A work vehicle, comprising: a vehicle body; a plurality of traveling devices located on both right and left sides of the vehicle body; a plurality of bending link mechanisms that support the respective traveling devices on the vehicle body such that the traveling devices can be individually raised or lowered; and a plurality of drive mechanisms capable of individually changing posture of the bending link mechanisms; the drive mechanisms being able to change the posture of the bending link mechanisms while maintaining a state in which intermediate bending portions of the bending link mechanisms bend toward an intermediate side in a front-rear direction of the vehicle body; characterized in that each of the bending link mechanisms includes a first link having one end supported on the vehicle body such that the first link is capable of swinging around a lateral axis, and a second link having one end supported on the other end of the first link such that the second link is capable of swinging around a lateral axis, with the traveling device supported on the other end of the second link, each of the drive mechanisms includes a first hydraulic cylinder capable of changing the swinging posture of the first link with respect to the vehicle body, and a second hydraulic cylinder capable of changing the swinging posture of the second link with respect to the first link, and each of the drive mechanisms changes the posture of the bending link mechanism while maintaining a state in which the first link and the second link in the bending link mechanism bend toward the intermediate side in the front-rear direction of the vehicle body. a vehicle body; a plurality of traveling devices located on both right and left sides of the vehicle body; a plurality of bending link mechanisms that support the respective traveling devices on the vehicle body such that the traveling devices can be individually raised or lowered; and a plurality of drive mechanisms capable of individually changing posture of the bending link mechanisms; the drive mechanisms being able to change the posture of the bending link mechanisms while maintaining a state in which intermediate bending portions of the bending link mechanisms bend toward an intermediate side in a front-rear direction of the vehicle body; characterized in that each of the bending link mechanisms includes a first link having one end supported on the vehicle body such that the first link is capable of swinging around a lateral axis, and a second link having one end supported on the other end of the first link such that the second link is capable of swinging around a lateral axis, with the traveling device supported on the other end of the second link, each of the drive mechanisms includes a first hydraulic cylinder capable of changing the swinging posture of the first link with respect to the vehicle body, and a second hydraulic cylinder capable of changing the swinging posture of the second link with respect to the first link, and each of the drive mechanisms changes the posture of the bending link mechanism while maintaining a state in which the first link and the second link in the bending link mechanism bend toward the intermediate side in the front-rear direction of the vehicle body.
