[0024] A cleaner 21 is provided behind the cockpit 5A to remove dust particles from the air blown in from the precleaner 20 and blow the air to the engine E.

[0025] As shown in Figures 4 and 5, a floor 30 on which the operator places his / her legs is provided in front of the cockpit 5A, and a storage compartment 31 is provided below the floor to store switches 41 such as a battery 40 that supplies power to the starter when the engine E is started and a battery cut-off switch that cuts off the battery 40 from the electrical system to prevent battery consumption.

[0026] The storage compartment 31 is formed by a front wall 31A, a left wall 31L, and a right wall 31R. The upper part of the storage compartment 31 is covered with a plate-shaped floor member 30A that forms the floor 30, and the rear part of the storage compartment 31 is open and connected to the front part of the engine room 6.

[0027] A pair of left and right openings (not shown) are formed at a predetermined interval in the left-right direction in the vertical middle of the front wall 31A. Also, a pair of front and rear openings 35 are formed at an upper part of the right wall 31R at a predetermined interval in the front-rear direction, and a pair of front and rear openings 36 are formed at a predetermined interval in the front-rear middle of the right wall 31R.

[0028] A step 32 used by an operator when boarding the control section 5 is supported in a retractable manner at the bottom of the right wall 31R of the storage compartment 31, and an opening 33 is formed in the right wall 31R of the storage compartment at a location facing the step 32. This allows the step 32 to be folded and stored inside the storage compartment 31 when not in use.

[0029] As shown in FIGS. 6 to 8, a battery 40 is provided in the front right part of the storage compartment 31 with its longitudinal direction aligned with the left-right direction of the storage compartment 31, and a switch 41 is provided below the battery 40.

[0030] 9, the support body 50 is formed of a substantially rectangular member on which the battery 40 is placed, and a pillar member 52 extending downward from the rear left part of the mounting member 51. It is preferable to provide a flexible sheet on the upper surface of the mounting member 51 to mount the battery 40 thereon.

[0031] The front part of the loading member 51 is formed with a front extension 51A extending upward from the front end, the rear part is formed with a rear extension 51B extending upward from the rear end, the left part is formed with a left extension 51L extending upward from the left end, and the right part is formed with a right extension 51R extending upward from the right end. This makes it possible to prevent the battery 40 from falling off the loading member 51.

[0032] The front extending portion 51A is formed with a pair of left and right openings 53 spaced a predetermined distance apart in the left-right direction, and the right extending portion 51R is formed with a pair of front and rear openings 54 spaced a predetermined distance apart in the front-rear direction.

[0033] 6 to 8, the front extension 51A is fixed to the rear surface of the front wall 31A by fastening means such as bolts inserted through the openings 36 and 54 of the front wall 31A, and the right extension 51R is fixed to the left surface of the right wall 31R by fastening means such as bolts inserted through the openings 36 and 54 of the right wall 31R. In addition, the lower part of the pillar member 52 is fixed to the machine frame 1. This makes it possible to form a space S below the mounting member 51 that cannot be easily seen from the outside. It is also possible to reduce vibrations transmitted from the machine frame 1 to the battery 40.

[0034] A locking member 55 extending in the left-right direction is provided on the upper side of the battery 40 and engages with the upper right portion of the battery 40. In a longitudinal cross section in the left-right direction, the locking member 55 is formed of an upper horizontal portion 55A extending in the left-right direction, an upper vertical portion 55B extending downward from the right end of the upper horizontal portion 55A, a lower horizontal portion 55C extending right from the lower end of the upper vertical portion 55B, and a lower vertical portion 55D extending downward from the right end of the lower horizontal portion 55C.

[0035] A pair of front and rear openings 56 are formed in the lower vertical portion 55D at a predetermined distance in the front-rear direction.

[0036] The locking member 55 is fixed to the left surface of the right wall 31R by fastening means such as a bolt inserted through the openings 35 and 56 of the right wall 31R. This further prevents the battery 40 from falling off the mounting member 51.

[0037] The switch 41 is disposed in a space S formed below the loading member 51, and is detachably fixed to the front wall 31A of the storage compartment 31 with a fastening means such as a bolt. This prevents an operator from accidentally operating the switch 41 and prevents a suspicious person from maliciously operating the switch 41. It also prevents rainwater from splashing on the switch 41 when the combine harvester is stored outdoors for a predetermined period of time. In this embodiment, the switch 41 is disposed in the space S, but it may also be disposed to the right of the operating lever 12 on the front panel 10, below the front panel 10, behind the mowing release lever 19 on the side panel 15, below the operator's seat 5A, on the right side of the cover of the engine compartment 6, or the like. Furthermore, combine harvesters are only operated during the autumn harvest season, and are stored in barns or other locations for long periods throughout the year. This causes dark current to flow to the vehicle body, resulting in discharge. To prevent this problem, switch 41 can be operated to cut off the flow of current to the vehicle body, thereby maintaining the storage capacity of battery 40.

[0038] As shown in FIG. 10 , a DC 12V output port 60, which receives power from the battery 40, is provided between the operator's seat 5A and the cleaner 21, and a plate-shaped stand 61 on which an electronic device such as a mobile phone can be placed is provided above the output port 60. This allows the electronic device to be placed on the stand 61 and its battery to be charged. A converter is connected to the output port 60. In this embodiment, the output port 60 is located between the operator's seat 5A and the cleaner 21, but it may also be located to the right of the operation lever 12 on the front panel 10, below the front panel 10, behind the mowing / removal lever 19 on the side panel 15, below the operator's seat 5A, on the right side of the cover of the engine room 6, or the like.
