(1) For example, when the vehicle 1 is loaded on a truck and transported, if the overall height of the vehicle 1 needs to be lowered, the lower support members 31 and 33 and the upper support members 32 and 34 are divided into heads. By removing the guard 12, the overall height of the vehicle 1 can be easily reduced. Further, the upper support members 32 and 34 separated from the lower support members 31 and 33 can be transported together with the head guard 12 without being bulky. Therefore, it is not necessary to remove the support column 13 from the vehicle body 10 or to separate the head guard 12 and the support column 13. Therefore, it is possible to provide the vehicle 1 that can be easily transported by removing the head guard 12 by a simple operation of dividing the lower support members 31, 33 and the upper support members 32, 34.

  (2) Since a general bolt is not used for the connection between the lower support members 31 and 33 and the upper support members 32 and 34, the work of dividing the lower support members 31 and 33 and the upper support members 32 and 34 is performed without a tool. Can be done.

  (3) Since the lower support members 31, 33 and the upper support members 32, 34 are connected in the vertical direction by fitting the fitting portions 40 to each other, the lower support members 31, 33 and the upper support members 32, 34 can be temporarily fixed before being fixed by the support material fixing structure S.

  (4) Since the protruding portion 41 and the covering portion 42 constituting the fitting portion 40 each have a cylindrical outer peripheral surface 41a and a cylindrical inner peripheral surface 42a (curved surface) at least partially in contact with each other, the fitting is in contact with each other. Shaking caused by the dimensional tolerance of the portion 40 can be reduced.

  (5) Since the fixing structure 5 includes the holding members 51 to 54 that are screwed into the upper support member 32 to hold the lower support member 31, the upper support member 32 extends in the left-right direction and the front-rear direction with respect to the lower support member 31. It can regulate movement. Further, since the fixing structure 6 includes clamping members 61 and 62 that are screwed into the upper support member 34 to hold the lower support member 33, the upper support member 34 is restricted from moving in the left-right direction with respect to the lower support member 33. it can. Further, the strength of the head guard 12 that protects the operator from falling objects is not impaired.

  (6) Since the fixing structure 6 includes the penetrating member 63 that penetrates the lower support member 33 and the upper support member 34 in the front-rear direction, the upper support member 34 can be restricted from moving in the vertical direction with respect to the lower support member 33. .

  The present invention is not limited to the above embodiment, and the above configuration can be changed as appropriate. For example, the embodiment described above may be modified as follows, and the following modifications may be combined as appropriate.

-As long as two connected support | pillar materials can be fixed, you may change suitably a support | pillar material fixing structure. Further, for example, the front support 30A, the 30B, in place of the struts fixed structure S shown in FIG. 3 (A), may be provided struts fixed structure S shown in Figure 3 (B). Also, the strut member fixing structures S provided on the front struts 30A and 30B may be different from each other, and the strut member fixing structures S provided on the rear struts 30C and 30D may be different from each other.

  -You may change suitably the number of the support | pillars 13 which support the head guard 12. FIG. That is, the vehicle with a head guard may be provided with a large number of struts as long as the two strut members can be connected to each other and can be divided in the vertical direction. Moreover, it is not necessary for all the support columns to be provided with the support material fixing structure.

  -You may apply this invention to vehicles other than a counterbalance forklift. That is, the present invention can also be applied to reach forklifts and other cargo handling vehicles including a head guard.
