Document Type and Number:
Japanese Patent JP6784512
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a top rod that has high torsion strength and is hard to cause plastic deformation while being a rod body on the basis of a solid rod-shaped core body.SOLUTION: A top rod is a solid rod-shaped body comprising a glass reinforcing fiber group and a matrix resin. An outer layer 1D provided to the outside of the solid rod-shaped body has an inside prepreg tape 13A for an outer layer being wound spirally with a narrow width and an outside prepreg tape 13B for the outer layer being wound spirally with the narrow width being wound so that carbon reinforced fibers of inside/outside prepreg tapes for those outer layers may intersect with each other in a radial direction view, and further, has a winding lead angle of the inside/outside prepreg tape to the axis line being set to 60°-89°in an enlarged diameter portion of a former edge side in the solid rod-shaped body.SELECTED DRAWING: Figure 6
