Abstract

A writing implement () wherein the outer circumferential surface of a crown outer cylindrical section () fits into the inner circumferential surface of a case () and the inner circumferential surface of a crown inner cylindrical section () fits into the outer circumferential surface of an attachment body (). In addition, an annular space () is formed in the crown (), between the inner circumferential surface of the crown outer cylindrical section () and the outer circumferential surface of the crown inner cylindrical section (). Air will flow through the annular space () even if, for example, the cap () becomes stuck in the bronchial tubes of an infant as a result of being accidentally swallowed by the infant. Suffocation accidents can, therefore, be reliably prevented.
