Abstract: A liquid leakage detection device of the present invention includes a sensor unit and a determination unit. The sensor unit is configured to detect liquid between seals of a plurality of seals that are arranged aligned in an axial direction on an inner circumference of a shaft supporting member, which is an inner circumference of the shaft supporting member into which a shaft is movably inserted, to seal an outer circumference of the shaft. The determination unit is configured to determine whether or not liquid leaks, through detection of liquid by the sensor unit.
