Abstract

PURPOSE: To shorten the tool exchanging time by installing the movable key to be engaged with the key groove of a tool and urging the movable key by a spring and driving-out the movable key by means of the rotational driving-force when the tool is key-engaged with the main shaft in revolution.
CONSTITUTION: The movable key 37 which is engaged in detachable form with the key groove of the tool T held by the tool holding parts 13a and 13b is pivotally supported by a pin 38 at both ends areas of a tool exchanging arm 13 by freely projecting to and retreating from the holding part. The movable key 37 is urged in the direction projecting to the holding part by the spring 39 inserted between the tool exchanging arm 13 and the movable key 37. Even if the tool T held in the holding parts 13a and 13b is forced to revolve, revolution of the tool T can be suppressed by retreating the movable key 37 with an overwhelming force by a spring 39 and when the tool T is compulsorily driven by the key engagement with the main shaft 11 in revolution, the movable key 37 is driven-out by said driving force, and frictional revolution of the tool T can be permitted.
