1. A leaf spring, wherein the leaf spring is arranged between a sealing member having a locking groove and a mating sealing member having an insertion space into which the sealing member and the leaf spring are inserted, the leaf spring comprising:
a curved body section;
a locking protrusion protruding in one direction at an end of the body section to be inserted into the locking groove of the sealing member; and
a detachment-prevention protrusion protruding, at the end of the body section, in a direction opposite to the locking protrusion and configured to come into contact with one surface of the mating sealing member and prevent the locking protrusion from being detached from the locking groove when the body section is compressed by the sealing member and the mating sealing member,
wherein the curved body section has a curved central surface at an intermediate portion of the body section and a curved end surface toward the end of the curbed body section, the curved central surface and the curved end surface being curved in opposite directions to each other, the curved central surface being curved such that the curved central surface meets the one surface of the mating sealing member smoothly and the curved end surface being curved such that the curved end surface of the both section meets a surface of the sealing member smoothly.
