Intermediate casing for a gas-turbine engine

The housing has an outer ring (3), inner ring (1) and an intermediate ring (2), which are supported against each other via an inner strut (4. 1) and outer strut (5.1). An auxiliary device gear box (7) is connected with a radial shaft (6). Other outer struts (5.2- 5.5) are arranged between the outer ring and the intermediate ring in an angular interval at a periphery. A fastening work area (8) is fixed in region of the latter outer struts at an outer side of the outer ring via a pivot (9) and a spigot (10) that is molded at the work area and attached at the outer ring in a fixed manner.
