Abstract: The embodiments relate to a spring assembly for returning a piston by urging the piston slidably arranged in a case in a predetermined direction. The spring assembly includes: an annular member; and plural spring members fixed to the annular member and arranged to urge the piston against the case. The annular member includes plural notch portions disposed on one of an inner periphery and an outer periphery of the annular member between the adjacent spring members, and plural standing wall portions disposed on the other one of the inner periphery and the outer periphery of the annular member opposite to the notch portions between the adjacent spring members. Each of the standing wall portions has a linear shape when viewed in a direction along a central axis passing through a center of the annular member.
