A nozzle fixed to the sprayer body extends outward through the notched portion of the trigger, and has a pair of axially extending stoppers integrally formed on the outer surface of the nozzle. The trigger can be rotatably connected to the sprayer body with ease due to the paired lugs being snap-fitted to the engagement grooves of the sprayer body and the upper end portions of the lateral walls of the trigger are prevented from being thrown inward by the stoppers of the nozzle and in consequence coming off the sprayer body. | |
