Therefore, the accommodation chamber 70 can be effectively used in consideration of the space occupied by the liquid tank 61 and the heat exchanger 62.
- the partition member 53 has a hole 130 through which the injection nozzle 82 can pass. Accordingly, the grease gun 80 is accommodated in the storage chamber 70 by operating the first cover member 55 to open the first opening 71K while the second opening 72K is closed without operating the second cover member 56. The work to be taken out from the storage room and the work to be stored in the storage chamber 70 can be performed. When performing the operation of taking out the grease gun 80 from the storage chamber 70 and the operation of storing it in the storage chamber 70, it is not necessary to operate both the first cover member 55 and the second cover member 56. Since only the opening / closing operation is required, complicated work is reduced.
- the main body 81 that is gripped by the operator in the work of taking out the grease gun 80 from the storage chamber 70 and the operation of storing it in the storage chamber 70 is disposed in the first storage chamber 71. Accordingly, the operation of taking out the grease gun 80 from the storage chamber 70 and the operation of storing it in the storage chamber 70 can be smoothly performed only by opening and closing the first cover member 55 without opening and closing the second cover member 56. Can do.
- the partition member 53 and the second holding member 120 are separated from each other, and a part of the injection nozzle 82 is not disposed inside the second holding member 120.
- the inside of the second holding member 120 is soiled with grease, if all of the injection nozzles 82 are arranged inside the second holding member 120, the grease may adhere to all of the injection nozzles 82 and become dirty. is there.
- a part of the injection nozzle 82 including the tip of the injection nozzle 82 is disposed inside the second holding member 120, and a part of the injection nozzle 82 is disposed outside the second holding member 120. Therefore, while maintaining the stable holding of the injection nozzle 82 by the second holding member 120, it is possible to suppress the expansion of the region where the injection nozzle 82 becomes dirty.
- the position of the opening 120 of the second holding member 120 and the position of the hole 130 of the partition member 53 are equal in the vertical direction.
- the operator can smoothly perform the operation of inserting the injection nozzle 82 into the opening 81 and the operation of pulling out from the opening 81 through the hole 130.
- the end surface of the opening 121 of the cylindrical portion 122 is inclined with respect to the central axis CX of the cylindrical portion 122.
- the opening 121 of the second holding member 120 is disposed in front of the bottom 123, and the position of the opening 121 and the position of the bottom 123 are different in the vehicle width direction.
- the cylindrical portion 122 is provided so as to incline to the right from the inner wall surface of the inner member 51 of the second storage chamber 72 toward the front.
- the bottom 123 of the second holding member 120 is disposed below the opening 121. Thereby, the grease inside the second holding member 120 can be accumulated in the bottom 123. Further, the grease inside the second holding member 120 is prevented from flowing out from the opening 121.
- FIG. 10 is a perspective view showing an example of the holding mechanism 100 according to the present embodiment.
- FIG. 11 is a side sectional view showing an example of the holding mechanism 100 according to the present embodiment.
- the second holding member 120 and the partition member 53 are separated.
- the partition member 53B and the second holding member 120B may be connected.
- the second holding member 120B has a cylindrical portion 122B and a bottom portion 123B. One end of the cylindrical portion 122B is connected to the partition member 52B.
- the operator smoothly inserts the injection nozzle 82 into the hole 130B, thereby smoothly moving the injection nozzle 82 to the second position. It can be held by the holding member 120B.
- the work vehicle is a hydraulic excavator, but is not limited to a hydraulic excavator.
- the holding mechanism 100 described in the above embodiments can be applied to all work vehicles on which the grease gun 80 is mounted.
