A tilt-swivel head (1) for optical apparatus (19) has a housing (2), a base (4) for mounting the housing, actuators for swiveling about a first, vertical swivel shaft (AS-AS) and for tilting about a second, horizontal tilt shaft (AN-AN) connecting the housing to the apparatus (19). The extruded section (3) is mounted with its lengthwise axis horizontal, has vertical end surfaces and one horizontal portion and at least one vertical portion which, together with the remainder of the extruded section, form a single tubular hollow body. Also, the vertical swivel shaft (AS-AS) passes through the horizontal portion of the extruded section, and the horizontal tilt shaft (AN-AN) passes through the vertical portion of the extruded section. Lastly, two covers (22) are fastened on the two vertical end surfaces of the extruded section (3).
