がある。 BACKGROUND ART Conventionally, some construction machines such as bulldozers have a protection device installed above the operator's cab in order to protect the driver in the case of overturning or falling. In addition, some of the above-mentioned protection devices combine the main body and the operation so that they can be flipped backwards at the same time when servicing the car body, etc. However, in the driver's cab and protection device with the above structure, there is Since there is no buffering function, vibrations from the vehicle body are transmitted directly to the driver's cab, resulting in problems such as uncomfortable riding and high noise levels in the driver's cab. In order to improve this, it is possible to interpose a buffer between the protective device and the vehicle body to buffer vibrations before they are transmitted to the driver's cab, but it is also possible to interpose a buffer between the protective device and the vehicle body. If the vehicle body falls over, there is a risk that the protective device may not provide sufficient protection.

The following support rods 14, 15, 16, 17, and 18 are provided between the frame-like frames 6 and between the driver's cab 4 and the vehicle body 1. That is, support rods 14 and 15 facing in the advancing direction are provided between the bottom of the driver's cab 4 and the lower part of the frame-like frame 6, and between the upper part of the driver's cab 4 and the upper part of the frame-like frame 6.
supports the load and pitching of the driver's cab 4 in the longitudinal direction, and is provided between the front bottom of the driver's cab 4 and the vehicle body 1 and between the driver's cab 4 and the lower part of the frame 6 so as to be perpendicular to the traveling direction of the vehicle body 1. Support rod 16 provided in
and 17 are designed to support the load and yawing of the driver's cab 4 in the left and right direction. Further, a support rod 18 is provided between the upper part of the driver's cab 4 and the upper part of the frame-like frame 6 so as to be perpendicular to the traveling direction of the vehicle body 1.
The rolling movement of the driver's cab 4 is supported by the support rods 17.

行なえる。 As described in detail above, in this invention, the driver's cab 4 is elastically supported by the frame 6 of the protector main body 5 which is tiltable with respect to the vehicle body 1 via the buffer member 13, so that vibrations from the vehicle body 1 are reduced. The buffer member 13
Because it is buffered by and is not transmitted to the driver's cab 4,
In addition to improving the ride comfort and reducing noise inside the driver's cab 4, the protection device body 5 is directly attached to the vehicle body 1.
Since it is connected to the side, the protective function when the vehicle body 1 falls is not impaired in any way. In addition, since support rods 14 are arranged vertically and horizontally between the driver's cab 4, the main body 5, and the vehicle body 1, the load of the driver's cab 4 is transferred to these support rods 14...
... is supported, thereby preventing the driver's cab 4 from swinging unstablely. Moreover, since the main body 5 can be reversed together with the driver's cab 4, maintenance of the vehicle body 1 etc. can be easily performed.
