Abstract
A massaging device having a track comprising two rails. The rails comprise a first V-shaped raceway spaced apart from a second raceway. The device includes a carriage that causes a massaging unit comprising a pair of massaging to move back and forth along the rails. Coupled to the carriage are a pair of guide wheels having diamond-shaped cross-section, and engaging the first raceway. A biasing wheel if pivotally coupled to either side of the carriage and spring loaded in a direction away from the guide wheels as to engage the second raceway and maintain the carriage within the rail. The massaging unit comprises a pair of massaging members that are mounted to a rotable shaft in such a fashion as to perform a finger pressure-like massage or a tapping massage.
