Abstract: To provide a battery cooling apparatus capable of obtaining a sufficient amount of blown air even when a cooling fan has a predetermined size and achieving cost reduction and size and weight reduction. A rotor shaft of a motor extends in the shaft direction to the outside of a motor case, a plurality of impellers is assembled to the rotor shaft, as many cooling blowers as a plurality of vehicle battery units are assembled integrally to the motor, and discharge ports of the cooling blowers are disposed so as to face the openings of housing boxes housing the vehicle battery units.

Abstract: A driving device includes an endless metal belt having a strip shape, rotational members, and a polisher. The rotational members bear the metal belt to allow the metal belt to run circularly. The polisher is disposed so as to come in contact with the widthwise opposite end edges of the metal belt to thereby polish the opposite end edges of the metal belt in running.

Abstract: A curl correcting device includes a first roller, a second roller and a supporting unit. The supporting unit includes a first conveyance path and a second conveyance path. The first roller is rotated about a first rotary shaft and elastically deformable. The second roller is rotated about a second rotary shaft and elastically deforms the first roller by being pressed against the first roller, thereby forming a curved nip portion between the first and second rollers. The supporting unit is rotatable about a third rotary shaft and rotatably supports the first and second rollers. The first conveyance path communicates with the sheet conveyance path by the supporting unit being arranged at a first position about the third rotary shaft. The second conveyance path communicates with the sheet conveyance path by the supporting unit being arranged at a second position about the third rotary shaft.
