Beschreibung
Zusammenfassung:	A coupling support member 33 including a pair of divided pieces 34, 34 is placed in a coupling part between a vane proximal end portion 21 of a guide vane 20 and an attachment flange 31f, and the pair of divided pieces 34, 34 are joined to the vane proximal end portion 21 from both the sides in the vane thickness direction. A groove 35b is formed in one end portion joint surface 35a of the coupling support member 33, a linear protrusion 35c is formed on the other end portion joint surface 35a, the vane proximal end portion 21 is formed into a concavo-convex shape, a linear protrusion 21b that is engaged with the groove 35b which is formed in the end portion joint surface 35a is formed on a joint surface 21a to the one end portion joint surface 35a, a groove 21c that is engaged with the linear protrusion 35c formed on the end portion joint surface 35a is formed in the joint surface 21a to the other end portion joint surface 35a. The vane proximal end portion 21 is held between the pair of divided pieces 34, 34 of the coupling support member 33, by the fastening force that is applied to the coupling support member 33 from both the sides in the vane thickness direction. It is possible to obtain a high structural strength while contributing to a reduction in weight of a jet engine.
