PROBLEM TO BE SOLVED: To detect an oscillation angle of an oscillation member with high accuracy in an oscillation angle detecting device for the oscillation member jointed with the oscillation member so that one edge portion of an operation shaft disposed on an opposite side to a drive shaft in regard to a fulcrum of the oscillation member may swing, and jointed with the operation shaft inserted in a guide hole provided at a fixed support member so as to be slid so that a detecting rod of a sensor may detect the oscillation angle of the oscillation member corresponding to an axial position of the operation shaft. SOLUTION: The operation shaft 26A can oscillate around an axis orthogonal to a flat surface including a straight line connecting a joint portion to the oscillation member 20 of the drive shaft, the fulcrum of the oscillation member 20, and the joint portion to the oscillation member 20 of the operation shaft 26A. A detecting rod 96A which is removably supported by the support member 34, inserted in the guide hole 75A, and has an axial line coaxial with the oscillation axial line of the operation shaft 26A is jointed with the operation shaft 26A enabling rotation around the axial line.
