A work vehicle comprising: a floor having a first insertion hole and a second insertion hole, the floor being provided for a foot of an operator being placed thereon; a forward pedal arm placed in the first insertion hole and provided with a forward pedal; a reverse pedal arm placed in the second insertion hole and provided with a reverse pedal; a forward rotation shaft oriented to tilt toward a rear of a vehicle body as approaching a laterally outside of the vehicle body, the forward rotation shaft serving as a rotation shaft of the forward pedal arm; a reverse rotation shaft oriented to tilt toward the rear of the vehicle body as approaching the laterally outside of the vehicle body, the reverse rotation shaft serving as a rotation shaft of the reverse pedal arm; a base portion attached to the floor and supporting the forward pedal arm, the reverse pedal arm, the forward rotation shaft, and the reverse rotation shaft; a coupling link configured to rotate in a first direction when receiving an operating force that rotates the forward pedal in a direction away from the operator, and configured to rotate in a second direction opposite to the first direction when receiving an operating force that rotates the reverse pedal in the direction away from the operator, wherein, when the forward pedal is rotated in the direction away from the operator, the operating force that rotates the forward pedal in the direction away from the operator is transmitted to the reverse pedal through the coupling link so that the reverse pedal rotates toward the operator, and wherein, when the reverse pedal is rotated in the direction away from the operator, the operating force that rotates the reverse pedal in the direction away from the operator is transmitted to the forward pedal through the coupling link so that the forward pedal rotates toward the operator; and a biasing member that biases the coupling link in the second direction when the coupling link rotates in the first direction, and that biases the coupling link in the first direction when the coupling link rotates in the second direction; and a transmission device configured to perform gear shift in accordance with an operating force applied to each of the forward pedal and the reverse pedal. a floor having a first insertion hole and a second insertion hole, the floor being provided for a foot of an operator being placed thereon; a forward pedal arm placed in the first insertion hole and provided with a forward pedal; a reverse pedal arm placed in the second insertion hole and provided with a reverse pedal; a forward rotation shaft oriented to tilt toward a rear of a vehicle body as approaching a laterally outside of the vehicle body, the forward rotation shaft serving as a rotation shaft of the forward pedal arm; a reverse rotation shaft oriented to tilt toward the rear of the vehicle body as approaching the laterally outside of the vehicle body, the reverse rotation shaft serving as a rotation shaft of the reverse pedal arm; a base portion attached to the floor and supporting the forward pedal arm, the reverse pedal arm, the forward rotation shaft, and the reverse rotation shaft; a coupling link configured to rotate in a first direction when receiving an operating force that rotates the forward pedal in a direction away from the operator, and configured to rotate in a second direction opposite to the first direction when receiving an operating force that rotates the reverse pedal in the direction away from the operator, wherein, when the forward pedal is rotated in the direction away from the operator, the operating force that rotates the forward pedal in the direction away from the operator is transmitted to the reverse pedal through the coupling link so that the reverse pedal rotates toward the operator, and wherein, when the reverse pedal is rotated in the direction away from the operator, the operating force that rotates the reverse pedal in the direction away from the operator is transmitted to the forward pedal through the coupling link so that the forward pedal rotates toward the operator; and a biasing member that biases the coupling link in the second direction when the coupling link rotates in the first direction, and that biases the coupling link in the first direction when the coupling link rotates in the second direction; and a transmission device configured to perform gear shift in accordance with an operating force applied to each of the forward pedal and the reverse pedal.
