A trigger type liquid sprayer comprises a mount cylinder (2) fitted onto a neck portion of a container body, a vertical cylinder (2a) provided upright on the mount cylinder (2), a jetting cylinder (3) projecting forward from an upper end of the vertical cylinder (2a), a cylinder (4) projecting forward from an intermediate portion of the vertical cylinder (2a), a plunger (6) slidably fitted in the cylinder (4) and biased forward, a trigger (5), a rear surface of an upper portion of which engages with a forward end of the plunger (6) and which is swingably mounted to a forward end of the jetting cylinder (3), a nozzle fitting cylinder (7) mounted to a forward end of the jetting cylinder (3), and a nozzle head (8) formed with nozzle holes (10) and rotatably mounted to an outer surface of the nozzle fitting cylinder (7). An arm (21) projects rearward from an outer surface of the nozzle head (8), a first engaging portion (23) is provided on an upper portion of the trigger (5), and a second engaging portion (26) is provided on a forward surface of a lower portion of the cylinder (4). When the trigger (5) is positioned at a foremost location and the nozzle head (8) is turned, a portion of the arm (21) detachably engages with the first engaging portion (23), and the other portion of the arm (21) detachably engages with the second engaging portion (26), whereby the plunger (6) will not move rearward even when a user attempts to pull the trigger (5).
