A massaging machine includes a motor-driven hollow shaft including two ends each defining a slot. A shaft which includes a right-hand thread and a left-hand thread is insertable through the hollow shaft. A first distance-adjusting member includes a T-flange on an external surface and includes a right-hand thread on an internal surface for engaging with the right-hand thread on the shaft. A second distance-adjusting member includes a T-flange on an external surface and includes a left-hand thread on an internal surface for engaging with the left-hand thread on the shaft. Two cylinders each include an inclined face at an end and defines a T-slot in an internal surface for engaging with one of the T-flanges. Two sleeves are each insertable in one of the cylinders and are each mountable on one of the ends of the hollow shaft so that the T-flange of each sleeve is slidably received in one of the slots of the hollow shaft. Two wheels are each mounted by means of bearing on one of the sleeves. A plurality of elastic bosses are attached on each of the wheels.
