<p>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 linear protrusion 21b is formed on one of joint surfaces 21a, 21a of the vane proximal end portion 21 to the pair of divided pieces 34, 34. A groove 35b engaged with the linear protrusion 21b formed in the vane proximal end portion 21 is formed on one of respective joint surfaces 35a, 35a of the pair of divided pieces 34, 34 of the coupling support member 33. 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 pair of divided pieces 34, 34 of 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.</p> |
