Further, the distance between the threaded portion 3b of the height adjusting bolt 3 and the fixing bolt 7 is shortened, and further, both ends of the adjuster foot body can be fixed by the fixing bolt 7, so that it can be applied in all three-dimensional directions of the space. On the other hand, the strength is higher than in the conventional case, and the housing 10 is securely fixed.

Embodiment 2 FIG. 3 is a vertical cross-sectional view of a second embodiment of the present invention, and FIG. 4 is a BB arrow view thereof. Reference numeral 12 denotes a base placed on the floor 6, which is made of an insulating material such as hard rubber or polyacetal resin and having a strength capable of withstanding bolt fastening. 3
Is a knob 3a (hereinafter referred to as the head) at the bottom of the screw 3b.
With the height adjustment bolt that is fixed, this height adjustment bolt 3
A metal disk-shaped embedded leg portion 13 is fixed to the head portion 3a, and the lower portion of the head portion 3a is inserted into the base 12 and integrally molded. The embedded leg portion 13 may be fixed to the head portion 3a of the height adjusting bolt 3 by welding or the like, or the head portion 3a and the embedded leg portion 13 may be integrally formed by welding and the like. It may be fixed to the end of the threaded portion 3b of the height adjusting bolt 3 by welding or the like. The base 12 and the height adjusting bolt 3 form an adjuster foot body for height adjustment.

4a and 13a are a base 12 and an embedded leg 1.
A plurality of (6 in this embodiment) concentric circles centering on the height adjusting bolt 3 are provided at the screw insertion holes provided in the No. 3. The inner peripheral portion and the peripheral portion of the screw insertion hole 13a of the embedded leg portion 13 are covered with the same material as the insulating material forming the base 12 or another insulating material in order to bring it into an insulating state. The metal part is not exposed. Therefore, the diameter of the bolt insertion hole 4a is smaller than the diameter of the bolt insertion hole 13a of the embedded leg portion 13 by the thickness of the insulating member.

Numeral 5 is a screw hole provided in the floor 6 corresponding to the bolt insertion holes 4a and 13a, and the fixing bolt 7 is fixed to the bolt insertion holes 4a and 13 through spring washers and washers.
The adjuster foot main body is fixed to the floor 6 by inserting it through a and screwing it into the screw hole 5. Reference numeral 10 denotes a housing of an electronic device or the like, and 11 denotes a housing nut fixed on the hole 10a provided in the housing 10 by welding so that the hole 10a and the screw portion overlap with each other. Then, the threaded portion 3b of the height adjusting bolt 3 is screwed into the nut 11 through the hole 10a.

In this embodiment constructed as described above, when the head portion 3a of the height adjusting bolt 3 of the adjuster foot body is rotated, the screw portion 3b is rotated together with the base 12 on the floor. Therefore, the threaded portion 3b of the height adjusting bolt 3
The nut 11 that is screwed in the vertical direction moves up and down along the threaded portion 3b, and the height of the casing 10 integrated with the nut 11 is adjusted.

Next, the screw insertion hole 4a of the adjuster foot body located closest to the screw hole 5 provided on the floor 6 is aligned with the screw hole 5, and the fixing bolt 7 is fixed to the spring washer.
The housing 10 is screwed into the screw hole 5 of the floor 6 from the bolt insertion hole 4a of the adjuster foot body through the washer, and the fixing bolt 7 is tightened to fix the housing 10 to the floor 6 through the adjuster foot body.
Fixed to.

Therefore, according to the present embodiment, the fixing metal fittings, the bolts for fixing one end of the fixing metal fittings to the floor, the spring washers, and the tightening nuts screwed to the height adjusting bolts, which have been indispensable in the past, are used. Since the above can be omitted, not only the mounting becomes easy, but also the cost can be reduced. Further, the distance between the threaded portion 3b of the height adjusting bolt 3 and the fixing bolt 7 is shortened, and further, both ends of the adjuster foot body can be fixed by the fixing bolt 7, so that it can be applied in all three-dimensional directions of the space. On the other hand, the strength is higher than in the conventional case, and the housing 10 is securely fixed. Moreover, since the fixing bolt 7 is insulated from the threaded portion 3b, the head 3a, and the embedded leg portion 13 of the height adjusting bolt 3 that is in conduction with the housing 10, the fixing bolt 7 is insulated from the fixing bolt 7. Can be secured.
