Trigger-type liquid sprayer

A trigger-type liquid sprayer comprising:

• a sprayer main body mounted on a container body configured to accommodate a liquid therein;
• and
• a nozzle member having a spray hole for spraying the liquid forward, the nozzle member being mounted on a front end portion of the sprayer main body,
• wherein the sprayer main body includes:
• a vertical supply tube extending in an upward/downward direction and configured to suck up the liquid in the container body;
• a trigger mechanism having a trigger portion disposed in front of the vertical supply tube to be movable rearward in a state in which the trigger portion is biased forward, the trigger mechanism being configured to cause the liquid to flow from an inside of the vertical supply tube toward the spray hole in response to rearward movement of the trigger portion;
• a reservoir cylinder into which the liquid that has passed through the inside of the vertical supply tube is supplied in response to rearward movement of the trigger portion;
• and
• a reservoir plunger disposed inside the reservoir cylinder to be movable in an axial direction along a center axis of the reservoir cylinder, and configured to move toward one side in the axial direction in response to supply of the liquid into the reservoir cylinder while being biased toward the other side in the axial direction,
• the reservoir cylinder is disposed above the vertical supply tube, intersects a center axis of the vertical supply tube, and protrudes rearward beyond the vertical supply tube, and
• a displacement curbing portion is provided between a rear cylinder portion of the reservoir cylinder protruding rearward beyond the vertical supply tube and the vertical supply tube, the displacement curbing portion being configured to curb displacement of the rear cylinder portion with respect to the vertical supply tube.
