To provide a trigger dispenser in which elastic deformation resistance of an arch spring part is enlarged in the second half of a drawing operation of a trigger, a spring force for putting back to a front at the time of self reset starting of a trigger can be strengthened, and thereby which enables to carry out self reset of the trigger certainly.
The trigger dispenser includes a pump device 3 which takes out liquid in a liquid container 2, a trigger 4 prepared in the pump device 3, and a spring 5 which carries out elastic deformation by drawing operation of the trigger 4, wherein the spring 5 includes: a pair of arch spring parts 50 which are curved convex upward, and arranged at right and left of the pump device 3; a fulcrum part 51 which is at an opposite side of a front end part 50a connected with the trigger 4, and is held by permitting the pump device 3 to rotate in a circumference of a horizontal axis; and extended spring parts 52 which are extended behind the arch spring parts 50, contact to the pump device 3 from middle of elastic deformation of the arch spring parts 50, and gives resistance to the elastic deformation of the arch spring parts 50.
