<P>PROBLEM TO BE SOLVED: To provide a leaf spring which can secure a necessary displacement without necessarily needing thinning of a material or impairing uniform distribution of resilient force, and to provide a molten-salt battery using the leaf spring. <P>SOLUTION: The molten-salt battery includes: a molten-salt battery body having a laminated structure, which is housed in a battery container; a presser which abuts on one end surface in the lamination direction of the body; and a spring which biases the presser so as to compress the molten-salt battery body in the lamination direction while holding it between the inner surface of the battery container and the presser. As the spring, the leaf spring 13 using a metal plate as the material is used. The leaf spring 13 has a ring-like or polygonal frame shape in a planar view, and includes bellows-like irregularity repeatedly formed in the circumferential direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
