PURPOSE:To prevent local generation of portions of much resin by cutting end face of reinforced fiber flux of a core previously and enabling extrustion of resin. CONSTITUTION:An end face 1C of a reinforced fiber flux 1 of a core unit 12 is cut slantly at an angle of theta of 45 deg. or less desirably to the longitudinal direction without cutting at a right angle to the longitudinal direction of a leaf spring. Thus, as the end face 1c of fiber flux of the core unit 12 is cut slantly, tip portions are easily smashed when end portions are pressued in squeezing and excessive resin is easily extruded. Then, generation of portions where mush resin is remained locally can be prevented. |
