PURPOSE:To seal a writing liquid in a writing device hermetically and reduce a load acting upon the tip of a writing shaft when the shaft is fed out by installing a cylinder and a blocking element so that they attract each other magnetically and energizing the blocking element to a position where the cylinder attracts the cylinder, utilizing the elastic restoration force of a connecting member. CONSTITUTION:If a refill 14 is squeezed out from a tip direction by knocking operation, a blocking element 22 is pushed by the tip of the refill 14 and becomes upright, thus allowing the refill 14 to become ready for use. As the connecting part 242 of a connecting member 24 becomes deformed significantly, a load rests on a writing element 143 due to an elastic restoration force when the refill 14 is projected. However, the load is minimum and therefore the writing element 143 is protected against damage. After use, the refill 14 is returned to a storage position again by knocking operation. The blocking element 22 is returned to a position where it gets close to the tip surface of a cylinder 18 by the elastic restoration force of the connecting member 24, and is magnetically attracted by the cylinder 18. Then the blocking element 22 is closely fixed to the tip surface and its interior is sealed hermetically. The vapor supplied to an airtight chamber in the cylinder 18 from an ink occlusion element 145 is prevented from becoming dry. |
