Bearing components 27, is supported by the surrounding with supporting member 21 (upper split component 22 and lower split component 23) clamping elastic component 272.

As shown in Figure 6, the edge at the axial both ends of elastic component 272 is formed prominent to radial direction a pair flange portion 273, this flange portion 273 contacts with supporting member 21 axial end portion, thus limiting bearing components 27 (jackshaft s3) relative skew in the axial direction. It addition, at the outer peripheral face of elastic component 272, the lobe 274 of prominent hole portion 225 tabling being formed and formed on upper split component 22. This lobe 274 is entrenched in split component 22 hole portion 225, so that bearing components 27 and supporting member 21 (upper split component 22) are positioned, stop the bearing components 27 (intermediate support A) rotation relative to supporting member 21 simultaneously.

Hereinafter, the lower split component 23 of composition supporting member 21 bottom is illustrated.

As shown in Figure 4, lower split component 23 has: as the fixed support 24 of lower half fixed part, this lower half fixed part welding in spring housing 19 at overall width direction Y towards on the sidewall of inner side; And lower half fastening part 25, it screws tight the bottom at fixed support 24. Lower split component 23 is combined by fixed support 24 and lower half fastening part 25 and is constituted, and is therefore formed as intermediate support A (bearing components 27) bottom of collateral support jackshaft s3 from below.

Fixed support 24 is formed as the bending rack vertically bending and extending. Fixed support 24 has many places to be fixed on the sidewall of spring housing 19 by weld portion w (with reference to Fig. 5 (a), Fig. 5 (b)) welding.

As shown in Fig. 4, Fig. 5, Fig. 6, the above-below direction of fixed support 24 is substantially centrally formed the outside stress surface f1 tilted obliquely upward on the Y of overall width direction towards outside. Outside stress surface f1 is formed as making outer lower portion abut against with it on the overall width direction Y of bearing components 27 (intermediate support A). Above the stress surface f1 of outside, vertically having extended to form holding section, fixing side 241, this holding section, fixing side 241 has the opening b1 making split component 22 engage. On the other hand, in the lower section of outside stress surface f1, it is formed with the fastening face f2 with screw, and welding has fastening nut nt on the dorsal part wall relative with the fastening face f2 of fixed support 24.

As shown in Figure 4, lower half fastening part 25 is extended on above-below direction, makes bottom be fixed on and extends to the direction (inner side of overall width direction Y) away from fixed support 24 on fixed support 24. Lower half fastening part 25, has the fastening end 251 in its bottom with the fastening face f2 weight merga pass bolt V fastening of fixed support 24. Additionally, lower half fastening part 25 has the bending principal part 252 of strip, this bending principal part 252 is with fastening end 251 for cardinal extremity, and from this fastening end 251 to overall width direction, oblique upper extends to form. Bending principal part 252, constitutes the inner side stress surface f3 having lower inside to abut against at bearing components 27 (intermediate support A) on the Y of overall width direction. As shown in Figure 6, in the upper end of lower half fastening part 25, namely above bending principal part 252, being formed with fastening holding section, side 253, this holding section, fastening side 253 has card and closes the opening b1 of split component 22. In such lower half fastening part 25, along the two ends of bearing of trend, in other words, along the edge of the axially rear ends of the jackshaft s3 constituting intermediate support A, it is bent to form end flange 254, is strengthened the rigidity of bending principal part 252 by end flange 254.

By the fixed support 24 combining the lower half fastening part 25 so strengthening rigidity with pass through weld portion w welding in spring housing 19, constitute and firmly descend split component 23. And, on lower split component 23, between fastening half portion 25 and fixed support 24, it is formed with spill forced section 231 (with reference to Fig. 5 (a)) opened above. As shown in Fig. 4 (a), Fig. 4 (b), jackshaft s3, when the bearing components 27 of intermediate support A is embedded in the forced section 231 of lower split component 23, fixes from below and is supported. It addition, in this case, owing to the latter half of the bearing components 27 of intermediate support A is surrounded by lower split component 23, therefore the movement on the Y of overall width direction is limited. And, the forced section 231 of lower split component 23 is in the both sides of overall width direction Y, relative configuration has the holding section, fixing side 241 with opening b1 and the holding section, fastening side 253 with opening b2, and engages split component 22 on these holding sections, fixing side 241 and fastening holding section, side 253.

Hereinafter, the upper split component 22 constituting supporting member 21 top is illustrated.

Upper split component 22 is formed as peripheral part on the upside of the bearing components 27 with intermediate support A and abuts against, and matches with lower split component 23 and clamp bearing components 27.

Upper split component 22, including the banding principal part 221 of arc-shaped, this banding principal part 221, for making it be wrapped in the upside outer peripheral face of the elastic component of bearing components 27 272 and the shape of upside peripheral part according to elastic component 272, is bent to semicircular arc; And claw 223,224, it is formed at the length direction two ends of banding major part 221. It addition, the pars intermedia of the length direction at banding principal part 221, being formed with the hole portion 225 chimeric with lobe 274, this lobe 274 is formed from the elastic component 272 of bearing components 27 is prominent.

