A massaging device includes a propeller shaft, at least one first swinging member mounted on the propeller shaft, and at least one second swinging member mounted on the propeller shaft by a male deflection block, a female deflection block and an adjusting rod. Thus, when the rotation direction of the propeller shaft is changed, the push block of the adjusting rod is slidable in the adjusting groove of the male deflection block to produce a time lag of the swinging actions between the second swinging member and the first swinging member, so that the second swinging member and the first swinging member are operated in the same swinging direction or in two different swinging directions so as to produce different swinging actions, thereby providing different massaging effects to the user.
