PROBLEM TO BE SOLVED: To provide a fluid feeding device with which a fluid connection is surely performed between a start chamber and a feed chamber and working is facilitated. SOLUTION: Concerning the fluid feeding device provided with a plunger 3 equipped with an operating part 10 movable in a bore 9 communicated with a start chamber 13 of a fluid D of remote operation in axial direction and communicated with a chamber 12 to which a fluid P pressurized to the side direction is fed, at least one part around the operating part 10 of the plunger has a much smaller radius in one corner area and when moving the plunger from a standstill position, a conduit through a gap formed from the small radius part 24 and the bore 9, which are communicated even when an orifice 23 of an internal conduit 22 is closed by a partition wall, is formed inside the plunger.
