Abstract
A lie-down massager includes a base frame having an elongated top panel, through which an elongated top opening is formed centrally and lengthwise, a rider, a guide member movably engaged between the base frame and the rider so as to enable the rider to make a horizontally reciprocal movement, massage bumps that move vertically and horizontally along the top opening, and a lifter that holds the massage bumps and adjusts the height of the massage bumps. The lifter includes a top member, a bottom member, a screw shaft and a motor. The screw shaft engages with a nut block and the nut block is connected with the top member by two links so that rotation of the screw shaft is converted into horizontal movement of the nut block, and the horizontal movement of the nut block is converted into vertical movement of the top member.
