  In the above embodiment, the mounting hole 14 has an oval shape. However, the present invention is not limited to such a configuration. For example, an elliptical shape, a rectangular shape, or the like is long and symmetrical with the long axis as the center line. Any shape can be used.

  Further, although the fixing portion 21 is oval in plan view, it is not limited to such a configuration, and may be a shape corresponding to the mounting hole 14 in a plan view and symmetrical with the long axis as the center line. For example, an oval shape or a rectangular shape corresponding to the mounting hole 14 may be used.

  The engaging portion 25 is configured to be integrally connected to the fixing portion main body 23 via the elastically deformable connecting portion 26, but is not limited to such a configuration, and the fixing portion 21 is inserted into the mounting hole 14. In such a state, any structure that can engage with the peripheral edge of the mounting hole 14 may be used.

  In addition, the engaging portion 25 is configured such that the locking portion 29 provided at the distal end portion can be locked to the peripheral portion of the mounting hole 14, but is not limited to such a configuration, and the fixing portion 21 is mounted. Any structure that can be engaged with the peripheral edge of the mounting hole 14 in a state of being inserted into the hole 14 may be used.

  The flange portion 22 is configured so that the entire one surface of the flange portion 22 contacts the periphery of the mounting hole 14 in the sheet metal 13 in a state where the fixing portion 21 is inserted into the mounting hole 14, but the configuration is limited to such a configuration. Instead, any configuration may be used as long as it does not pass through the mounting hole 14 by contacting two or more places around the mounting hole 14 in the sheet metal 13 with the fixing portion 21 inserted through the mounting hole 14.

  Hereinafter, examples and comparative examples will be described.

  An adjuster drag endurance test was conducted using the adjuster receiving seat having the configuration shown in FIGS. 1 to 5 as an example and using the adjuster receiving seat having the conventional configuration shown in FIG. 6 as a comparative example.

  In the adjuster drag endurance test, the adjuster seats of the examples and comparative examples were attached to the mounting sheet metal (plate thickness 1.2 mm) of the load running tester, and the adjuster was screwed onto the adjuster seat.

  In the embodiment, an adjuster in which a screwing portion is formed of steel (trivalent chromate), a grounding portion is formed of zinc die casting, and an ABS (acrylonitrile-butadiene-styrene) resin is provided on a bottom surface of the grounding portion is used. Was taken as Example 1. Further, Example 2 was made using an adjuster in which the screwing portion was formed of steel (black zinc plating) and the grounding portion was formed of nylon (polyamide). Further, in the comparative example, the same adjuster as in Example 2 was used.

  In addition, the bolt projecting length, which is the length of the threaded portion exposed from the adjuster seat in the adjuster, was 10 mm in Example 1, and 30 mm in Example 2 and Comparative Example.

  Then, with the grounding part of the adjuster grounded on the P tile, which is a hard floor material blended with vinyl chloride resin, a load running tester applies a load of 50 kg, 60 kg or 80 kg to 1.00 km It was checked whether or not the adjuster seat was deformed or disassembled by traveling 100 m on the rotating disk at a speed of / hour. Test conditions and test results are shown in Table 1. The load of 50 kg is a load resistance of a commercially available resin seat.

  As shown in Table 1, neither Example 1 nor Example 2 was deformed or decomposed. Note that when the load was 80 kg or more, the resistance in the testing machine was too strong, so the rotating disk did not rotate.

  On the other hand, in the comparative example, decomposition occurred at a load of 50 kg.

  From the above results, it was confirmed that each example according to the present invention can be easily manufactured and can be easily attached to an attached object, and can also be improved in durability as compared with the conventional configuration.
