FIELD: machine engineering.
SUBSTANCE: bolted joint of parts comprises bolts which are installed by smooth sections in the holes of the first part with clearance enclosed by the holes of the second part. A washer is installed under the head of each bolt, which hole is made with eccentricity relative to its outer diameter for rotation relative to the bolt under the action of groove walls during movement of the first part within the limits of specified clearance defining direction of the movement. In this case, in order to provide better contact of the washer with the first part after final fixation, the corresponding flat surface of the washer is made corrugated.
EFFECT: providing unloading of bolts from transverse forces acting in given direction when changing mutual position of parts to be fixed.
