Abstract
A liquid discharge head includes a first housing, a sealing member, and a second housing. The first housing includes a nozzle from which a liquid is dischargeable and a liquid chamber communicating with the nozzle. The sealing member openably closes the nozzle. The second housing includes a moving member and a container. The moving member moves a portion of the sealing member between a first position at which the portion of the sealing member contacts the nozzle to close the nozzle and a second position at which the portion of the sealing member is separated from the nozzle to open the nozzle. The container stores and holds the moving member in the container. The sealing member is sandwiched between the first housing and the second housing to partition the liquid chamber and the container.
