Is connected by a hydraulic cylinder 3 so that the waist can be bent and steered freely.
The front vehicle body 1 is provided with a shovel device in which a bucket 6 is rotatably mounted by a hydraulic cylinder 7 on an arm 5 which is vertically swingable by a hydraulic cylinder 4, and a driving portion 8 and a driving portion 9 are provided on a rear vehicle body 2. A wheel loader with a backhoe, which is an example of a work vehicle, is configured by being provided in a state of being covered with the cabin 10 and by being detachably provided with a backhoe device 13. Swing-type door 10 for opening / closing the entrance / exit for the driver's part 8
a and a wall portion 10b located laterally outside of the driving portion 9 and behind the door 10a are provided in the cabin 10, and as shown in FIG. 2, slide rails 12 slide back and forth on upper and lower fixed rails 11 respectively. Freely attached, the wall portion 10b is attached to the slide rail 12, the door 10a is integrally slidably and swingably attached to the wall portion 10b, and the wall portion 10b can be opened / closed together with the door 10a in an openable state. Then, the wall portion 10b is opened together with the door 10a to form a wide opening so that the maintenance work of the driving portion 9 can be easily performed.

退揺動により破損しないように構成してある。To form the backhoe device 13, a swing bracket is attached to a mounting frame having an operating portion and a pair of left and right outriggers 13a so as to be rotatable left and right by a hydraulic actuator, and a boom is freely swingable up and down by a hydraulic cylinder. Attached to a swing bracket, an arm 13b attached to a boom so as to be swingable by a hydraulic cylinder, a bucket 13c attached to an arm 13b so as to be rotatable by a hydraulic cylinder, and a chain 15 with a hook 14 attached to an upper portion of an outrigger 13a. Thus, the backhoe device 13 in the retracted posture, which is moved to the cabin 10 side, is configured to be steady by the chain 15 in which the hook 14 is hooked on the arm 13b. Step 16 for entrance / exit
3, the left and right plate-shaped suspension members 16a are swingably attached to the rear body 2 around the support shafts 16b, and the lower ends of both suspension members 16a are relatively swingable around the support shafts 16c. The step plate 16d is attached to the step 16 so that the step 16 will not be damaged by the backward swinging motion around the support shafts 16b and 16c even if the step 16 collides with another object during traveling.
