<4. Fixing the mudguard with the bracket>
Next, with reference to each figure, the process of fixing the mud guard 17 to the side frame 21 using the bracket 19 will be described.

  First, the cab rear member 23 and the first stay portion 191 are prepared. The first screw fastener B1 is passed through each of the through holes formed in the first base end portion BP1 and positioned in the screw hole formed in the rear surface RS1 of the lower end portion EP1, and then the first stay is used using a tool. The portion 191 is fastened and fixed to the cab rear member 23.

  Next, the fourth screw fastener B4 is passed through each of the through holes in the front and rear projecting portions of the cab rear member 23 and positioned in the screw holes formed in the outer surface SS1 of the side frame 21, and then the tool The cab rear member 23 is fastened and fixed to the side frame 21 using

  Next, the second stay part 193 is prepared. The second stay part 193 sandwiches the cab rear member 23 together with the first stay part 191 from the front of the cab rear member 23. In that state, the second screw fastener B2 is passed through each of the through holes in the second base end portion BP3 and positioned in the screw holes formed in the outer surface SS1, and then the second stay portion is used using a tool. 193 is fastened and fixed to the side frame 21.

  Next, the second tip portion TP3 of the second stay portion 193 is overlaid on the first tip portion TP1 of the first stay portion 191. In that state, after the third screw fastener B3 is passed through each of the through holes formed in the both, the tip portions TP1 and TP3 are fastened and fixed using a tool.

  Next, the mud guard 17 is attached to the frame portion 195. The attachment of the mudguard 17 is not a main part of the present disclosure, and a known technique can be applied, and thus the description thereof is omitted.

<5. Action and effect of bracket>
As described above, various parts are attached to the side frame 21. On the outer side surface SS <b> 1 of the side frame 21, a relatively wide working space exists in front of the cab rear member 23 until the mud guard 17 is attached. On the other hand, an engine mount or the like may protrude further laterally than the outer surface SS1 behind the cab rear member 23 on the outer surface SS1, and there may be only a small work space.

  However, according to the bracket 19 of the present disclosure, the first stay portion 191 is fixed to the rear surface RS1 of the cab rear member 23 before the cab rear member 23 is attached to the side frame 21. Therefore, the tool does not interfere with the engine mount or the like.

  Further, since the first stay portion 191 is first attached to the cab rear member 23, the first stay portion 191 and the cab rear member 23 can be collectively fixed to the side frame 21 even if an engine mount or the like is present.

  From the above, it is possible to provide the bracket 19 that can be easily fixed to the side frame 21.

  In addition, the first stay portion 191 is formed with a slit SL1 along a virtual line extending from the fourth screw fastener B4 to the left side of the vehicle V in parallel with the y-axis. The slit SL1 is bent together with the first stay portion 191 after extending toward the side of the vehicle V. Due to these features, the tool of the fourth screw fastener B4 is prevented from interfering with the first stay portion 191, so that the bracket 19 can be more easily fixed to the side frame 21.

  Further, the rigidity of the first stay portion 191 is reduced by providing the slit SL1. Therefore, since the first stay portion 191 is bent while the both ends TP1 and TP3 are fastened by the third screw fastener B3, the second tip TP3 is accurately seated on the surface of the first tip TP1.

  Further, by providing the rib LB1, it is possible to suppress the rigidity of the first stay portion 191 from being excessively reduced. Therefore, it is possible to suppress the mudguard 17 from vibrating while the vehicle V is traveling.

  The bracket of the present disclosure and the fixing method thereof are easy to fix to the side frame and are suitable for vehicle use.
