A chuck key holder for a power tool, such as an electric or pneumatic drill or the like, comprises an elastic member mounted on a part of the power tool such as the handle. The elastic member has an aperture therein adapted to receive a part of the chuck key, the aperture being of such size as securely to retain the chuck key frictionally, and to permit ready removable thereof for use, and easy replacement following use. The end of the aperture into which the chuck key part enters advantageously is defined by a chamfered surface which serves to facilitate entry of the inserted part. The holder is permanent in nature, enables the user to return the chuck key to a definite place following each use, thereby assuring that the key will be available conveniently for the next use.
