PROBLEM TO BE SOLVED: To provide a reservoir capable of suppressing the deformation of a cap or injection part caused by the pressing force of a rib for holding a clamp flange. SOLUTION: A reservoir has an elastically deformable seal member 15 wherein an outer peripheral part 16 is pressed and held between a cap 9 and an injection part 2 when the injection part 2 is closed by the cap 9 and an annular clamp flange holding rib 20 is provided to the outer peripheral part 16. The clamp flange holding rib 20 is reduced in the rigidity in the inside direction of a radius direction to be easily deformed in the inside direction of the radius direction. |
