The present invention suppresses an increase in pressure of internally contained lubricating oil and reduces leakage of the lubricating oil. This actuator is provided with: an accumulator which has a gas compartment at the top filled with gas, and in which a lubricating oil is contained under the gas compartment; a housing internally provided with the accumulator; a shaft of which one end side is contained in the housing and another end side is disposed outside the housing, and which is moveable in an axial direction; and an oil seal disposed between a first opening portion which is formed in the accumulator and through which the shaft penetrates, and the shaft. The housing has formed therein a pipe channel providing communication between a space on the side opposite to the inner side of the accumulator with respect to the oil seal and the gas compartment of the accumulator.
