Abstract
A foot massager includes a casing, an L-shaped mount having a horizontal wall fastened to the bottom of the casing and a vertical wall upstanding from the bottom of the casing, a motor horizontally mounted on the L-shaped mount, a foot rest suspended above the casing, an eccentric wheel driven by the motor through the mandrel of a speed reducing gear to oscillate the foot rest through an oscillating element via two links vertically disposed in parallel, each link having a top end pivoted to the vertical wall of the L-shaped mount and a bottom end pivoted to the oscillating element. The oscillating element has a top end connected to the foot rest, an elongated guide groove vertically disposed in the middle between the links and the eccentric wheel has a transmission shaft perpendicularly inserted into the elongated guide groove and turned to move back and forth along the elongated guide groove, causing the foot rest to oscillate.
