Abstract
The first case has an outer surface extending portion at which the end edge side of the first case extends toward the second case side at an outer surface side of the main body case, and also has an inner surface extending portion at which the end edge side of the first case extends along an inner surface of the second case, and the outer surface extending portion and the inner surface extending portion of the first case sandwich the step-shaped projection of the second case in a state where the first case and the second case are joined, and upper end edges of the holder side walls support a lower end edge of the inner surface extending portion by contacting.
Claims16
A power supply device connectable to electric equipment for supplying power, comprising:
- a main body case divided into a first case and a second case, and having an extending shape in one direction;
- a secondary battery incorporated in the main body case;
- and
- a battery holder for holding the secondary battery,
- wherein
- the second case has a box shape having a bottom portion, and a pair of case side walls in a longitudinal direction,
- the battery holder has a pair of holder side walls to hold both sides of the secondary battery,
- the holder side walls are formed so as to extend upward along at least a part of the case side walls from the bottom portion of the second case in a state where the battery holder is stored in the second case, and the holder side walls are lower than the case side walls in height,
- end edges where side walls of the first case and the side walls of the second case are joined, have step shapes in a vertical sectional view perpendicular to the longitudinal direction,
- the second case has a step-shaped projection at an end edge side of the second case, the projection extending toward the first case side at an inner surface side of the main body case,
- the first case has an outer surface extending portion at an end edge side of the first case, the outer surface extending portion extending toward the second case side at an outer surface side of the main body case, and an inner surface extending portion at the end edge side of the first case, the inner surface extending portion extending along an inner surface of the second case,
- the outer surface extending portion and the inner surface extending portion of the first case sandwich the step-shaped projection of the second case in a state where the first case and the second case are joined,
- wherein upper end edges of the holder side walls are in contact with and support a lower end edge of the inner surface extending portion.
