The endoscope has a head (3), which is connected by a bendable end piece (2) with an endoscope shank (1) to a tubular construction unit. Between the endoscope shank and the bendable end piece a rotation element (4) for rotating the bendable end piece is inserted around the longitudinal axis of the endoscope shank. The rotation element (4) has a coaxial drive, and a reduction gear (10). The bendable end piece has a bending mechanism, which makes bending possible of the end piece and only into a reduced number of directions such as two dimensions.
