<P>PROBLEM TO BE SOLVED: To provide an easy-to-use knock type holder which has a small number of parts, and can be easily assembled. <P>SOLUTION: The knock type holder includes: an outer cylinder 10; an inner cylinder 20 which is inserted in the outer cylinder 10 so as to be movable in the axial direction, and holds a rod-like object C therein; and a spring 50 interposed between the outer cylinder 10 and the inner cylinder 20 to energize the inner cylinder 20 toward the rear end of the outer cylinder 10. By pushing the inner cylinder 20 against energization of the spring 50, the inner cylinder 20 and the rod-like object C are moved forward in the direction of the leading end of the outer cylinder 10. At the leading end portion of the inner cylinder 20, a plurality of locking pieces 26 for holding the rod-like object C and having expandable elastic force are provided while protruding in the leading end direction. On the inner peripheral surface at the leading end side of the outer cylinder 10, a protrusion part 14 for reducing the diameter of the leading ends of the locking pieces 26 of the inner cylinder 20 is formed, and also, on the side closer to the leading end side from the protrusion part 14, an expansion part 15 capable of housing the leading ends of the locking pieces 26 expanded when the inner cylinder 20 is pressed is formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
