Patent ID: 8142091

Claim:
A writing implement comprising: a shaft tube formed in a cylindrical shape, a reduced-diameter portion which is formed at an end of the shaft tube and has an outside diameter smaller than that of a remaining part of the shaft tube, and a cylindrical grip member made of flexible elastic material fitted to the reduced-diameter portion from the end of the shaft tube; the shaft tube having a step so formed as to correspond to an end of the grip member, the step having a step surface opposing to the end of the grip member, the step surface being so formed as to be inclined with respect to a vertical plane perpendicular to a central axis of the shaft tube, the grip member having a step-facing surface opposing to the step surface, the step-facing surface being so formed as to be inclined with respect to the vertical plane perpendicular to the central axis of the shaft tube, and an inclination angle formed between the step-facing surface of the grip member and the vertical plane being smaller than that formed between the step surface of the shaft tube and the vertical plane when the step-facing surface of the grip member and the step surface of the shaft tube are inclined in the same direction with respect to the vertical plane.
