Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a nozzle that discharges a liquid;
• a pressure chamber that communicates with the nozzle, accommodates the liquid, and generates a pressure for discharging the liquid from the nozzle;
• a flow channel which is connected to the pressure chamber and through which the liquid flows;
• a flow channel wall portion that constitutes a part of a wall surface of the flow channel, is displaced to change a cross-sectional area of a part of the flow channel, and changes a flow channel resistance of the flow channel;
• and
• an actuator that displaces the flow channel wall portion,
• wherein an displacement amplifying mechanism for increasing a displacement amount of the flow channel wall portion more than a displacement amount of the actuator is provided between the actuator and the flow channel wall portion,
• wherein the displacement amplifying mechanism includes
• an elastic material that is connected to the actuator and is elastically deformed by displacement of the actuator, and
• an accommodation chamber that is partitioned from the flow channel by the flow channel wall portion and accommodates the elastic material on the flow channel wall portion, and
• wherein a first portion of the elastic material receiving a pressure from the actuator, a second portion of the flow channel wall portion being bent and deformed between the flow channel and the accommodation chamber by receiving a pressure from the elastic material, an area of the second portion being less than an area of the first portion.
