Abstract: 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.

Abstract: A stationary exercise apparatus includes a framework, a curved shaft, two oil pressure cylinder sets, and two pedals. The curved shaft has two curved ends and a straight portion located between the two curved ends. The two curved ends are pivoted with the framework such that the two curved ends form a deflection angle of 180 degrees when the curved shaft is driven to turn radially. The two oil pressure cylinder sets are fastened between the framework and the curved ends of the curved shaft for providing the curved shaft with a damping effect. The two pedals are mounted on the straight portion of the curved shaft for driving the curved shaft to turn radially.

Abstract: A deck chair has a frame having a back frame, a seat frame, a leg frame, a front support frame, a rear support frame outside the back frame and two side stretchers. Two positioning members pivotally mount the back frame to the seat. Two armrest-adjusting members are respectively pivotally mounted at top ends of the front support frame and the rear support frame. When the positioning members are locked, the back frame and the seat frame can be pivoted about the positioning members with a changeless included angle.
