  However, the lifting step is inserted into the closing, and the lifting step is assembled to the bracket via the closing. There is a problem that is difficult to match.

  Since the lifting step is made of aluminum and the closing is made of a painted resin or the like, there is also a problem that if the positioning cannot be easily performed at the time of assembling, the coating film of the closing may be damaged.

  Therefore, an object of the present invention is to solve the above-described problem and to provide an assembling structure of a lifting / lowering step that can easily be aligned in a height direction when the lifting / lowering step is fixed to a bracket via closing. is there.

  In order to achieve the above object, the present invention provides a pair of brackets at a lower portion of a cab body side, a box-like closing is attached between the brackets, and a lifting step is inserted into the closing and both ends of the lifting step are mounted. In an assembling structure of an elevating step for fixing a portion to the bracket through an opening formed in a side wall of the closing, the closing is in contact with a lower surface of the elevating step to define an assembling position to the bracket. An assembling structure of a step for raising and lowering, comprising a height regulating member.

  The height regulating member is formed on one of the side walls of the closing, and the mounting portion at one end of the elevating step is temporarily fixed to a corresponding bracket with a bolt, and the mounting portion at the other end is In the height regulating member, the ascending / descending step is inserted into the closing up to the attaching position while the assembling position is defined, and a bolt is screwed into the attaching portion from the bracket side, and the ascending / descending step adjusts the closing. It is preferable to be assembled to the bracket via a bracket.

  Between the side walls of the closing, there is a cross-member connected between the side walls and located at the lower front edge of the step for raising and lowering, and the side walls of the closing located on both sides of the cross-member include An opening for contacting the mounting portion of the step with the bracket is formed, and the height regulating member is formed on the upper surface of the cross member located on the side wall side, and is in contact with the lower surface of the elevating step. It is preferable that the mounting portion be made of a rib that matches the mounting height of the mounting portion to the bracket.

  It is preferable that a plurality of the ribs are formed on the upper surface of the crosspiece member and are formed so as to extend along the loading direction of the elevating step.

  The present invention facilitates the assembling work by forming a height regulating member that regulates the mounting height in the closing when assembling the ascending and descending steps to the bracket via the closing, so that accurate positioning can be performed. An excellent effect of being able to be exhibited.

In the present invention, it is an assembly exploded perspective view when assembling the steps for closing and elevating to the bracket on the cab body side. In the present invention, details of assembling the ascending / descending step by inserting the ascending / descending step into the closing are shown, wherein (a) is a perspective view of an essential part of an assembling part, and (b) is a sectional view of the essential part after assembling. . It is a plane sectional view at the time of assembling the raising / lowering step in this invention.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

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

  Bolt holes 24, 24 are formed in the closing 12, and screw holes 25, 25 are provided in the lower edges of the brackets 11f, 11b and the cab body side 10, and the closing 12 is fitted between the brackets 11f, 11b. At this time, a bolt (not shown) is inserted between the bolt holes 24 and screwed into the screw holes 25 to be mounted between the brackets 11f and 11b.

  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 lower side of the front edge of the step 14 for elevating and lowering. And two upper and lower crosspiece members 29 located therein.

  Openings 31 are formed in the side walls 28f and 28b so that the mounting portions 30 (see FIGS. 2 and 3) formed at both ends of the elevating step 14 are inserted into the side walls 28f and 28b so as to contact the brackets 11f and 11b. 27 is formed with a horizontally elongated slot 33 into which a positioning projection 32 (see FIGS. 1 and 3) formed at the rear of the elevating step 14 is fitted.

  Bolt holes 37 are formed in the brackets 11f and 11b for inserting the lifting step 14 into the closing 12 and screwing the bolts 38 into the mounting portion 30 inserted through the opening 31.

  According to the present invention, one of the cross members 29, in particular, the cross member 29 on the side wall 28b located on the vehicle rear side of the closing 12 is brought into contact with the lower surface of the lifting / lowering step 14, and is attached to the bracket 11b. Is provided with a height regulating member 35 which defines the following.

  The height regulating member 35 is configured by a plurality of ribs 36 provided on the crosspiece member 29 as shown in an enlarged manner in a portion surrounded by a circle D in FIG.

  The base 29b of the cross member 29 connected to the rear side wall 28b is formed to extend rearward (backward), and the height regulating member 35 has, for example, three ribs 36 on the base 29b, which will be described later. It is formed and configured to extend along the loading direction of the lifting step 14.

  The height regulating member 35 composed of the rib 36 is provided with the lifting step 14 inserted into the closing 12, and when the lower surface of the lifting step 14 is placed on the rib 36 as shown in FIG. The height of the elevating step 14 at the time of loading is defined so that the bolt hole 37 of 11b and the screw hole of the mounting portion 30 match.

  The assembling of the lifting step 14 according to the present invention will be described.

  In order to assemble the elevating step 14 to the brackets 11f and 11b via the closing 12, the elevating step 14 is fitted into the closing 12, and either one of the side walls of the elevating step 14 is used. After the mounting portion 30 on the side is inserted into the opening 31 of the side wall 28f, it is temporarily fixed to the bracket 11f with a bolt 38 so that the rear end side of the elevating step 14 can move back and forth. By pushing the elevating step 14 along the height regulating member 35 composed of the rib 36, the rear projection 32 fits into the elongated hole 33 of the rear wall 27, and thereby the elevating step 14 in the closing 12 is formed. Is determined in the horizontal direction and the height direction, thereby determining the positions of the rear mounting portion 30 and the bolt holes 37 of the rear bracket 11b. By screwing the bolt 38 to the mounting portion 30 through the hole 37, the elevating step 14, it is possible to assemble the bracket 11f, 11b via the closing 12.

  When assembling the elevating step 14, the mounting portion 30 is inserted into the opening 31 formed in the side walls 28f and 28b of the closing 12, and is fixed by being bolted with the bolt 38.
