It can be adjusted.

  In this embodiment, the frame 11 on the chassis side is constituted by the left and right rail-like parts 11A each having a substantially U-shaped cross section extending in the vehicle front-rear direction, and the plate-like portions of the rail-like parts 11A. 11 b is integrally formed on each upper portion of the frame 11. Each beam 21, panel 22 and each pair of mounting plates 23 of the mounting component 20 constitute a panel-like fixed portion 24 of the mounting component 20 provided between the left and right rail-shaped components 11A as a whole. The clamp brackets 25 are interposed between the left and right rail-shaped components 11A and both ends of the panel-shaped fixed portion 24, respectively.

  Further, in the tractor 1 of the present embodiment, the fixed portion 24 of the mounted component 20 is disposed on the vehicle front side with respect to the semi-trailer towing coupler 12 supported by the left and right rail-shaped components 11A. A panel 22 having a main part of a panel 22 provided between the left and right rail-like parts 11A is configured, and the panel-like fixed part 24 allows the routing parts 2 and the trailer 2 (not shown) on the frame 11 side. The connecting pipes 5 connected to the (semi-trailer) are separated in a vertically separated state.

  Next, an assembling operation of the mounted component 20 on the frame 11 will be described.

  As shown in FIG. 4, prior to the assembly work of the clamp bracket 25, the other screw coupling portion 28b is screw-coupled to the one screw coupling portion 28a in the non-tightened position.

  On the other hand, as shown in FIGS. 1 to 3, a pair of mounting plates 23 positioned on both ends of the panel-like fixed portion 24 of the mounting component 20 are arranged on the left and right rail-like components 11 </ b> A of the frame 11. The pair of mounting plates 23 of the panel-like fixed portion 24 of the mounted component 20 are positioned on the frame 11 by temporarily inserting a guide pin for positioning into the guide hole 23h or the like.

  Next, with respect to the plate-like portion 11b of the frame 11 protruding to the right side in FIG. 3, the clamp type bracket 25 is moved from the right side to the left side in the same figure in the direction of the thick arrow in FIG. The vertical plate portion 26 a of the bracket 25 is brought into contact with the side plate portion 23 a of the mounting plate 23. Here, the coupling nut 26e of the mounting side coupling portion 26 may be temporarily tightened.

  When the vertical plate portion 26a of the clamp-type bracket 25 is brought into contact with the side plate portion 23a of the mounting plate 23, the fastening portion 27d previously held movably within a predetermined gap range by the vise clamp portion 27 of the clamp-type bracket 25. One screw coupling portion 28a is close to the inner end edge 11e of the plate-like portion 11b of the frame 11, and takes a posture close to the above-described final fastening posture while absorbing variations in the combination dimensions of the components.

  Next, in a state where one screw coupling portion of each fastening portion 27d is close to the inner end edge 11e of the plate-like portion 11b of the frame 11, the other screw coupling portion 28b that is screw-coupled to one screw coupling portion 28a is tightened. The mounting plate 23 that overlaps vertically between the pair of opposing plate portions 27a and 27b of the vice clamp portion 27 and the corresponding plate-like portion 11b of the frame 11 are firmly sandwiched by screw tightening force. And clamp in a tightened state like a vise.

  Such a tightening operation can be executed as a tightening operation of the nut 28b from the upper side, for example, with one side of the vehicle left-right direction first and the other side of the vehicle left-right direction rearward.

  Next, the operation will be described.

  In the mounting component fixing structure of the present embodiment configured as described above, the plate-like portion 11b of the frame 11 on the chassis side is sandwiched by a strong pressure contact force due to screw tightening in the vice clamp portion 27 of the clamp bracket 25. The corresponding mounting plate 23 on the mounting component 20 side that is tightened and coupled to the mounting side coupling portion 26 of the clamp type bracket 25 is securely fixed to the frame 11 via the clamp type bracket 25.

  Therefore, in this embodiment, it is not necessary to form bolt holes or notches for fastening on the upper plate-like portion 11b or the vertical plate-like portion 11d of the frame 11, and a plurality of bolts or the like are attached to a plurality of mounting holes. And there is no need to adjust the mutual fastening position, fastening order, etc. of a plurality of bolts and the like mounted in a plurality of mounting holes. Therefore, it is possible to use the clamp bracket 25 having high versatility without causing a reduction in rigidity and cost of the frame 11 and having a wide common range without any limitation of the mounting hole.

