A piston and cylinder unit (1) includes a cylinder housing (2), a piston (7), a piston rod (18) and a securing element (20). The piston (7) includes an opening (13), at least one piston seal (11) and an inner thread (15) being located in the opening (13). The piston rod (18) has an axis (9) and includes a protrusion (21), an outer thread (23) and a second thread (27). The outer thread (23) is located on the protrusion (21). The second thread (27) is located at the piston rod (18). The piston (7) and the piston rod (18) are connected by the inner thread (15) and the outer thread (23). The securing element (20) is designed and arranged to substantially extend in the direction of the axis (9). The securing element (20) includes a thread (24), the securing element (20) and the piston rod (18) being connected by the thread (24) of the securing element (20) and the second thread (27) of the piston rod (18). The securing element (20) is designed and arranged to be active in an axial direction in a way to prevent rotational movement of the piston (7) in a loosening direction. The threads (15, 23) of the piston (7) and of the piston rod (18) are designed and arranged to be operated in a direction opposite to the threads (24, 27) of the securing element (20) and the piston rod (21). |
