PROBLEM TO BE SOLVED: To provide a refill out-in mechanism of a writing appliance freed from unevenness in a protrusion length from the opening of the chip of the shaft cylinder of a pen body part. SOLUTION: In the refill out-in mechanism of the writing appliance formed that a rotor 30 making contact with the rear end of a refill 20 elastically projected against the tail end side is moved forward along the longitudinal groove of a cam cylinder 40 with a rotation force exerted on the rotor, and when the rotor is moved out from a cam cylinder, the rotor is slightly rotated in a rotation direction, and the tip of the protrusion part of the cam cylinder sliding along the slope of a front cam tooth 32 of the rotor is locked at the lock part of the rotor and writing is practicable, a notch part 35 is formed in the corner part of the lock part 33 of the rotor. |
