It tends to project outward from the position, and this tendency is particularly remarkable in the left foot. In addition, in the case of a driver having a large physique, when the foot pedal type parking brake operating member 29 is depressed, the upwardly raised thighs and knees tend to hit the round steering operation handle 32. Existence contributes to this trend.

On the other hand, the inclined surface g02 of the side column right side cover 21b of the side column 21 hits near the thighs, knees and shins of the driver sitting on the driver's seat 17, and the floor surface 19 faces forward. , The driver can slightly open the left and right legs to make the left knee, which tends to be particularly easy to project laterally, project laterally. Despite their existence, they do not have to feel cramped. When the foot pedal type parking brake operation member 29 is depressed, the thighs and knees raised upward are operated by being positioned between the round operation handle 32 and the front and rear inclined surfaces g02 and g03. The round operation handle 32 does not need to be hit.

In the present invention, when the driver sitting on the driver's seat 17 opens the legs slightly and assumes a natural posture, the inclined surface portion g02 substantially follows the thighs of the driver and is not used. The generation of the space is suppressed, while the reduction of the space inside the side column 21 is suppressed.
1 does not make it difficult to form the internal structure.

Although the information display surface f1 of the electronic display device f is not adapted to face directly backward and is somewhat adapted to the driver's seat 17 toward the driver's seat 17 side, the inclined surface portion g0 is conventionally provided.
2 tends to follow the side inclination of the electronic display device f,
Also in this respect, the generation of unused space is suppressed.

Further, in front of the space on the side of the side column 21 away from the floor surface 19 and in front of the steering column 23, the grain stalk raising device 10 and the raking device 11 of the cutting unit 3 are located. These are displaced by a certain distance in the left-right direction around the vertical axis x at the front end of the mowing main frame 14. In the space on the left side of the side column 21 and away from the floor surface 19, the rearward transport section 13 that does not require much space on the left and right is located. Therefore, the floor surface 19 from the front end of the side column 21 to the steering column 23
There is an unused space to the left of the side column.
The first half of “b” is located to achieve effective use of space.

The following effects can be obtained. That is, according to the first aspect, the specific portion of the front-rear side wall (the right side cover 21b of the side column) is positioned so as to be separated laterally from the driver's seat. Thus, the space existing on the side away from the driver's seat can be effectively used for expanding the driving space, and thereby the driving space can be expanded without increasing the body width.

According to the second aspect of the present invention, the shape of the driving space in the vicinity of the side wall in the front-rear direction in plan view is adapted to the mode of opening the legs of the driver sitting in the driver's seat. The degree is further improved.

According to the third aspect, the operating space can be expanded without increasing the floor width.
In addition, it is not necessary to change the machine base for this expansion.

According to the fourth aspect of the present invention, even in a combine which can be driven with the feeling of steering operation of a car, the driving space can be increased by suppressing an increase in the body width, and the driving space can be increased by the presence of the handle shaft. Even when the degree of leg opening of the driver increases, the shape of the driving space in the vicinity of the side wall in the front-rear direction can be rationally adapted to this leg opening mode to make the effective use of the space particularly remarkable.

According to the fifth aspect, the operating space can be expanded by effectively utilizing the space existing around the left and right sides of the backward transport section.

According to the sixth aspect of the present invention, the side body of the side column can be opened at a location near the space where the thigh, knee and shin of the driver sitting on the driver's seat are located.
