Claims

[Scope of utility model registration request]

A slit in the axial direction is provided on the side surface of the shaft cylinder from the rear end opening edge to a required distance forward position, and a window hole is provided at a required position in front of the slit, and a clip ball portion with a groove on the lower surface is opposed to the window hole. The plate is placed above the slit, and a locking part is provided near the rear end of the clip plate or on the clip mount, and a notch is provided at the rear of the refill, which is stored in the barrel with a spring biased backwards. A locking protrusion is provided on the knock body to engage with the window hole of the shaft tube while the tip writing portion of the re-feel protrudes from the shaft tip opening and to fit into the groove of the clip ball portion. An elastic piece part is provided at the rear end of the clip plate that protrudes rearward, and an elastic piece part that penetrates through the slit of the barrel and is located between the clip plate and the side surface of the barrel, and an upper surface of the tip thereof. When the tip writing part of the protruding re-feel is recessed into the barrel, it engages with the locking part provided on the clip plate or the clip mounting base, and is elastically displaced by pressing the elastic side surface and is engaged. A lock-type writing instrument characterized by being provided with a stopper consisting of a locking part that can eliminate the problem.
