Document Type and Number:
Japanese Patent JP2018146025
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress damage on an adhesion layer between a base part of a blade body and a connection member.SOLUTION: A fastening structure includes: a blade body having a leading edge and a trailing edge, and on a base end side of which a base part 14 is formed; a connection member 30 having an outer wall part 40 covering at least a part of an outer peripheral surface 17 (outside surface) of the base part 14; and an adhesion layer 60 provided between the outer peripheral surface 17 of the base part 14 and an inner peripheral surface 33 (inside surface) of an outer wall part 40, and contacting with the outer peripheral surface 17 of the base part and the inner peripheral surface 33 of the outer wall part 40. The adhesion layer 60 has uneven thickness according to an angle around a central axis, on any cross section orthogonal to a central axis of the base part 14, and a thickness at such an angle that a leading edge side and a trailing edge side around the central axis are projected on the cross section, is made smaller than average of thicknesses of the whole circumference around the central axis.SELECTED DRAWING: Figure 4
