Patent number: 6174618Abstract: The invention provides a battery holder consisting of one plate-like support member and another support member. A plurality of battery holes of a predetermined depth into which sealed portions of a positive or negative side of sealed-type batteries that are clamped at one side by the support member are to be respectively fitted are formed in one face of the support member, so that one row of the battery holes is a row for positive terminals and another row of the battery holes is a row for negative terminals. A terminal hole is formed in a bottom face of each of the battery holes. A groove is formed between adjacent paired positive-terminal and negative-terminal holes among the terminal holes disposed in the bottom faces of the battery holes of the rows. The paired positive-terminal and negative-terminal holes are communicated with each other through the groove. Vent holes are opened at appropriate places among the battery holes.Type: GrantFiled: September 30, 1998Date of Patent: January 16, 2001Assignee: Japan Storage Battery Co., Ltd.Inventors: Koichi Nishiyama, Yoshinori Tanaka, Takehito Matsubara
