A liquid cartridge mountable on a liquid droplet ejection device, includes a liquid chamber configured to store a liquid therein, and a pump unit configured to generate a pressure for the liquid stored in the liquid chamber to be supplied to the liquid droplet ejection device. The pump unit includes a cylinder; a piston slidably mounted in the cylinder and configured to define a pressure chamber with the cylinder; a force transfer member coupled to the piston and including an engagement portion and a support portion; and a support member configured to contact the support portion to support the force transfer member to be movable. The engagement portion is configured to engage a drive member of the liquid droplet ejection device and to receive a drive force from the drive member to displace the piston.
