内面チャック機構。A tapered bushing is integrally provided on the shaft inserted through the support body, and a chuck member consisting of a plurality of plate springs is arranged around the tapered bushing at predetermined angular intervals, and the proximal end of this chuck member is It is fixed to a support, a sliding member is provided at the free end so as to come into contact with the tapered surface of the tapered bushing, and a stopper is provided around the chuck member to define a mounting position of the chucked object. However, when the object to be chucked is attached to the outside of the chuck member and the large diameter part of the tapered bushing is pushed into the sliding member side, the outer diameter of the free end side is smaller than the outer diameter of the proximal end of the chuck member. The inner surface is configured such that when the tapered bushing is retracted and the small diameter portion is positioned on the sliding member side, the diameter on the free end side of the chuck member becomes as small as the diameter on the proximal end side. Chuck mechanism.
