PROBLEM TO BE SOLVED: To provide a connecting structure of a handle shaft, which prevents an excessive rotational force from being transmitted to a driven portion even by a difference between specifications on the side of an input shaft, manufacturing tolerance, etc. SOLUTION: This connecting structure of the handle shaft comprises: the input shaft 23 which has a handle 13 fixed to one end 17, which has a circular hole 21 provided in a recessed manner in the other end surface, and which is rotatably supported on a door 11; a driven shaft 29, the one end 25 of which is fitted into the circular hole 21 so as to be supported on the door 11 in such a manner as to be rotatable relatively to the input shaft 23, and the other end 27 of which is connected to a driven portion 15; a cam plate 33 which is fixed to the input shaft 23, and which has a circumferential notched portion with a predetermined length; a stopper pin 35 which regulates the rotation of the cam plate 33 in the range of a predetermined angle of rotation; a regulating means for regulating the rotation of the driven shaft 29 in the range of the angle of rotation, smaller than the predetermined range of the angle of rotation; and a spring member 37 which is provided between the side of the input shaft and that of the driven shaft, which rotates the driven shaft 29 in a driven manner by the rotation of the input shaft 23, and which allows the rotation of the input shaft 23 beyond the range of the regulation of the rotation of the driven shaft 29 by elastic deformation.