  Moreover, the mounting position of the clamp bracket 25 corresponding to the panel-like fixed portion 24 of the mounting component 20 can be set at an arbitrary position in the vehicle front-rear direction with respect to the plate-like portion 11 b of the frame 11. Assembling workability can be remarkably improved, and the degree of freedom in designing the mounted component 20 and its peripheral components can also be increased.

  Moreover, in this embodiment, the fastening part 27d in the vise clamp part 27 of the clamp type bracket 25 is folded back with one of the male and female screw coupling parts 28a held in a non-rotating state on one end side of the folded part 27c. Since it has either the male or female screw coupling portion 28b screwed to one screw coupling portion 28a while being in contact with the outer surface 27f on the other end side of the shape portion 27c, one screw coupling to the vice clamp portion 27 in advance. Only the portion 28a can be held, or the other screw coupling portion 28b can be screw-coupled to the non-tightened position with respect to the one screw coupling portion 28a. Therefore, the assembling workability of the clamp bracket 25 itself is very good.

  Further, in the present embodiment, one screw coupling portion 28a is constituted by a bolt that is movably held in the width direction of the plate-like portion 11b of the frame 11 with the head portion 28h being prevented from rotating on one end side of the folded-back portion 27c. The other screw coupling portion 28b is composed of a nut that is screw-coupled to the bolt while contacting the other end side outer surface 27f of the folded-back portion 27c. Therefore, the bolt can be held in advance at a height position close to the final fastening posture, the fastening posture of the screw coupling portions 28a and 28b can be stabilized, and a stable clamping state in the vise clamp portion 27 can be ensured.

  Further, in the tractor 1 of the present embodiment, the panel 22 of the mounting component 20 is provided between the left and right rail-shaped components 11A on the vehicle front side with respect to the coupler 12 for traction connection, and the lower frame 11 side is provided by the panel 22. The wiring parts 5 and the upper connecting pipes 5 connected to the trailer 2 are accurately separated in the vertical direction. Therefore, even if the connecting piping 5 has a length sufficient to accommodate various trailers 2, the connecting piping 5 interferes with the routing components on the frame 11 side or between peripheral components. It can be prevented from being damaged by being pinched.

  In the above-described embodiment, the mounting plate 23 may be provided with a small-diameter guide hole 23h or the like that can be positioned at a predetermined position with respect to the frame 11. However, as shown in FIG. A positioning set plate 29 capable of contacting the vertical plate-like portion 11d of each rail-like component 11A of the frame 11 may be provided integrally, or a set plate 29 capable of positioning the mounting plate 23 on the frame 11 side. You may provide integrally.

  The clamp bracket 25 described above has the mounting side coupling portion 26 that integrally screw-couples the upper portion of the main body portion 25P to the side plate portion 23a of the mounting plate 23. If 23 is not provided, the shape can be different. For example, when the panel-like fixed portion 24 of the mounting component 20 is supported using a plurality of beams 31 as shown in FIG. 6, the mounting-side coupling portion 26 of the clamp bracket 25 that supports the beams 31 has the beam 31 on the bottom surface. A bending support plate portion 26t that is bent at a right angle inward in the vehicle width direction may be provided so that an upward male screw portion 26c can be installed while being supported from the side. Needless to say, in the case of a mounting component that is not in the form of a panel, an arbitrary coupling form of the mounting side coupling portion 26 that conforms to the mounting component can be considered.

  Further, although the above-described clamp bracket 25 is mounted on the plate-like portion 11b of the frame 11 from the inner side in the vehicle width direction, the mounting direction may be another direction, and the mounting posture thereof. Of course, may be inclined instead of horizontal.

  As described above, the present invention can use a bracket with high versatility, and can improve the mounting workability of the mounting component without lowering the rigidity of the support member and increasing the cost. It is also possible to provide a vehicle having the same structure, and is useful for a vehicle in general, such as a fixed structure for fixing a vehicle mounting component to a support member on the chassis side via a bracket, and a towing vehicle having the same structure.
