Next, the action of this embodiment will be described.

However, in the telescopic stacker 10, the width, length, shape, and the like of the pair of left and right telescopic legs 20 are designed and changed according to the use pattern, and there are many types of derivative vehicles having different types of leg portions 21. Here, even if the telescopic stacker 10 is of a different vehicle type, the travel drive unit 35 accommodated in the rear frame 31 has a plurality of common travel drive units 35 accommodated in the rear frame 31, and therefore is manufactured for each vehicle type. The necessity of different types of rear frames 31 is low.

Therefore, in the present embodiment, the rear frame 31 has the first connecting portion 31a and the opposing portion 33a that can function as a connecting portion that is coupled to the leg portion 21 by the screws 41 and 42. According to this configuration, even if a plurality of different types of leg portions 21 are present depending on the use form, the first connecting portion 31a and the opposing portion 33a of the rear frame 31 can be coupled to the respective leg portions 21 by the screws 41 and 42. The leg portions 21 and the rear frame 31 are respectively coupled.

The first connecting portion 31a is coupled to the first connecting portion 21a in the vertical direction by the screw 41, and the relative position of the leg portion 21 and the rear frame 31 in the vertical direction is positioned. Therefore, for example, the situation in which the leg portion 21 and the rear frame 31 are displaced in the vertical direction by the vertical movement of the telescopic stacker 10 during traveling can be suppressed. In addition, since the first connecting portion 31a and the first connecting portion 21a are connected to each other in the vertical direction by the screw 41, the vertical connecting force caused by the vertical vibration can be the first connecting portion 31a and the first connecting portion. The contact area of 21a is tolerated.

The opposing portion 33a is coupled to the extending portion 22 in the front-rear direction by the screw 42, and the leg portion 21 and the rear frame 31 are positioned in the front-rear direction. Therefore, for example, when the telescopic stacker 10 vibrates in the front-rear direction generated during traveling, the relative position of the leg portion 21 and the rear frame 31 in the front-rear direction can be suppressed. Further, since the opposing portion 33a and the extending portion 22 are coupled by the screw 42 in a state of being in contact with each other in the front-rear direction, the front-rear direction force generated by the vibration in the front-rear direction can be contacted by the opposing portion 33a and the extending portion 22. The part is to withstand.

In the leg portion 21, by providing the first connecting portion 21a and the second connecting portion 21b, the pair of right and left telescopic legs 20 are moved toward each other in the direction away from the direction of separation.

In the above embodiment, the following effects can be obtained.

(1) The rear frame 31 has a first connecting portion 31a and an opposing portion 33a that are coupled to the leg portion 21 by screws 41 and 42. According to this configuration, even if a plurality of different types of leg portions 21 exist in accordance with the use form, the first connecting portion 31a and the opposing portion 33a of the rear frame 31 can be coupled to the respective legs by the screws 41 and 42. In the portion 21, the leg portions 21 and the rear frame 31 are coupled to each other. Therefore, it is not necessary to manufacture different types of rear frames 31 for each different vehicle type, and the rear frame 31 can be generalized, and the manufacture of the telescopic stacker 10 can be facilitated.

(2) The rear frame 31 has the first connecting portion 31a as a connecting portion, and the first connecting portion 21a overlaps with each other in the vertical direction, and is connected to the first connecting portion 21a in the vertical direction by the screw 41. . According to this configuration, the first connecting portion 31a is coupled to the first connecting portion 21a in the vertical direction by the screw 41, and the leg portion 21 and the rear frame 31 can be positioned in the vertical direction. Therefore, for example, when the telescopic stacker 10 vibrates in the vertical direction during traveling, the relative position of the leg portion 21 and the rear frame 31 in the vertical direction can be suppressed. In addition, the first connecting portion 31a and the first connecting portion 21a are connected by the screw 41 in a state of being in contact with each other in the vertical direction. Therefore, the vertical force acting in the vertical direction can be caused by the first connecting portion 31a and the first connecting portion. The contact area of 21a is tolerated.

(3) The rear frame 31 has the opposing portion 33a as a connecting portion which is overlapped with the extending portion 22 in the front-rear direction and is coupled to the extending portion 22 in the front-rear direction by the screw 42. According to this configuration, the opposing portion 33a is coupled to the extending portion 22 in the front-rear direction by the screw 42, and the relative positions of the leg portion 21 and the rear frame 31 in the front-rear direction can be positioned. Therefore, for example, the relative positional deviation of the leg portion 21 and the rear frame 31 in the front-rear direction due to the vibration in the front-rear direction generated during the traveling of the telescopic stacker 10 can be suppressed. Further, since the opposing portion 33a and the extending portion 22 are coupled by the locking member in a state of being in contact with each other in the front-rear direction, the front-rear direction force generated by the vibration in the front-rear direction can be caused by the opposing portion 33a and the extending portion 22 The contact area is to withstand.

(4) The upper frame 15 is coupled to the leg portion 21 and the rear frame 31 by screws 43 and 44. Therefore, for example, it is conceivable that at least one of the leg portion 21 and the rear frame 31 is coupled to the upper frame 15 by welding, and at least one of the leg portion 21 and the rear frame 31 is pre-modulated into a set of components. . In this case, for example, when it is necessary to change the design of the leg portion 21 or the rear frame 31 in response to different vehicle types, there is a case where the design of the upper frame 15 has to be changed. Therefore, by attaching the upper frame 15 to the leg portion 21 and the rear frame 31 by means of the screws 43, 44, it is not necessary to manufacture different types of upper frames 15 for each different vehicle type, so that the upper frame 15 can be made. It is generalized and the manufacture of the telescopic stacker 10 is facilitated.

(5) The leg portion 21 includes a first connecting portion 21a and a second connecting portion 21b that connect the pair of left and right telescopic legs 20 to each other. According to this configuration, the strength can be maintained by the first connecting portion 21a and the second connecting portion 21b, and the pair of left and right telescopic legs 20 can be prevented from moving toward each other in the direction away from each other. Therefore, for example, the widths of the pair of right and left telescopic legs 20 are easily maintained at a predetermined width.

(6) For example, in the case where the leg portion 21 and the rear frame 31 are coupled by welding, after the leg portion 21 and the rear frame 31 are welded, the traveling drive portion 35 must be housed in the rear frame 31, so that the telescopic type is used. The assembly sequence of the stacker 10 imposes constraints. However, according to the present embodiment, since the rear frame 31 can be coupled to the leg portion 21 while the traveling drive unit 35 is housed in the rear frame 31, the assembly order of the telescopic stacker 10 can be prevented from being restricted. .

(7) For example, in the case where the leg portion 21 and the rear frame 31 are joined by welding, and the leg portion 21 and the rear frame 31 are pre-modulated into a set of components, the module is formed into a leg of a set of components. The 21 and the rear frame 31 are entirely placed in a painting apparatus for painting, so that a large painting apparatus is required. However, according to the present embodiment, since the leg portion 21 and the rear frame 31 can be placed in the painting equipment and then the leg portion 21 is coupled to the rear frame 31, the large-sized painting is no longer required. Equipment to suppress equipment costs.

Further, the above embodiment can be modified as follows.

○ As shown in FIG. 5, each of the first connecting portions 31a may be overlapped with the second connecting portion 21b in the vertical direction, and the second connecting portion 21b may be coupled to the second connecting portion 21b in the vertical direction by the screw 41.
