Claims

[Scope of utility model registration request]

A transmission shaft is provided that is rotatable around the axis that transmits power from the engine to the rotary shaft of a rotary working machine, and a cylindrical transmission shaft case that covers the transmission shaft is provided, and the lower end of the transmission shaft case is connected to the rotary shaft of the rotary work machine. In a transmission device for a rotary working machine, the rotary shaft is rotated in a plane perpendicular to the transmission shaft by connecting rotary cases holding shafts and rotating the transmission shaft case around the axis, A spline portion is formed on the outer periphery of the upper end of the transmission shaft case, and a lock body that is movable between a position where the spline portion engages and a position where the engagement is released is attached to the case that holds the upper portion of the transmission shaft case. Characteristic transmission device for rotary work machines.
