かる。 In these figures, 1 is a cylindrical hollow tube into which a disk-shaped component 2 is attached, and the inner peripheral wall of the hollow tube 1 has a support that receives the lower surface of the peripheral edge of the component 2 along the circumferential direction. A surface 3 is provided. Note that the hollow tube 1 and the component 2 may have any shape such as circular or square. As shown in FIG. 4, reference numeral 5 denotes a plurality of holding plates (six in this example) arranged on the inner peripheral wall of the hollow tube 1 at regular intervals along the circumferential direction. The outer end of the hollow tube 1 is connected to the hollow tube 1 as shown in FIG.
It is inserted into a groove 7 provided in the inner circumferential wall near and above the support surface 3 . Numeral 4 is a bolt for pressing the inner end of the holding plate 5 against the outer peripheral edge of the component 2, and the threaded portion at the tip of the bolt 4 is attached to the outer peripheral edge of the component 2.
It is designed to be screwed into a screw hole provided on the outer peripheral edge of the. 6 is a spacer interposed between each holding plate 5 and the outer peripheral edge of the component 2;
In the illustrated example, it is formed into a ring shape, but
The spacer 6 may be provided only between each presser plate 5 and the component 2, or the spacer 6 may be formed integrally with the component 2 or the presser plate 5.
Part 2 includes a holding plate 5 and a spacer 6 inside the hollow tube 1.
It is attached using bolts 4 as shown in FIG. In this case, when the bolt 4 is tightened, a force W 2 is applied to push the hollow tube 1 up due to the lever action of the holding plate 5 using the spacer 6 as a fulcrum. On the other hand, a force W' 2 that presses the component 2 against the hollow tube 1 is applied to the support surface 3 of the component 2 via the spacer 6.
ボルト４の締結による軸力W1と、支持面３に
かかる軸力W′2との関係は、W1＝W′1、Ｒ＝W2、
R′＝W′2、W2＝W′2W1（l2−l1）＝Rl1の第５図に
示す関係から、
Ｒ＝W′2＝W1（l2−l1）／l1 …(1)
となる。 The relationship between the axial force W 1 due to the fastening of the bolt 4 and the axial force W' 2 applied to the support surface 3 is W 1 = W' 1 , R = W 2 ,
From the relationship shown in Figure 5, R′=W′ 2 , W 2 =W′ 2 W 1 (l 2 −l 1 )=Rl 1 , R=W′ 2 =W 1 (l 2 −l 1 )/ l 1 …(1).
この(1)式から、支持面３にかかる軸力W′2は、
ボルト４の軸力W1と（l2−l2）／l1が大きくなるに
従つて大きくなるから、本取付構造によれば、部
品２には大きな締付力を付与できるわけである。
また、上記第２図に示す取付構造のように、ボル

ルト４のねじ部は部品２にねじ込まれる構造とな
つているので、中空管１の肉厚を肉厚とする要が
ない。 From this equation (1), the axial force W′ 2 applied to the support surface 3 is:
Since the axial forces W 1 and (l 2 −l 2 )/l 1 of the bolt 4 increase as they increase, a large tightening force can be applied to the component 2 according to this mounting structure.
In addition, as in the mounting structure shown in Fig. 2 above, the threaded portion of the bolt 4 is attached to the component 2, instead of screwing the bolt into the threaded hole provided on the support surface of the hollow tube component and tightening the component. Since it has a screwed structure, there is no need to increase the wall thickness of the hollow tube 1.

果を挙げることができる。 Since the structure for mounting parts in the hollow tube of the present invention has the above-mentioned configuration and operation,
According to the present invention, the above-mentioned drawbacks of the conventional method can be solved, sufficient clamping force can be applied to the parts, and there is no need to increase the wall thickness of the hollow tube, making it possible to economically install the parts inside the hollow tube. This has the practical effect of realizing a structure.
