2. Description of the Related Art In general, in a working vehicle such as a combine or a tractor, a lever, a handle or a switch (direct operating unit) for directly operating the body and operating a working unit is provided to an operator on a front panel or a side panel of a driver seat. It is located at a position that is easy to see and operate. However, for example, in a combine harvester, switches the sensor for automatic control of the traveling direction when cutting from the center of the field, adjusts the amount of turning in the direction control, switches for self-checking various microcomputer functions, and the amount of operation for horizontal control of the aircraft. Indirect operation units (adjusters) that are not used directly by the operator during normal operation, such as adjustment and adjustment units of paddy sorters, etc., and are infrequently used, are covers that swing up and down around the driver's seat panel. Is provided, and the cover is closed during normal operation,
Open and operate as needed. In addition, Japanese Unexamined Utility Model Publication No. 58-110250 and 59-159 have a structure in which these indirect operation units, pilot lamps, and the like are mounted in an operation panel of a driver's seat and covered with a slide cover or a rotation cover.
Nos. 12,727, 55-129843 and the like are known.

[0003]

However, among the above-mentioned prior arts, in the cover that moves up and down, the operation of the indirect operation unit provided in the small space is hindered, or the arm or hand of the operator hits the operation. There were problems such as breakage or injury. In the case of a slide cover that slides open and close along the panel surface, rainwater, dust, dirt, etc. enter the cover and accumulate inside the cover, causing malfunctions of the adjusters and generally reducing the size of the adjusters. There are many inconveniences such as the necessity of using a special tool to remove and attach parts when replacing parts in the event of a failure in each part.

[0004]

The mounting structure according to the present invention for solving the above-mentioned problems is provided on an operation panel 6 of a driver's seat 2.
