Claims

[Scope of utility model registration request]

A cabin is installed on the vehicle body, extending from the panel box at the rear of the hood to the driver's seat located between the left and right rear wheel fenders, and the bottom side is covered with a mission cover that covers the step and mission case. In this tractor, a thick foam material is attached to the inner surface of the panel box via an uneven anti-vibration layer, an anti-vibration rubber plate is placed closely on the top of the step, and a fiber layer is lined on the anti-vibration rubber plate. Then, a wear-resistant rubber plate was placed on top of the sound-absorbing rubber plate, and two vibration-proof rubber plates and a sound-proof rubber plate were attached to the transmission cover, and the inside of the fender and A soundproof structure for a tractor cabin characterized by applying anti-vibration rubber plates or anti-vibration coating to the inside of the cabin frame.
