ABSTRACT:
In a writing device, an engaging portion having an annular protrusion and an annular depression is formed on the outer surface of the head end portion of a writing device body. Also, an engaging portion having an annular protrusion and an annular depression is formed on the outer surface of the tail end portion of the writing device body. A plurality of engaging protrusions are formed on the inner surface of a cap arranged at a predetermined spacing in the circumferential direction of the cap. When the cap is attached to the writing device body, the engaging protrusions move over the head end side annular protrusion and then engage with the head end side annular depression. When the cap is attached to the tail end of the writing device body, the engaging protrusions of the cap move over the tail end side annular protrusion and then engage with the tail end side annular depression. As a result of the engagement, the cap is less likely to unintentionally come off the writing device body. Also, a click occurs upon engagement, whereby the user can make sure that the cap has properly engaged with the writing device body.
