Abstract
A rotary manual controller for use with a game machine has a steering wheel manually operable by the game player to rotate a shaft in one direction or the other between a neutral position and a manipulated position, for entering information about a game player's rotary control action to develop a game played on the game machine. The rotary manual controller includes a biasing mechanism for biasing the shaft to return to the neutral position, and a restricting mechanism for restricting angular movement of the shaft. The biasing mechanism has a cam of a partly elliptical, elongate rectangular shape concentrically mounted on the shaft, a pair of abutment members extending transversely across the shaft and held in slidable contact with respective cam surfaces of the cam, and a helical spring for biasing the abutment members into slidable contact with respective cam surfaces of the cam.
