 that are fixed to the bottom surface 41 and both side surfaces 42 are provided in the groove shape of the holding portion 36.

  The hook Q1 is formed to protrude from the bottom surface 41 of the flange portion 36a with a hook allowance P1 = 3 mm, and a reinforcing rib 43 for the hook Q1 is provided on the opposite side of the hook Q1.

  The hook engaging portion Q2 of the flange portion 36b has a thickness P3 = 2 mm of the bottom surface 41 in the area of the hook engaging portion Q2 in order to easily insert the hook Q1, and is located at a position where the length P2 = 5 mm from the front end portion of the flange. A reinforcing rib 43 is provided. For this reason, the hook Q1 having the hooking allowance P1 = 3 mm can be smoothly inserted and hooked from the front end of the flange.

  Next, the structure of the lower holding portion 37 will be described with reference to FIGS. 6 to 9, but the same reference numerals are used for the same configuration as the upper holding portion 36 described in FIGS. 3, 4, and 5. The description is omitted.

  As shown in FIGS. 6, 7, 8 (a), 8 (b), and 9, nuts are provided on both inner side surfaces of the holding portion 40 for the nut 38 b provided on one side surface of the flange portions 37 a and 37 b. A pair of protrusions Y for holding parallel side surfaces (not shown) of 38b are provided.

  The protrusion Y has a semicircular shape with a radius of 0.5 mm. Since both the side surfaces of the nut 38b are in line contact with the protrusion Y, the protrusion Y can be easily inserted and can be stably held so as not to drop off after the insertion. Further, the center of the screw hole of the nut 38b overlaps the center of the insertion hole 39 for the bolt 38a in a state where the nut 38b is inserted in contact with the inner wall of the holding portion 40.

<Operation of toilet device>
As described above, since the inner radius R1 of the holding portions 36 and 37 is the same as the outer radius R2 of the hose 25 in the state of covering the drainage pipe 23, the hook Q1 and the hook Q1 are attached to the hook engaging portion Q2. Since the locking portion Q2 can be stably fixed temporarily, positioning can be performed easily and reliably.

  Since the gap Q3 = 2 mm as a tightening allowance is held between the opposing flange portions (36a and 37a and 36b and 37b), the temporarily fixed holding portions 36 and 37 are finally tightened by bolts 38a and nuts 38b. As a result, it is possible to reliably perform the main fixing at a predetermined position, thereby improving workability.

Since the center of the screw hole of the nut 38b overlaps the center of the insertion hole 39 for the bolt 38a in a state where the nut 38b is inserted in contact with the inner wall of the holding portion 40, the nut 38b Since the bolt 38a can be screwed in without having to hold it by hand, workability is remarkably improved.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is.
