To provide a crusher for glass moldings which can easily and more minutely crush the crushed materials of glass moldings with no complication or enlargement of a device.

In the crusher, the crushing part 24 of the glass moldings 11 is installed in a box body 22, and an introducing supporting part 23 successively introducing the glass moldings 11 to the crushing part 24 and a discharge part 25 discharging the crushed materials to the outside of the box body 22. The crushing part is provided with a rotary shaft 47, a hammer 57 protruded from the rotary shaft 47 in a radiation direction and slidable circumferentially, and a breaker 45 arranged at a place apart from a predetermined distance from the rotary shaft 47. The breaker 45 is installed at the upper part counter to the rotating direction of the rotary shaft 47, and has a shear surface 45b imparting shearing force between it and the hammer 57 and a crushing surface 45c installed at the side part of the hammer 47, so that the impacting force is imparted toward the crushing surface 45c to the glass moldings 11 by the hammer 57.
