A power storage module includes a plurality of power storage devices and a bus bar electrically connecting the plurality of power storage devices. Each power storage device has a housing and a pair of output terminals disposed on a first surface of the housing. The bus bar has the plurality of terminal connections connected to the output terminals of each power storage device, and a linking part connecting the plurality of terminal connections. Each terminal connection part has a first part connected to each output terminal and a second part continuous from the first part and extending along a second surface spreading in a direction intersecting the first surface of the housing. Each linking part has a third part that connects the second parts of the adjacent terminal connections to each other.

A battery pack includes: a plurality of battery modules disposed adjacent to each other in a first direction inside a pack case, each of the plurality of battery modules including a plurality of battery cells disposed side by side in a second direction, the second direction being orthogonal to the first direction; and a side-frame disposed between the battery modules disposed adjacent to each other in the first direction inside the pack case. The side-frame includes two side-walls and a joint. The two side-walls elastically press side-surfaces, in the first direction, of the battery modules disposed adjacent to each other. The side-frame has a long-length shape with a U-shaped cross section. In a state where the side-frame is removed from the battery modules disposed adjacent to each other, a distance between the two side-walls of the side-frame becomes larger as the two side-walls go away toward opposite the joint.

Battery pack and production method therefor

An electric vacuum cleaner is equipped with a dust collection unit () that can be detachably installed in the air passage en route from a suction unit to an electric fan of the cleaner. The dust collection unit () comprises a dust collecting case () for accumulating dust sucked in, a lid member () that can be opened to discharge the accumulated dust; and a lock mechanism (clamp lever) () for locking the lid membertightly closed. The dust collection unit () is further provided with a hand grip (), arranged to face said user, thereby facilitating a user to hold the dust collection unit when discharging dust from the bottom of the dust collecting case. Further, a hinge () is arranged at a position which is adjacent to said bottom () of said dust collecting case () facing the user holding the hand grip. Furthermore, a lock mechanism () is arranged near the periphery of the lid member () and at a position opposite to the hinge.

Dust collection unit for electric vacuum cleaner and upright electric vacuum cleaner

An electric vacuum cleaner is equipped with a dust collection unit () that can be detachably installed in the air passage en route from a suction unit to an electric fan of the cleaner. The dust collection unit () comprises a dust collecting case () for accumulating dust sucked in, a lid member () that can be opened to discharge the accumulated dust; and a lock mechanism (clamp lever) () for locking the lid membertightly closed. The electric vacuum cleaner is further provided with a lid opening mechanism (lid opening stick () for forcibly opening the lid member () in cooperation with the lock mechanism locking the lid member. Even when the sealing pressure of the packing is high or when the accumulated dust does not weigh on the lid member because the dust is compacted on the inner wall of the dust collecting case, the lid member can be opened without difficulty to discharge the dust, without opening it by hand. Thus, the user can avoid handling unsanitary dust.
