)項記載の建設機械。[Claims for Utility Model Registration] (1) In a construction machine consisting of a work machine main body, a front extending forward from the work machine main body, and a work implement pin-coupled to the front end side via a connecting pin. The construction machine is characterized in that a half-shaped eccentric spacer is removably provided on the connecting pin so that the mounting position of the working tool can be eccentric with respect to the center line of the front. (2) The eccentric spacer is formed of plate materials having a thickness corresponding to the amount of eccentricity so as to be able to abut each other,
Utility model registration claim (1) consisting of two spacer bodies having semicircular pin holes on the abutting surfaces and a fixture for integrally fixing each spacer body.
Construction machinery listed in ).
