The door actuator (1) has a drive spring (3) for storing the closing- or opening energy for a door leaf, and a housing comprising two housing sections (21,22). The former housing section partially accommodates the drive spring. The former housing section is screwed into the latter housing section. A piston of a drive unit (4) of the door actuator is guided on the inner surface of the latter housing section. The former housing section is formed in a cup-shaped manner with a lateral surface (211) and a front surface (212). |
