Claims (1)
ストンにおいて、上記ピストン冠には触火面の反
対側に設けた中央穴から外周側へ放射状に複数個
のＴ字状断面の溝を形成し、同溝にボルトの頭部
を挿入し同ボルトと上記ピストン本体側のナツト
とにより上記ピストン冠と上記ピストン本体とを
結合したことを特徴とするピストン。 In a piston formed by combining a piston crown and a piston body, the piston crown has a plurality of T-shaped cross-section grooves radially formed from a central hole provided on the opposite side of the contact surface to the outer circumferential side. A piston characterized in that the head of a bolt is inserted into the groove, and the piston crown and the piston body are connected by the bolt and a nut on the piston body side.
