Abstract

PURPOSE: To dwindle the load applied onto liner fixing bolts by forming spots, where liners to be tightly fixed at the protrudent part of a runner come to get a hit with a fixative frame, over the tapered surface, etc.
CONSTITUTION: The angular extremity of L type liner 9 tightly fixed by a bolt 10 is made to be a tapered surface 9a over the underneath wall and the side wall of a protrudent part 3a of a runner. By these procedures, when the protrudent part 3a of the runner has come to get a hit with a fixative frame 5 due to deviation or vibration of a main shaft, the hit spots by the L type liner 9 with another L type liner 8 become the final extremity of the tapered surface 9a. In consequence, the load point of the impact load does not become the fulcrum of a bolt fixing side piece of the L type liner 9, any bending moment does not engender at this bolt fixing side piece, the load applied onto the bolt 10 is dwindled. Further, if the tapered surface 9a is made into a bent surface, the same effect will be given.
