Abstract

PURPOSE:To improve the breaking strength of a cantilever with high specific modulus of elasticity by coating the external circumference of a cantilever made of boron or boride in a pipe shape with resin. CONSTITUTION:The external circumference of a cantilever body 9 formed in a pipe shape by using boron or boride of TiB2, etc., is coated with resin 10. In this case, the external circumference of the cantilever body 9 is either coated with epoxy resin, or covered with tubular resin such as nylon and polypropylene or heat-shrinkable tubular resin. Consequently, an impact applied to the cantilever body 9 is absorbed by the resin 10 to make the cantilever body 9 having high specific modulus of elasticity hard to break because of improved brittleness.
