As a result, in the transmission portion 237 of the auxiliary transmission operation mechanism 230, the peripheral portion of the connection portion 237c, which requires relatively high maintenance, can be exposed through the opening 290 (second opening 292), which makes it easy. It can be configured so that it can be inspected and maintained.

Further, in the present embodiment, the front surface and the left surface of the side surface portion 270 are shaped so as to spread downward in the horizontal direction. As a result, the opening 290 can be opened not only in the front view and the side view but also in the plan view. This makes it possible to inspect and maintain the inside of the accommodating portion 280 via the opening 290 in a plan view.

The cover portion 293 shown in FIG. 10 closes the opening portion 290. The cover portion 293 has a shape corresponding to the opening portion 290. The cover portion 293 constitutes the front surface and the left surface of the side surface portion 270 in a state where the opening 290 is closed. In a state where the opening 290 is closed by the cover portion 293, the surface of the cover portion 293 and the peripheral surface of the opening portion 290 in the side surface portion 270 are made flush with each other.

Next, the voice input unit 300 will be described with reference to FIGS. 17 to 19.

The voice input unit 300 can input voice. The voice input unit 300 is provided in the accommodating unit 13a of the ceiling unit 13. Specifically, the voice input unit 300 is provided on the top portion formed by the left surface, the front surface, and the lower surface of the accommodating unit 13a. The voice input unit 300 is connected to a predetermined communication device such as a mobile phone via a predetermined cable provided in the tractor 1. As a result, the driver can make a call while driving the tractor 1. The voice input unit 300 includes a fixing unit 310, a sound collecting unit 320, and a joint unit 330.

The fixing portion 310 shown in FIG. 19 is a portion fixed to the accommodating portion 13a. The fixing portion 310 is fixed to the corner portion formed by the front surface and the lower surface of the accommodating portion 13a. The fixed portion 310 has a shape corresponding to the corner portion.

The sound collecting unit 320 is a portion capable of collecting sound. The sound collecting unit 320 is provided so as to face the seat 16 side. Specifically, the sound collecting unit 320 is provided so as to point diagonally to the lower left. A cable 321 capable of transmitting an electric signal is connected to the sound collecting unit 320. One end of the cable 321 is connected to the sound collecting portion 320, and the other end is accommodated inside the accommodating portion 13a.

The joint portion 330 is a portion that connects the fixed portion 310 and the sound collecting portion 320. The joint portion 330 constitutes a ball joint whose directivity direction of the sound collecting portion 320 can be adjusted.

As shown in FIG. 7, the voice input unit 300 configured as described above is arranged on the right side (side console 200 side) of the seat 16. The voice input unit 300 overlaps with the front side region 210A of the side console 200 in a plan view. Further, the voice input unit 300 is located between the through hole 221 of the front loader operation mechanism 220 and the guide hole 231a of the auxiliary transmission operation mechanism 230 in the front-rear direction. Further, as shown in FIG. 17, the voice input unit 300 is located behind the front end portion of the side console 200 and in front of the seat base portion 12b.

As a result, voice can be suitably input via the voice input unit 300. That is, during the operation of the tractor 1, the driver often visually recognizes the side (right side) where the side console 200 is located. Therefore, by arranging the voice input unit 300 as described above, it is possible to suitably input voice through the voice input unit. Further, since the voice input unit 300 is provided on the ceiling unit 13, the voice input unit 300 can be located at a position where it is relatively difficult to input noise.

Further, since the voice input unit 300 is provided in the accommodation unit 13a, the voice input unit 300 can be arranged in a concentrated manner with the audio equipment 13b and the air conditioning equipment 13c arranged in the accommodation unit 13a. Further, the other end of the cable 321 connected to the sound collecting portion 320 can be easily wired inside the accommodating portion 13a. Further, since the voice input unit 300 is provided at the top of the accommodating unit 13a, it is possible to prevent the voice input from being disturbed by objects arranged around the accommodation unit 13a.
