A massaging machine includes a massaging device and a steering mechanism for operating the massaging device. The steering mechanism has a shaft on which a drive gear and a driven seat are mounted. The drive gear is driven by a motor to actuate the massaging device to operate. The driven seat is provided with a unidirectional bearing by which the driven seat is mounted on the shaft. The unidirectional bearing is intended to disable the massaging device to engage in a reciprocating motion at the time when the drive gear is driven to turn in a reverse direction.
