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 1):
A knock type writing instrument comprising a barrel, a writing member arranged inside said barrel, an elastic member biasing said writing member backward, an operating part which is pushed forward against a biasing force of said elastic member at the time of a knock operation, and an engaging member and performing a knock operation enabling a writing state and a nonwriting state to be switched,\n which knock type writing instrument further comprises a knock lock member able to move inside said barrel in a front-back direction by gravity and a locking part provided at said barrel side and able to lock with said knock lock member, when a front end of said barrel is turned upward, said knock lock member moving backward to lock with said locking part whereby movement of said operating part forward is obstructed.
