Abstract

PURPOSE:To improve the brittleness of a cantilever with high specific modulus of elasticity by inserting a light metallic pipe of aluminum, etc., into the pipelike cantilever made of boron or boride. CONSTITUTION:A pipe 10 made of light metal such as aluminum, magnesium and titanium is inserted into the circular part of a cantilever body 9 formed by shaping boron in a pipe. The pipe 10 is adhered favorably with epoxy resin, etc. Thus, the cantilever body 9 is reinforced by the light metallic pipe 10 to make the cantilever body 9 hard to break.
