Abstract: A motor cooling fan unit comprises a tubular cover capable of surrounding a motor and a fan provided to blow air toward the interior of the cover. The motor cooling fan unit is configured to cause air blown from the fan to pass through a flow path between the motor and the cover. The cover comprises an exhaust part provided at a downstream area of the flow path. The exhaust part comprises: an open part for making the flow path communicate with the outside; and an exhaust adjusting member provided for the open part and movable between a shield position at which the exhaust adjusting member covers the open part and an open position at which the exhaust adjusting member opens the open part. The amount of movement of the exhaust adjusting member is adjusted to allow adjustment of the amount of the air in the flow path to be exhausted through the open part and a direction of the exhaust, or adjustment of the amount of the air to be exhausted or a direction of the exhaust.

Abstract: Provided is a manufacturing device for a rotor core and a manufacturing method for a rotor core in which it is possible to suitably fit a columnar core rod into a center hole of a laminated iron core, when fitting and installing the laminated iron core into a fitting recess of a first mold. A device for manufacturing a rotor core includes: a first mold; a second mold that engages with the first mold and clamps and seals the laminated iron core together with the first mold; a resin injection unit that is provided to the second mold and injects a resin material in the magnet insertion hole by using a molding machine; and a guide plate that has a through hole into which the core rod is inserted and is mounted at one end of the laminated iron core in such a manner that the through hole is in communication with the center hole of the laminated iron core, in which the guide plate has an opening diameter of the through hole on one surface side of one end side of the laminated iron core that is substantially the same as an opening diameter of the center hole, and an opening diameter of the through hole on the other side on the side of the first mold is larger than an opening diameter on the one surface side.
