A vehicle hydraulic clutch apparatus includes a clutch master cylinder that generates clutch working oil pressure in response to operation of a clutch pedal, and a concentric slave cylinder that engages and releases a friction clutch as the clutch working oil pressure generated by the clutch master cylinder is supplied thereto and discharged therefrom via an oil passageway. A flow restraint device (130, 200) that restrains flow of the working oil from a concentric slave cylinder (66) side to a clutch master cylinder (62) side which occurs according to operation of the clutch pedal (60) is provided in the concentric slave cylinder (66).
