PROBLEM TO BE SOLVED: To perform reliable central position holding operation by a simple holding mechanism. SOLUTION: This shift operation device is provided with a rotation member 2 rotated in linkage with movement of a shift lever 1, and a holding mechanism to hold the rotation member 2 in the central position of a rotation range, The holding mechanism is provided at one end with a roller 70 and at other end with a twist coil spring 7 fixed at a frame and a cam surface 26 formed at the rotation member 2 and with which the roller 70 at one end of the twist coil spring 7 is brought into slide contact. The twist coil spring 7 is used as a spring member and by applying a spring force on the cam surface 26 of the rotation member 2 by using a spring member, holding in a central position is executed.
