Abstract
A lie-down massager includes a base frame having a top panel, a rider provided below the top panel of the base frame, a guide member movably engaged between the base frame and the rider to enable the rider to make a horizontally reciprocal movement relative to the base frame, massage bumps that move vertically along an elongated top opening of the elongated top panel of the base frame, and a lifter that holds the massage bumps and adjusts the height of the massage bumps. The lifter includes a top plate, a bottom plate, a fluid operated cylinder fixed to the bottom plate, and a spring fixed between the top plate and the bottom plate. The fluid operated cylinder has a cylinder shaft that is moved by pressurized fluid overcoming the force of the spring, and a guide shaft and a guide bearing that have a square cross section.
