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.
