速操作構造。 An arm 9 that swings integrally with the speed regulating pedal 7, which can be stepped forward and backward, is connected to the pedal 7, and the central part of the pedal swing range is set as a neutral position N.
Continuously variable speed adjustment for vehicle speed adjustment, such that the forward speed increases as the pedal 7 is depressed further forward than the neutral position N, and the reverse speed increases as the pedal 7 is depressed further backward than the neutral position N. A first contact portion 13a that defines a swing range of the arm 9 to one side by contacting the arm 9, which is a speed change operation structure for a working vehicle in which the device 3 and the arm 9 are linked; A second contact portion 13b that defines the range of swing of the arm 9 to the other side by contact with the arm 9 is provided on one restraint tool 13, and a second contact portion 13b is provided for attaching the restraint tool 13 to the vehicle body. A speed change operation structure for a work vehicle in which a bolt hole 15 for a bolt 14 is an elongated hole extending in the swinging direction of the arm for adjusting a swing range defining position.
