Abstract: An energy storage apparatus includes an energy storage device, a first wiring electrically connected to the energy storage device, a harness plate holding the first wiring, and a first connector connected to the first wiring, the first connector being located at a central portion of the harness plate and capable of detachably attaching an external wiring.

Abstract: A device for manufacturing a laminated iron core includes a die and a punch configured to punch iron core pieces out of a thin-plate workpiece, a squeeze ring in which the iron core pieces are laminated, and a back-pressure device configured to apply back pressure to the laminated iron core pieces from a side opposite to the punch in a forward-backward direction of the punch. The back-pressure device includes a support body configured to move in the forward-backward direction, a biasing member configured to bias the laminated iron core pieces toward the punch, a drive device having an output shaft, and a conversion mechanism configured to convert rotary motion of the output shaft into linear motion of the support body in the forward-backward direction.

Abstract: A punch press includes a die, a punch, a support that supports the punch, a shifting member, and a rotating mechanism. The shifting member includes an opposing surface that opposes the punch. The shifting member is movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die. The shifting member includes a recess in the opposing surface. The rotating mechanism rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.

Abstract: A battery and an electrical apparatus accommodated in a battery pack body (1, 4) are effectively cooled. The battery pack body (1, 4) includes a battery region in which a battery module (2) is accommodated and an electrical apparatus region in which the electrical apparatus is accommodated. An air-suction portion (3) and an air-exhaust portion (37) are formed in the battery pack body (1, 4). Air which flows through the air-suction portion (36) is made to flow in the battery pack body (1, 4), thereby cooling the battery module (2) and the electrical apparatus and then, the air is made to flow out through the air-exhaust portion (37). The electrical apparatus region includes an electrical apparatus cover (27) which covers at least a portion of the electrical apparatus and which branches air which is sucked through the air-suction portion.
