  • Patent number: 10099728
    Abstract: A work vehicle has a cabin supported via an anti-vibration member to a bracket that extends to a vehicle body outer side from a vehicle body frame. The bracket mounts a weight member. The weight member is attached to a position in the bracket, said position being located outward of the anti-vibration member, with the weight member protruding to the vehicle body outer side from the bracket.

  • Patent number: 9725018
    Abstract: A seat device includes a seat part that is capable of changing a posture to a use posture that allows sitting on the seat part and to a non-use posture that does not allow sitting on the seat part. A seat support can support the seat part in a state in which the seat part has been changed to the use posture. A guide member has a free groove that slidably guides a sliding part of the seat support and a regulation groove that regulates sliding of the sliding part in a state in which the seat part has been changed to the use posture. The guide member can be fixed on the seat part. A spring biases the seat support so that the sliding part is held in the regulation groove in the state in which the seat part has been changed to the use posture. A lever may cause the sliding part to slide from the regulation groove to the free groove and allow the seat support to swing downward.

  • Patent number: 8807265
    Abstract: A tractor includes: a driver's compartment; an engine compartment; a partitioning member that partitions the driver's compartment and engine compartment and has a through-hole; a steering wheel provided in the driver's compartment; a power steering unit disposed on the engine compartment side; a steering shaft that extends from the steering wheel and is connected to the power steering unit; an elastic sealing member provided in an inner circumferential portion of the through-hole; and an anti-vibration member. The elastic sealing member includes a supported portion supported to the inner circumferential portion and a ring-shaped lip portion protruding downward from one end of the supported portion. The power steering unit is mounted to the partitioning member via the anti-vibration member, the ring-shaped lip portion is elastically clamped to the upper face of the power steering unit, and the steering shaft is connected to the power steering unit while inserted in the through-hole.
