ABSTRACT:
a pen adapted to be pressurized and capable of being manufactured inexpensively, with which ink can be smoothly supplied and an excessive pressurization within an ink accommodating tube and the leakage of ink can be prevented, as well as a pen that can be easily used in a state that a pen tip is directed upwardly. The pen comprises a pressurizing pump mechanism10which pressurizes an inside of ink accommodating tube3and includes a pressurizing chamber14communicating with the inside of the ink accommodating tube, an elastic spherical body16disposed to be pushed into the pressurizing chamber, a compression spring17that urges the spherical body in a direction to be released from within the pressurizing chamber, and a pressing stem18that moves the spherical body against the urging force of the compression spring into the pressurizing chamber in an airtight state.
