PURPOSE:To reduce thermal distortion and relieve wrong joining due to the difference between the thermal expansion coefficients by shrinking a link having a high polymer compound material and a metallic material connected thereto at the connection part or in the proximity thereof. CONSTITUTION:A reinforcing section 38 made of compound material in a link 14 connecting joints is connected to a york 28 made of aluminum at a fitting position 36 with the diameter of this part being small. For this reason, the terminal distortion of this part can be decreased with the decrease in the diameter, and as a result, wrong joining due to the difference between the thermal coefficients of the reinforcing section 38 and aluminum york 28 can be relieved. |
