By pushing against the pressure, the writing shaft 3 is pushed out from the tip of the writing shaft 3 and the tip 6 of the outer cylinder 2, and in this pushed-out state, the writing shaft 3 is inserted into the writing shaft 3 or the notch portion 4.
The clip 1 is held by the locking protrusion 8 of the locking piece 7 having spring properties, and the tip of the clip 1 is inserted into the through hole 9 provided in the portion of the outer cylinder 2 facing the tip side of the clip 1. The writing shaft 3 is released by pushing in the inner protrusion and bending the locking piece 7 inward, and the locking piece 7 is released by the spring force of the retraction spring 5.
In a writing instrument in which the writing shaft 3 can be retracted until the locking protrusion 8 locks with the rear end 9a of the through hole 9, the clip 1 has first and second clips 1a, 1
b, which integrates the proximal end of the first clip 1a and the proximal end of the second clip 1b, and
The fitting hole 11 on the side of the protrusion on the inner surface of the tip of the clip 1a and the second
It has a double structure in which the tip inner surface protrusion 13b of the clip 1b is fitted, and the tip inner surface protrusion 13a of the first clip 1a communicates with the tip inner surface protrusion fitting hole 11, and the locking protrusion of the locking piece 7 is connected to the tip inner surface protrusion 13a of the first clip 1a. A writing instrument provided with an engagement hole 14 into which a portion 8 engages.

Claims

[Claims for Utility Model Registration] A writing shaft 3 is inserted into an outer cylinder 2 having a clip 1 on the rear end side, a notch portion 4 is fitted to the rear end of this writing shaft 3, and the notch portion 4 is Retract spring 5
By pushing against the pressure, the writing shaft 3 is pushed out from the tip of the writing shaft 3 and the tip 6 of the outer cylinder 2, and in this pushed-out state, the writing shaft 3 is inserted into the writing shaft 3 or the notch portion 4.
The clip 1 is held using the locking protrusion 8 of the locking piece 7 which has spring properties, and the tip of the clip 1 is inserted into the through hole 9 provided in the portion of the outer tube 2 facing the tip side of the clip 1. By pushing in the inner protrusion and bending the locking piece 7 inward, the writing shaft 3 is released, and the locking piece 7 is released by the spring force of the retraction spring 5.
In a writing instrument in which the writing shaft 3 can be retracted until the locking protrusion 8 locks into the rear end 9a of the through hole 9, the clip 1 has first and second clips 1a, 1
b, and second clips are provided in the proximal end side fitting portion 10 and the tip inner protrusion side fitting hole 11 of the first clip 1a, respectively.
Base end 12b and tip inner protrusion 13 of clip 1b
It has a double structure in which the clips b are fitted together, and the first clip 1a has a distal inner protrusion 13a, which communicates with the distal inner protrusion fitting hole 11 and engages with the distal protrusion 8 of the above-mentioned locking piece 7. A writing instrument provided with a matching hole 14.
