2. FIELD OF THE INVENTION AND RELATED ART STATEMENT
The present invention relates to a mounting structure for mounting the lower arm bracket of the suspension to a vehicle body in the suspension to be used in the motor vehicles etc.
There are known prior mounting structures of the type wherein a sleeve nut c is secured by means of welding and the like at its opposite ends to a lower side member a and a gusset plate b, as shown in Fig. 3, and a bolt d is threadably inserted into the sleeve-nut c to fix the lower arm bracket e in position between the bolt d and the lower side member a.
Also known is of such type as wherein a sleeve f is interposed between the lower side member a and a gusset plate b as shown in Fig. 4, and a nut g is secured in place on anupper surface of the gusset plate b by means of welding etc., and while a bolt d is threadably inserted into a lower side member a through a lower arm bracket e and a sleeve f which abut with the lower side member a, and the tip end of the bolt d is threadably inserted into the nut g fcr securement.
Meanwhile, a clearance h is created at the threaded portion between a bolt d and a sleeve nut c (or a nut g) as shown in Eig. 5. Therefore~ there was a problem that 2029~2fi when an external force larger than a frictional force to be created at the threaded portion is imposed at the lower arm bracket e, the bolt d is caused to move by a distance h equal with this clearance, and thereby altering the alignment of the suspension.

5. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
One embodiment of the present invention will be described hereinbelow, with reference to accompanying drawings.
In Fig.1, there are illustrated a lower side member 1, a gusset plate 2, and a side member barrier 3. The lower side member 1 and the gusset plate 2 are connected each other through welding at their opposide ends respectively, as shown. A hole 4a in the sleeve 4 is aligned with a hole 1a defined in the lower side member 1, or the hole 1a is made slightly larger in diameter A
tapered portion 4b is formed at the central circumferential wall of the sleeve 4's hole 4a. A female threaded hole 4c is formed at a upper position above the tapered portion 4b. A bolt 5 is provided, having a stem portion 5a and a male threaded portion 5c with a tapered portion 5b therebetween.
In Fig. 2, a lower arm 6 is illustrated as installed in a front suspension, having a mounting hole 7a defined in the bracket 7 of the lower arm 6. The stem portion 5a of the bolt 5 is inserted into the mounting hole 7a, and the lower arm bracket 7 is fixed in position on the lower 2029~26 side member 1 by threadably inserting the make threaded portion 5c into the female threaded portion 4c in the sleeve 4. Meanwhile, the hole 4a in the sleeve and the mounting hole 7a in the lower arm bracket 7 are placed in an engaging relationship with the stem portion 5a of the bolt 5 by making their diameters substantially equal. A
clearance to be created between their engaging faces is made smaller in diameter than that to be created when the threaded portion is inserted (see Fig. 5, h).
This embodiment is constituted as above-described, and therefore the bolt 5 is restricted from moving further as the stem 5a of the bolt 5 is in abutment against the inner surface of the hole 4a of ther sleeve 4, even when external forces larger than a frictional force to be created at the threaded portion is imposed on the lower arm bracket 7.
In this embodiment, a sleeve 4 is interposed between the lower side member 1 and the gusset plate 2, but it may also be possible for the hole 4a and the female threaded hole 4c to be formed dlrectly in the lower side member 1, if the vehicle body member comprises a thick portion which is substantially close to the height dimension of the Because the hole in the vehicle body is formed in an engaing relationship with the stem portion of the bolt by making their diameters substantially equal, the suspension may not alter its alignment as the movement of the bolt is 2029~26 restricted by the vehicle member even when external forces larger than a frictional force to be created at the threaded portion is imposed on the lower arm bracket.
