  FIG. 15 shows a pin elastic retaining means 60 provided with a taper so that the pin insertion hole 44 of the level adjuster 10 according to the second embodiment becomes narrower in the depth direction symmetrically from both sides. It shows that it is the same structure as the structure of FIG. 8 of the level adjuster 10 by 1st Embodiment.

  The level adjuster 10 according to the second embodiment has the same structure as that of the level adjuster 10 according to the first embodiment except for the structure described above, and the functions and effects thereof are the levels according to the first embodiment. Since the function and effect of the adjuster are the same, the description thereof is omitted.

  A level adjuster 10 according to a third embodiment of the present invention is shown in FIGS. 16 to 22. In the level adjuster 10 according to this embodiment, a pedestal 20 includes a flat base 20B and this base. The pedestal main body 20M is formed in a substantially rectangular shape so as to extend from the vicinity of the center of 20B to the vicinity of its peripheral surface, and the screw 30 is a recess provided in the pedestal main body 20M at a position corresponding to the vicinity of the center of the base 20B. As in the first and second embodiments, the two pin portions 42A and 42B of the retaining pin 42 are inserted into the pin insertion hole 44 of the pedestal main body 20M to prevent the collar 30F of the screw 30 from coming off. The base 20 is assembled.

  In the third embodiment, the positioning means 50 is provided in the inner part of the pin insertion hole 44 of the pedestal main body 20M without two bulging portions in the two pin portions 42A and 42B of the retaining pin 42. It consists of the wall surface which the front-end surface of pin part 42A, 42B latches (refer FIG. 21).

  As described above, when the positioning means 50 of the third embodiment is formed of the inner wall of the pin insertion hole 44, as shown in FIG. 21, the pin insertion hole 44 cannot be bidirectional. Since the front end portions of the pin portions 42A and 42B of the retaining pin 42 abut against the inner wall surface of the pin insertion hole 44, the pin portions 42A and 42B are swollen as in the first and second embodiments. It can be seen that the parts 50A42A and 50B are not required.

  Further, in the illustrated third embodiment, since the pedestal main body 20M extends to the peripheral surface of the base 20B, the grip portion 42G of the retaining pin 42 protrudes from the base 20B (FIG. 17, If the pedestal main body 20M does not extend to the peripheral surface of the base 20B but ends in front of it, the grip portion 42G does not protrude from the pedestal 20. In the latter case, the grip portion 42G is positioned on the upper surface of the base 20B, so that it is difficult to place a finger on the grip portion 42G. To avoid this, as shown in FIG. It is possible to change the direction from the pin portions 42A and 42B in the direction perpendicular to make it easy to put a finger.

  The level adjuster 10 according to the third embodiment has the same structure as the level adjuster 10 according to the first and second embodiments except for the structure described above, and the function and effect thereof are the first and second. Since the function and effect of the level adjuster according to the embodiment are the same, the description thereof is omitted.

  In any of the first to third embodiments of the present invention, there is a gap G between the flange 30F of the screw 30 and the peripheral wall of the recess 22 so that the screw 30 can swing in the recess 22. (See FIGS. 5, 18, and 20). This swinging is useful to be able to follow when the floor on which the pedestal 20 is placed is inclined or the floor is uneven.

  Similarly, in any of the first to third embodiments, it is preferable that the pin portions 42A and 42B of the retaining pin 42 and the flange 30F of the screw 30 have a slight gap D (FIG. 5). FIG. 13 and FIG. When the floor is tilted with respect to the horizontal plane due to the occurrence of an earthquake, the pedestal 20 is similarly tilted, but one of the pin portions 42A and 42B of the retaining pin 42 inserted into the pedestal 20 is Even if it raises with respect to the other, it does not push up the flange 30F of the screw 30, and it is possible to prevent the inclination of the floor from being transmitted to the installation object. This is useful for effectively preventing transmission of vibrations to the installation object, in combination with the base 20 having the mat-like earthquake-resistant member 72 of the earthquake-resistant means 70.

  Similarly, this is common to the first to third embodiments, but in the illustrated example, the pin portions 42A and 42B of the retaining pin 42 are provided with springiness by spreading toward the end. Therefore, the outer peripheral surface on the outer side of the portion of the pin portions 42A and 42B that overlaps the recess is the inner peripheral surface on the outer side of the two pin insertion holes 44 (for example, the pin insertion hole 44 on the right side in FIG. 6). The inner peripheral surface on the right side, the inner peripheral surface on the left side of the left pin insertion hole 44, and the same inner peripheral surface in FIGS. 14 and 21) are in surface contact with each other and overlap the recesses of the pin portions 42A and 42B. The pin portions 42 </ b> A and 42 </ b> B of the retaining pin 42 are more reliably prevented from coming off without spreading out.

  The level adjuster of the present invention is not limited to the structure according to the first to third embodiments described above. For example, the positioning means 50 is provided between the pin portions 42A and 42B of the retaining pin 42 and the pedestal. It may be formed between the grip portion 42G of the retaining pin 42 and the base. The pin elastic retaining means 60 has an elastic layer in the pin portions 42A and 42B and can easily insert and remove these pin portions 42A and 42B by hand. The portions 42 </ b> A and 42 </ b> B may be prevented from coming out of the pin insertion hole 44 without being unintentionally pulled out.

  As shown in FIG. 23D, the grip portion 42G of the retaining pin 42 is expanded to have a width larger than the interval between the two pin portions 42A and 42B, and the retaining pin 42 is further inserted and removed. It can be done easily.

  Since the level adjuster of the present invention can prevent the screw from coming off by inserting the retaining pin, the screw can be quickly attached and detached, and the two pin portions of the retaining pin are pin insertion holes of the base. Since the screw is frictionally engaged with the inner surface, the screw can be stably retained on the pedestal and has industrial applicability.
