Abstract:
A coupling support member including a pair of divided pieces is placed between an end portion of a guide vane and an attachment flange, and the pair of divided pieces is joined to the vane end portion from both sides in the vane thickness direction. A linear protrusion is formed on one of joint surfaces of the vane end portion. A groove engaged with the linear protrusion is formed in one of respective joint surfaces of the pair of divided pieces. The vane end portion is fastened between the pair of divided pieces. It is possible to obtain a high structural strength while contributing to a reduction in weight of a jet engine.