Each claw 223,224 is formed as hook-shaped, and a claw 223 is fastened on the opening b1 of holding section, fixing side 241 separatably, and other claws 224 are sticked in the opening b2 of fastening holding section, side 253. That is, upper split component 22 is extended on the Y of overall width direction, and the claw 223,224 at both ends engages with fastening half portion 25 of inner side on the superolateral fixed support 24 of overall width direction Y and overall width direction Y respectively. Upper split component 22 is configured to be wrapped in the upside peripheral part of bearing components 27, and the claw 223,224 at two ends engages with lower split component 22, thus reliably clamping the bearing components 27 of intermediate support A from above and fixing.

It is different that claw 223 is arranged to its deformation intensity with claw 224. Specifically, the width d1 (with reference to Fig. 5 (c)) being fastened on the claw 223 of fixed support 24 side is formed as narrower than the width d2 of the claw 224 being fastened on lower half fixed part 25 side (with reference to Fig. 5 (b)), and the deformation intensity of claw 223 is set to less than claw 224.

Accordingly, when being subject to specifying above load from jackshaft s3, the claw 223 of fixed support 24 side deforms and departs from from opening b1. That is, the structure of upper split component 22 is, when making jackshaft s3 push up upward due to the collision etc. of vehicle 2, the end outside overall width direction departs from from lower partition member 23.

Hereinafter, the action of the steering spindle supporting construction 1 of Fig. 1 is illustrated together with the action of transfer 4.

Before this action is described, first clamping bearing components 27 (intermediate supports portion A) to lower split component 23 and upper split component 22, on the sidewall of spring housing 19, the step of pivot support jackshaft s3 is illustrated.

In this case, first, as in figure 6 with shown in symbol g1, in mounting, the banding principal part 221 of split component 22 makes it cover the upside outer peripheral face of the elastic component 272 of bearing components 27 (intermediate supports portion A). Now, banding principal part 221 is sandwiched between the flange portion 273 at the axial both ends of elastic component 272, chimeric with the lobe 274 of the elastic component 272 of bearing components 27 with hole when portion 225. Accordingly, upper split component 22 is positioned relative to bearing components 27, and is in empty fixing state. Secondly, as in figure 6 with shown in symbol g2, (outside overall width direction) claw 223 for upper split component 22 is fastened on the opening b1 of the fixed support 24 being fixed on spring housing 19 sidewall, as in figure 6 with shown in symbol g3, the opening b2 making lower half fastening part 25 is sticked in other (inside overall width direction) claws of split component 22, and lower half fastening part 25 remains hang (double dot dash line with reference to Fig. 4 (a)).

Next, when the outside stress surface f1 making bearing components 27 be connected to fixed support 24, the fastening end 251 making lower half fastening part 25 overlaps with the fixed support 24 fastening face f2 inside overall width direction, make bolt V through fastening end 251, this bolt V is fastened on nut nt (with reference to Fig. 4 (b)). Accordingly, lower half fastening part 25 and fixed support 24 are integrated, so jackshaft s3 is when above split component 22 and lower split component 23 clamp bearing components 27 (middle support member A) upper and lower, are supported on the sidewall of spring housing 19.

Now, by suitably setting the magnitude of interference between fastening end 251 and fastening face f2, it is possible under adjusting, split component 23 and upper split component 22 are applied to the chucking power of bearing components 27.

Assume that the vehicle 2 with so transfer 4 of assembling normally travels.

In this case, if by driver's slewing maneuver steering wheel 8, then steering force is delivered to tooth sector 9 by steering spindle row Sa, and left and right front-wheel 3 can be switched manipulation into required direction by the steering force of the left and right directions by being changed by tooth sector 9.

On the other hand, when vehicle 2 collides, once the front portion of curb girder 13 and front end cross beam 131 retreat displacement, correspondingly, the mistake load of direction of retreat can be passed on tooth sector 9 and the steering spindle row Sa that is connected with tooth sector 9 side. Now, because being subject to the mistake load of the vehicle front from vehicle 2, top pushing force is applied in the upper split component 22 of supporting member 21 from jackshaft s3.

Owing to the close lower split component 23 of split component 22 of card is fixed in spring housing 19, therefore upper split component 22 is subject to top pushing force, and at both ends, overall width direction, tensile force can be applied to the claw 223 and 224 being fastened on lower split component 23. If acting on the load of split component 22 beyond regulation, then deformation intensity is set as that relatively low claw 223 deforms, and departs from (with reference to Fig. 4 (b)) from the opening b1 of fixed support 24.

