  A mud fender 19 is attached to the lower part of the fender 17 so as to be positioned above the front tire 42.

  The lower portion of the front edge of the door 40 is formed with a recessed portion 43 recessed backward from the upper edge position of the bumper 45 so that the outer portion 20 continuous with the front side wall of the closing 12 described later is exposed from the recessed portion 43. Yes.

  Next, the closing structure of the lifting and lowering step according to the present invention will be described with reference to FIGS.

  In FIG. 1, a pair of brackets 11f and 11b are provided in front of the lower portion of the cab body 10, and a closing 12 formed in a box shape is attached between the brackets 11f and 11b.

  Bolt holes 24 and 24 are formed in the closing 12, and screw holes 25 and 25 are provided in the lower edges of the brackets 11 f and 11 b and the cab body 10, and when the closing 12 is fitted between the brackets 11 f and 11 b A bolt (not shown) is inserted into the bolt hole 24 and screwed into the screw hole 25 to be attached between the brackets 11f and 11b.

  Also, the closing 12 is formed with a clip hole 26 for clipping the front fender 15 of the fender 17 described with reference to FIG.

  The closing 12 connects the rear wall 27 located between the brackets 11f and 11b, the side walls 28f and 28b located inside the brackets 11f and 11b, and the side walls 28f and 28b, and at the lower part of the front edge of the elevating step 14. The upper and lower two-stage crosspiece members 29 are positioned.

  The side walls 28f and 28b are formed with openings 31 through which attachment portions 30 (see FIGS. 2 and 3) formed at both ends of the lifting step 14 are inserted to contact the brackets 11f and 11b. 27 is formed with a horizontally long slot 33 into which a positioning protrusion 32 (see FIGS. 2 and 3) formed at the rear part of the lifting step 14 is fitted.

  The brackets 11f and 11b are formed with bolt holes 37 for inserting the lifting step 14 into the closing 12 and screwing the bolts 38 into the mounting portions 30 inserted through the openings 31.

  In the present invention, as shown in FIG. 2, the front side wall 28 f is formed with an outer portion 20 that is continuous from the side wall 28 f and extends forward of the vehicle, and the blind cover 13 is provided on the outer portion 20. It is detachably provided so as to cover the front side wall 28f.

  A plurality of clips 22 are provided on the rear surface of the outer portion 20 in the vertical direction, and the blind cover 13 has an engagement piece 23 formed with an engagement hole 23a for fitting the clip 22 opposite the clip 22. Provided.
