PROBLEM TO BE SOLVED: To previously avoid the risk of outbreak of an operation failure in a releasing mechanism due to adhesion of mud.SOLUTION: The speed maintenance releasing structure for a working vehicle includes: a speed maintaining device 13 which maintains a vehicle body in a constant velocity forward traveling state; and a mechanical releasing mechanism 26 which releases the maintenance of the vehicle body in the constant velocity forward traveling state by a speed maintaining device 13 when a pair of right and left brake pedals 18 and 17 are operated at the same time. The right and left pedals 18 and 17 are structured into a suspension type, which respectively swings forward and backward around a support shaft 21 arranged in the right and left direction higher than a boarding surface 4B of a boarding and operating part 4. The releasing mechanism 26 is disposed near the support 21, and is connected to the right and left brake pedals 18 and 17, and is also connected to the speed maintaining device 13 through a mechanical connecting mechanism 48. The mechanical connecting mechanism 48 is passed upward and downward from a part between the support shaft 21 and a front wall 4A of the boarding and operating part 4, which is stood just in front of the support shaft 21, along the front wall 4A, is passed under the boarding surface 4B, and is connected to the speed maintaining device 13.
