A fluid pressure-feeding device includes: a balloon pump of a bag shape that is elastically expandable, contractible and deformable, and defines a pump chamber inside; and a flow path unit that includes at least a portion of a flow path communicating with the pump chamber. The balloon pump and the flow path unit are integrally arranged. The flow path includes a supply path that supplies a fluid to the pump chamber, and a discharge path that discharges the fluid from the pump chamber. The discharge path has a greater pressure loss than the supply path.

Provided is a cylindrical vibration isolation device for vehicle auxiliary machine having a novel structure, in which a main-body rubber elastic body having a low spring property suitable for a vehicle auxiliary machine can be employed. A cylindrical vibration isolation devicefor vehicle auxiliary machine is provided with an inner shaft memberand an outer bracketattached to one of a vehicle auxiliary machineand a vehicle-body-side support member. A cylindrical partexternally fitted over the inner shaft memberis provided to the outer bracket. The inner shaft memberand the cylindrical partare connected by a main-body rubber elastic body. The inner shaft memberis provided with a stopper protrusionthat protrudes to the outer peripheral side at a position protruding in an axial direction from the main-body rubber elastic body. The outer bracketis provided with a first stopper parthaving an axis-perpendicular contact surfaceopposing the stopper protrusionin an axis-perpendicular direction, and a second stopper parthaving an axial-direction contact surfaceopposing the stopper protrusionin the axial direction, at positions protruding in the axial direction from the main-body rubber elastic body
