PROBLEM : To improve the precision of position of a fastener hole and a seating face for mounting a counterweight provided at a counterweight supporting member when the counterweight is mounted to the counterweight supporting member through a fastener bolt. SOLUTION : A counterweight supporting member (16) is comprised of a supporting plate (17) erected and fixed at the rear end of a revolving frame (9) and a supporting member (18) attached to the supporting plate (17) that is fixed to the revolving frame (9), and a cylindrical bolt fastening boss (21) is provided on the supporting member (18) in a manner of rotational position adjustable to the supporting plate (17) and in which a fastener hole (21a) is formed at an eccentric position.

    Cette invention vise à améliorer la précision de position d'un trou de fixation et d'une face d'assise pour le montage d'un contrepoids disposé sur un élément de support de contrepoids lorsque le contrepoids est monté sur l'élément de support de contrepoids au moyen d'un boulon de fixation. Plus précisément, l'invention concerne un élément de support de contrepoids (16), comprenant une plaque de support (17) dressée et fixée sur l'extrémité arrière d'un châssis tournant (9) et un élément de support (18) fixé à la plaque de support (17) qui est fixée au châssis tournant (9), et un bossage de fixation de boulon cylindrique (21) est formé sur l'élément de support (18) de sorte qu'une position de rotation soit ajustable à la plaque de support (17) et dans lequel un trou de fixation (21a) est formé dans une position excentrique.
