A multiblade fan includes an impeller including a rotating plate and blades and further includes a fan casing having a circumferential wall and a first end face disposed adjacent to distal ends of the blades. The first end face has an inlet. The multiblade fan further includes a duct and a flow regulating block disposed on an inner surface of the first end face. The flow regulating block regulates a flow of the air. The duct includes a diffuser plate. The circumferential wall includes a tongue that is connected to the diffuser plate. The first end face has a bell mouth provided at the inlet. The flow regulating block is spaced from the circumferential wall and extends along the bell mouth in the rotation direction such that the flow regulating block is located in a range of 120 degrees from a reference position on a line connecting the rotary shaft to a tip of the tongue.

A centrifugal fan includes: an impeller driven by a drive motor to rotate; a scroll casing including an inlet-port face having an opening and a wall portion having positions at which distances from an axis line that is a rotation center of the impeller differ from each other, and changing an air flow in a centrifugal direction generated by rotation of the impeller into an air flow in one direction; an air admitting portion including a bell mouth portion having a large-diameter side end placed on an inlet-air-flow upstream side of the inlet-port face; and a protruding portion extending from the air admitting portion in a direction orthogonal to the axis line, which is the rotation center of the impeller, and in a direction away from the rotation center and surrounding part of the bell mouth portion.

A hand dryer includes an air-stream generating device including a device air inlet, an inner housing that accommodates therein the air-stream generating device and has an inner air inlet formed in an intake surface thereof, and an outer housing that accommodates therein the inner housing and the air-stream generating device and has an outer air inlet formed therein. An intake air passage that connects the outer air inlet and the device air inlet to each other is formed inside the outer housing to include the intake surface and an opposing surface as a portion of a wall surface thereof, and a projection is provided on the opposing surface to project from a region that is opposed to the inner air inlet towards the intake surface. The projection has a first surface facing an upstream side in the intake air passage.

A multiblade centrifugal blower includes a centrifugal fan including a hub rotated by a motor, and plural curved rectangular blades arranged at predetermined intervals in a circumferential direction of the hub forming a cylindrical basket with an opening on a front side of the hub, and a scroll casing including an air inlet and an air outlet, and houses the centrifugal fan inside to face the air inlet. A length from a rear end to an front end of an outer edge of the blade is shorter than a length from a rear end to an front end of an inner edge of the blade, and a bell mouth is configured such that distance between a tip part of the inner edge of the blade and an inner wall of the scroll casing is the minimum at an inner tip part P of the bell mouth of the air inlet.

A seat back has a seat back frame, a plane spring structure, and a headrest provided at the upper end of a seat back frame. The plane spring structure has left and right side wires, and horizontal wires extending in the horizontal direction. Connection wires are provided between the seat back frame and plane spring structure. First end portions and second end portions of the connection wires function as detachable portions. At least one of these detachable portions is detached from the seat back frame or plane spring structure by the load applied to the seat back, when a vehicle is bumped from behind.

A plurality of curved rectangular blades are arranged in a circumferential direction on a periphery of a disc, forming a pipe-like basket shape with an opening on a front side of the disc. Rotation of the disc draws in air from the opening and draws out the air in a centrifugal direction through a space between the blades. The blades are formed of a thick plate part close to the disc and a thin plate part that is thinner than the thick plate part and farther than the thick plate part from the disc. A bulge serving as a boundary between the thick plate part and the thin plate part is formed on a negative pressure surface of the blades, which is of curved convex shape.

A seat apparatus comprises a backrest portion which can be tilted, a hook mounted on the upper portion which is a tilting end, a sitting portion which can raise on a fulcrum, which is a front edge, and an engaged portion which can engage a book mounted on a rear. When the sitting portion is raised, the rear of the sitting portion is turned toward the backrest portion side. When the backrest portion is tilted forward, the hook is engaged with the engaged portion, the backrest portion and the sitting portion are fixed to each other, and then it is in a double folded state. The hook is arranged at a position where a tether strap for mounting an auxiliary seat on the backrest portion is hung. The hook is integrally formed with a guide of the tether strap.
