An electronic device stores and holds a battery as a drive power source and has a configuration in which the battery can be attached/detached to/from the electronic device. In the electronic device, the battery lid in the electronic device includes a lid plate having a rib, and a lock plate configured to be movable to a first position and a second position with respect to the lid plate, and when the lock plate moves from the first position (non-lock position) to the second position (lock position) with respect to the lid plate, the battery is locked by the battery lock portion and stored and held in a predetermined battery hold position of the battery storage portion, and the battery lid is suppressed from being pressed by the stored and held battery.

With a cover structure of the present invention, a cover body includes a cover portion that is large enough to cover a terminal portion and a shaft portion whose one end is connected to the cover portion and whose cross section is oval, a casing includes a bearing portion in which the shaft portion is fitted loosely, and the bearing portion has a inner diameter larger than a shaft diameter of a major diameter portion of the shaft portion and includes an opening portion that is larger than a shaft diameter of a minor diameter portion of the shaft portion and smaller than the shaft diameter of the major diameter portion. With this configuration, the cover body can be smoothly shifted from an opened state to a closed state and a portion to be covered can be covered properly. Furthermore, the assembling workability of the cover structure can be improved.

A separator for sealed cells is provided which attains a high degree of intimate contact with electrode plates, enables the cell to have reduced internal resistance, is less apt to suffer a fatigue phenomenon even upon repetitions of charge/discharge, and improves the life of the cell. Fine rubber particles are adhered to the surface of fibers of a non-woven fabric constituting the separator so that the fine rubber particles are present among the fibers. These fine rubber particles function as elastic bodies to absorb relative positional changes of the fibers and improve the compressive repulsion of the separator.
