Abstract:
Provided is a knock type writing instrument provided with a simple mechanism allowing a stable fretting operation or the like. A knock type writing instrument  1  is provided with: a shaft cylinder  2;  a refill  5  arranged inside the shaft cylinder  2;  a spring  6  biasing the refill  5  backward; an operation part  20  pressed forward against a biasing force of the spring  6  in a knocking operation; and a main rotor  30,  and is switchable between a writing state and a non-writing state with the knocking operation. The knock type writing instrument  1  is further provided with: a knock locking member  50  movable forward and backward inside the shaft cylinder  2  due to gravity; and a locking part  60  provided on a side of the shaft cylinder  2  and capable of being locked with the knock locking member  50.  When a front end of the shaft cylinder  2  is directed upward, the knock locking member  50  moves backward to be locked with the locking part  60  to prevent forward movement of the operation part  20.

Claim (Index 2):
The knock type writing instrument according to  claim 1 , wherein\n said knock type writing instrument is switched between the writing state and nonwriting state by said engaging member being engaged with or disengaged from an engaging part provided at said barrel side and further comprises a speed reducing rotor moving in a front-back direction together with said writing member and a first cam face making said speed reducing rotor rotate about a center axis in cooperation with said speed reducing rotor while said writing member is moving backward.
