Abstract

In a retaining structure for a tooth (2) that makes use of a retaining pin assembly (4) that is inserted into through-holes (2a and 3a) through which the tooth (2) and an adapter (3) pass, a metal retaining pin (11) with no uneven surface is used as a member constituting the retaining pin assembly (4) for fixing the tooth (2) so that it will not fall off under a force exerted in the direction of moving the tooth (2) away from the adapter (3). Members made all of metal are used as bushings (14a and 14b), bolts (12a and 12b), and washers (13a and 13b) for keeping this retaining pin (11) from falling out of the through-holes (2a and 3a).