If the disengaging of claw 223 makes split component 22, the end outside overall width direction departs from from fixed support 24, then go up split component 22 and shifted upward by jackshaft s3 (bearing components 27) extruding. Now, claw 224 inside overall width direction engages with lower split component 23 (lower half fastening part 25), so claw 224 becomes fulcrum when engaging with peristome b2, to turn inside overall width direction centered by the upper split component 22 end (claw 224) inside overall width direction, so that departing from from bracing frame 24.

So, upper split component 22 is the structure with claw 224 for fulcrum turn, so when jackshaft s3 departs from from supporting member 21, upper split component 22 is always positioned at (inner side of engine room 7) inside the overall width direction of intermediate support A (bearing components 27). Accordingly, it is possible to suppress jackshaft s3 to displacement inside overall width direction by upper split component 22. There is the wall of spring housing 19 outside overall width direction, so jackshaft s3, its moving direction is restricted to top due to the wall of upper split component 22 and spring housing 19. That is, the off-direction of jackshaft s3, is controlled in upwardly direction by upper split component 22.

Meanwhile, the intermediate support A (bearing components 27) of jackshaft s3 departs from upward from the forced section 231 of lower split component 23.

Once intermediate support A from supporting member 21 fixing disengaging, as shown in Figure 7, be positioned at the universal joint j2 of steering spindle row Sa pars intermedia, from by the displacement of the steady statue shown in symbol P1 to shift position when inputting by the symbol P2 mistake load represented above it, increase flexibility. According to displacement bent above, it is possible to absorb retrogressing displacement anterior for steering spindle row Sa, move it is possible to stop or at least can reduce the retrogressing at steering spindle row Sa rear portion. Therefore, it is possible to prevent from or suppress the steering wheel 8 of steering spindle row Sa rear end to push up rearward shifting, it can be ensured that and the front space between driver.

As it has been described above, the steering spindle supporting construction 1 according to present embodiment, upper split component 22 is moved while turn with the end inside the Y of overall width direction for fulcrum to overall width direction Y. Accordingly, it is possible to allow that the intermediate support A's that supports steering spindle and jackshaft s3 is displaced over, it is possible to reliably make jackshaft s3 depart from, it is possible to the rear end side top of suppression jackshaft s3 shifts to side, car room 5.

It addition, when jackshaft s3 departs from from supporting member 21, upper split component 22 is always positioned at the intermediate support A inner side at overall width direction Y, it is possible to suppress jackshaft s3 to the movement inside the Y of overall width direction. Therefore, when jackshaft s3 and supporting member 21 depart from, it is possible to suppress to interfere peripheral components etc. to overall width direction Y medial displacement. So, by controlling the intermediate support A disengaging upward of jackshaft s3, jackshaft s3 can be made during collision reliably to depart from, and off-direction can be controlled and suppress the interference with peripheral components.

It addition, lower split component 23 has forced section 231, go up split component 22 simultaneously and there is banding principal part 221, it is possible to be reliably fixed from the intermediate support A clamping jackshaft s3 up and down.

Additionally, when load is transfused to from jackshaft s3, owing to load can be reliably transmitted to upper split component 22, it is possible to reliably carry out the disengaging from supporting member 21. Especially, because the lower split component 23 higher in the rigidity being fixed on body side spring housing 19 is provided with spill forced section 231, so when jackshaft s3 departs from, being suppressed to the movement on the Y of overall width direction by lower split component 23, the disengaging of upward direction becomes reliable.

In addition, chimeric with the hole portion 225 of upper split component 22 by the lobe 274 that makes bearing components 27, during assembling can locating shaft bearing member 27 and upper split component 22, simultaneously can upper split component 22 void be fixed on bearing components 27, therefore improve assembly working efficiency. Additionally, when fixing bearing components 27 with supporting member 21, it is possible to stop rotating against of bearing components 27 and supporting member 21.

Additionally, constitute upper engaged between split component 22 and lower half fixed part 24 and the lower half fastening part 25 of lower split component 23, therefore make to become easy from the assembly working clamping intermediate support A up and down.

Additionally, be installed with lower split component 23 in spring housing 19, therefore on making, split component 22 bears when coming from extruding force above intermediate support A, and the movement that claw 223 deforms and departs from from holding section 241, fixing side carries out reliably.

Above, better embodiment of the present utility model is illustrated, but this utility model is not limited to above-mentioned specific embodiment, as long as not being particularly limited in the above description, all various deformation and change can be carried out in this utility model teachings described in right.

Such as, in the steering spindle supporting construction 1 shown in Fig. 1, describe and the intermediate support A of steering spindle row Sa is located on jackshaft s3, but, intermediate support A can also be located on outrigger shaft s2, when using other steering spindles row, it is also possible to be provided on the axle of pars intermedia of other steering spindles row. Even if adopting other structure like this, it is also possible to obtain the action effect roughly the same with the steering spindle supporting construction 1 shown in Fig. 1.

Additionally, in steering spindle supporting construction shown in Fig. 11, the lower split component 23 of the supporting member 21 of the intermediate support A of clamping steering spindle is fixed in spring housing 19.
