A shaving apparatus has a housing ( ), a shaving head ( ) and a hair-collecting chamber ( ) for collecting hair cuttings, the shaving head comprising a holder ( ) which is connected to the housing by means of a hinge construction ( ). The holder comprises an external cutting member ( ) and an internal cutting member ( ). For driving the internal cutting member a drive member ( ) of a drive unit ( ) can be coupled to the internal cutting member ( ). For cleaning the hair-collecting chamber ( ) the chamber is opened by pivoting the holder ( ) and after the cleaning process the holder is pivoted back onto the housing. During opening and closing of the hair-collecting chamber the drive member ( ) and the internal cutting member ( ) are coupled and uncoupled. In order to improve coupling and uncoupling the hinge construction is such that in a first stage of the movement of the holder the holder is moved substantially in a longitudinal direction ( ) of the drive member ( ).
