Document Type and Number:
Japanese Patent JP5044186
Kind Code:
B2
Abstract:
A chuck is provided for use with a manual or powered driver. The chuck has a body with angularly disposed passageways. A plurality of jaws is slidably positioned within the angularly disposed passageways. A nut is rotatably mounted about the body member and has threads defined on an inner circumference that engage jaw threads. A sleeve is in driving rotational engagement with the nut so that when the sleeve is rotated with respect to the body, the jaws are moved within the passageways. A stopping mechanism that rotates with the sleeve is provided with at least one elastic stop pawl. When the stopping mechanism rotates in a first direction that causes the gripping jaws to move to the rear of the body to a predetermined position, the stop pawl blocks the lateral surface of the gripping jaws and prevents further rotational movement of the nut.
