ABSTRACT:
A clicking-type writing implement includes a writing element having a writing portion at its distal end, a spring for urging the writing element toward the end, and a clicking rod loosely fitted interlocked with the writing element so as to project from a barrel cylinder. Upon depression of the clicking rod, the engaging rib of a rotor in the barrel cylinder and the engaging bead in the inner cylinder engage with each other, so that the writing element projects and stays projected from a front portion of the barrel cylinder. This clicking-type writing implement also has a so-called double clicking mechanism and a safety mechanism. According to the double clicking mechanism, the clicking rod is projected upon depression and is retracted upon further depression. According to the safety mechanism, when the engaging bead and the engaging rib engage with each other, the projecting state of the writing portion of the writing element is maintained, and when the engaging bead is lifted, the writing element is retracted. No cam surfaces are formed on the inner surface of the barrel cylinder. In the inner cylinder, a cam is formed on the front edge of a cylindrical portion inserted and fixed in the barrel cylinder.
