<P>PROBLEM TO BE SOLVED: To provide a portable electric lamp with a structure capable of preventing gas generation or liquid leakage of cells and reducing the number of components, since a reverse-connection preventing structure is difficult to provide as a plurality of cells are arranged in one line, the reverse connection of the cells causes gas generation or liquid leakage, and when the plurality of cells are arrayed in a horizontal line, the reverse-connection preventing structure is easy to provide but the number of components increases so as to practically raise component cost and assembling cost. <P>SOLUTION: In a structure with a plurality of cells arranged in a horizontal line, as a means for reducing the number of components of a switching structure, a light-emitting part and a cell housing part are insertion-coupled in free rotation, and turning on position/turning off positions are provided in accordance with the rotational position as a switching function. Moreover, a center of a terminal of a pole for at least one cell among a plurality of them is arranged at a position away from a rotation center axis of the light-emitting part and the cell housing part, and a connection lead facing and conducting to a terminal of one of the poles of the cell is set at a position to be conducted or not conducted in accordance with rotation of the light-emitting part and the cell housing part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
