スに割れが生じるおそれが大である。(Problems to be solved by the invention) In the conventional structure described above, rain, wind, and the like from the front to the driver's seat side through the front opening formed by the front frame composed of the pair of left and right front columns and the top frame. However, there is a drawback in that dust or the like is blown into the operator to cause discomfort. Therefore, it is conceivable to attach the transparent glass that covers the front opening to the front frame.However, if the transparent glass is simply attached to the front frame by bolt fastening, each pillar vibrates due to the vibration of the tractor, and the vibration directly There is a high possibility that cracks will be generated in the transparent glass by being transmitted to the transparent glass.
そこで、本考案は上記問題点に鑑み、透明パネルの振動

る点にある。(Means for Solving the Problems) The technical means is to enclose the driver's seat 7 and to provide a pair of left and right front columns.
The left and right front pillars 12 and 12 have a pair of rear pillars 13, a four-column safety frame 2 having a top frame 14 that connects the upper ends of the pillars 12 and 13 and a canopy 15 that covers the upper side of the driver's seat 7. A transparent panel 19 that covers a front opening 18 formed between the left and right front columns 12 on a front frame 17 formed by 12 and the top frame 14.
Is attached via a plurality of panel mounting brackets 20 and a vibration isolator 26, and a cushion material 27 is inserted into an attachment hole 23 formed in the transparent panel 19 to bend in cooperation with the vibration isolator 26. In addition, the peripheral edge of the transparent panel 19 has a gap in the left and right front columns 12 and the ceiling frame 14.
