Abstract: A fan shroud and a blower device are provided. The fan shroud includes a shroud wall surface and a plurality of ventilation openings. The shroud wall surface extends around a fan along a radial direction orthogonal to a rotation axis. The plurality of ventilation openings are formed through the shroud wall surface in a thickness direction of the shroud wall surface to allow passing of wind generated by a fan motor. A width of a wall surface side opening on a downstream side of the wind in the ventilation opening is smaller than a width of a lateral wall side opening on an upstream side of the wind in the ventilation opening.

Abstract: Provided is a chip component manufacturing method which enables a plurality of chip pieces to be handled while being pasted to a sheet, and in which it is possible to apply at least a surface treatment to a plurality of chip pieces while being pasted to a sheet. This chip component manufacturing method comprises: a step for retaining a green sheet or the like on a carrier sheet; a step for cutting, together with a portion of the carrier sheet, the green sheet or the like retained on the carrier sheet; a step for removing, together with a portion of the carrier sheet, at least a dummy portion of the green sheet or the like that has been cut, so as to leave a plurality of chip pieces on the carrier sheet; and a step for applying at least a surface treatment to lateral surface portions of the plurality of chip pieces that have become exposed due to the removing while the plurality of chip pieces are being retained on the carrier sheet.

Abstract: A blower device includes a motor having an output shaft and a housing; a fan rotationally driven by the motor; and a shroud having a shroud body with a fan installation hole, and a motor mounting part for mounting the motor arranged inside the fan installation hole when viewed in an axial direction of the output shaft. The motor mounting part includes an inner cylinder surrounding a periphery of the motor from a radial outer side of the output shaft; an outer cylinder surrounding the inner cylinder from the radial outer side; and spokes connecting the inner and the outer cylinders. The inner cylinder includes a top wall covering the motor from above while the shroud is fixed. A back end edge of the top wall, which is located on a positive pressure side when the fan is rotated, is located closer to the positive pressure side than the housing.

Abstract: A cooling-fan-apparatus fan shroud includes: a cover wall that closes a space between a heat exchanger and a circumference of a fan; and a passing permitting frame part that is positioned between the fan and an attachment part to a vehicle at an outer side of the cover wall and that allows free passing of traveling air, wherein a reinforcement rib is provided at an opening of the passing permitting frame part, and at least part of the reinforcement rib is a deflection louver that guides the traveling air to a predetermined direction.

Abstract: A cooling fan includes a boss section (12) connected to a rotary drive source, a plurality of blades (13) protruding outward from the boss section in a radial direction, and a cylindrical ring member (14) configured to annularly connect the vicinities of end sections outside in the radial direction of the plurality of blades. The plurality of blades (13) protruding outward from the boss section (12) in the radial direction are connected by the cylindrical ring member (14) in the vicinity of the end section outside in the radial direction. An air inlet groove (16) is formed at an end section in an axial direction of an air suction side of the ring member (14). The air inlet groove (16) is disposed between front regions in the rotation direction of all of the blades (13) on the ring member (14) and front regions in the rotation direction of the blades (13) adjacent thereto.
