Liquid spray nozzle and liquid spray device

A liquid spray nozzle comprising:

• a tube in which a flow path through which liquid flows is formed;
• a nozzle member formed with at least one nozzle aperture, wherein the at least one nozzle aperture is configured to:
• spray the liquid in a continuous flow;
• and
• change the continuous flow into droplets;
• a first member that is provided with a flowing path configured to enable flow of the liquid, that is arranged between the tube and the nozzle member, and that has one end inserted into the flow path of the tube;
• a metal rigid member that presses and fixes the nozzle member against the first member;
• a second member that is fixed to the tube by pressing the tube from an outer side of the tube in a state where the one end of the first member is inserted into the flow path, wherein
• the second member is in a state where a portion of the second member bites into the tube at a position where the second member faces the first member via the tube,
• the first member has indentations and protrusions at the position where the second member faces the first member via the tube, and
• a portion of the tube bites into the first member in a state where the tube is partially entered into recess sections of the indentations and protrusions;
• and
• a spray tip end section spaced apart from the at least one nozzle aperture by a first distance in a spray direction of the liquid, wherein
• the first distance is longer than a droplet formation distance,
• the droplet formation distance is from the at least one nozzle aperture until the continuous flow is changed into the droplets, and
• an inner diameter of a hole of the spray tip end section is larger than an inner diameter of the metal rigid member.
