Guide vane segment for a turbomachine

A guide vane segment for a turbomachine, comprising:

• at least one guide vane element, which includes at least one flange formed in a radial extension direction of the guide vane element and at least one positioning member projecting from the flange in the radial extension direction, and
• at least one seal carrier, which is positioned at the flange and is aligned relative to the guide vane element by way of the positioning member, wherein the flange has a supporting surface on which the seal carrier is supported;
• wherein a partial surface of the positioning member is adjacent to the flange at a transition from the flange to the positioning member, and respective surface normal lines of the supporting surface and of the partial surface enclose between them an angle that is different from a zero angle,
• wherein the at least one seal carrier has at least one encircling radial groove, with which the positioning member is engaged in the arrangement of the seal carrier at the flange,
• wherein the positioning member has at least two positioning mandrels arranged fork-like to one another extending directly downward from the supporting surface, the partial surface of the position member defines at least a portion of a face of the respective mandrels, and these mandrels engaging in the encircling radial groove in the arrangement of the seal carrier at the flange,
• wherein a gap is defined between the seal carrier and the face of the respective mandrels along an entire length of the mandrel, and
• wherein the partial surface is at least a partially curved surface.
