Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an enclosed lead battery which has need for changing a switching valve pressure of a safety valve during the manufacturing process as a switching valve pressure proper at degassing of battery bath is different from a switching valve pressure proper as the product in a safety valve of the enclosed lead battery. SOLUTION: During degassing of the battery bath the safety valve 7 is held on valve pressing plate 8 having spring elasticity and after degassing of the battery bath, a central cover 3 is in contact with an upper cover 9 for limiting deformation of the valve pressing plate 8.
