Abstract
A valve includes: a casing; a valve body that is operable inside the casing; a biasing member that biases the valve body; and a retainer that holds the biasing member, wherein the retainer is provided with a flange portion caulked and fixed to the casing by a caulking end provided at one axial end of the casing, and wherein an elastic member is sandwiched between the flange portion and the casing to be axially elastically deformable.
Claims11
A valve, comprising:
- a casing;
- a valve body that is operable inside the casing;
- a biasing member that biases the valve body;
- and
- a retainer that holds the biasing member,
- wherein the retainer is provided with a flange portion fixed to the casing by a bending piece provided at one axial end of the casing, and
- wherein an elastic member is sandwiched between the flange portion and the casing to be axially elastically deformable, and
- wherein the bending piece is formed by bending inward-radially, toward the flange portion, a protruding portion which protrudes in an axial direction from an axial end surface of the casing brought into contact with the biasing member.
A method of assembling a valve including a casing, a valve body operable inside the casing, a biasing member that biases the valve body, and a retainer that holds the biasing member,
- wherein the retainer is provided with a flange portion fixed to the casing by a bending piece provided at one axial end of the casing, and
- the method comprises a step of
- forming the bending piece by bending inward-radially, toward the flange portion, a protruding portion which protrudes in an axial direction from an axial end surface of the casing brought into contact with the biasing member while an elastic member disposed between the flange portion and the casing is axially compressed.
