Abstract: A concealed slide module is formed by installing an inner plate, at least one first ball plate, a middle plate, at least one second ball plate and an outer plate sequentially and installed between a bottom side of a drawer and a cupboard. The middle plate covers the exterior of the first ball plate and has an inner sidewall facing the inner plate and having a roof portion protruded horizontally outward from the top side of the middle plate, and a sliding section bent inwardly from a lower edge of the sidewall, and the sliding section is parallel to the platform, and a guide wheel is protruded from an outer sidewall at an end of the middle plate, and the middle plate slides with respect to the inner plate through the first ball plate.
