Claims

[Scope of utility model registration request]

A hollow king pin case is attached to the outer end of a hollow front axle disposed on the lower front surface of the vehicle in a direction perpendicular to the traveling direction of the vehicle, and a cylindrical king pin is protruded from the lower surface of the king pin case. , a power transmission device in which a gear case that pivotally supports a front wheel shaft to which a front wheel is attached is rotatably and slidably fitted onto the king pin, and an upper shaft and a lower shaft are configured to be extendable and retractable within the cylindrical king pin. The shaft is inserted through the shaft, and the upper shaft is supported within the kingpin case and power is transmitted to the axle within the front axle within the kingpin case, while the lower shaft is supported within the gear case and power is transmitted to the front axle within the gear case. A front axle device for an agricultural working machine, which transmits power and is provided with a spring for resisting compression between an upper shaft and a lower shaft of the power transmission shaft or between a king pin case and a gear case.
