  SOXS (Son of X-shooter) is a wide band, medium resolution spectrograph for
the ESO NTT with a first light expected in 2021. The instrument will be
composed by five semi-independent subsystems: a pre-slit Common Path, an
Acquisition Camera, a Calibration Box, the NIR spectrograph, and the UV-VIS
spectrograph. In this paper, we present the mechanical design of the
subsystems, the kinematic mounts developed to simplify the final integration
procedure and the maintenance. The concept of the CP and NIR optomechanical
mounts developed for a simple pre-alignment procedure and for the thermal
compensation of reflective and refractive elements will be shown.
