A filter member is detachably mounted in a filter case formed with an inflow port through which washing water flows in and an outflow port through which the washing water flows out. The filter member includes a rib-shaped portion partitioning through holes adjacent to each other. At least one of the through holes is inclined from an inner peripheral surface of the filter member.

The case accommodates the washing treatment agent to be dispensed to a washing machine tank of the washing machine. The case includes a main body portion and a water supply portion. The main body portion includes a bottom portion that receives the washing treatment agent. The water supply portion supplies water to the main body portion. The bottom portion includes an upper surface including one end portion, the one end portion being positioned above another end portion in a first direction. The upper surface includes an inclined portion having a first gradient varying in the first direction, the first gradient indicating a ratio of a distance in a vertical direction to a distance in the first direction.

A surface-processed structure includes a plurality of blocks that are three-dimensional objects arranged on a target surface. The plurality of blocks are spaced apart from each other and are arranged side by side in a second direction. Each of the plurality of blocks includes a top face including a plurality of fine grooves. The plurality of fine grooves are spaced apart from each other, are arranged side by side in the second direction, and extend from upstream to downstream in a first direction. A width of each of the plurality of fine grooves in the second direction is less than a width of a block clearance in the second direction. Both end portions of the top face in the second direction are located above bottoms of the plurality of fine grooves in a cross section of the block extending along a plane perpendicular to the first direction.

A larger amount of light generated by a light source is emitted to the interior of an accommodation chamber. A lighting device provided on a side wall of an accommodation chamber of a refrigerator includes a light source that generates light, and a cover including a light incident portion on which the light generated by the light source is incident. The cover includes a light exit portion that includes a protrusion formed at a front surface facing the interior of a storage compartment, and causes light to exit to the interior of the storage compartment, and a light reflection diffusion portion that is formed on the back side of the light exit portion at a back surface facing the light source side, includes a plurality of recesses each having an inner peripheral surface, and directs light toward the protrusion.

A surface-processed structure includes a blocks arranged side by side in a first direction parallel to a target surface. The blocks are three-dimensional objects arranged on the target surface. Each of the blocks includes an inclined surface extending from upstream to downstream in the first direction with a distance from the target surface gradually increasing. The inclined surfaces of the blocks are arranged side by side on one line extending in the first direction. Each of the blocks includes a fine grooves provided on the inclined surface. The fine grooves are spaced apart from each other, are arranged side by side in a second direction orthogonal to the first direction, and extend from upstream to downstream in the first direction. The fine grooves extend at a constant depth from an upstream end portion to a downstream end portion of the inclined surface in the first direction.

A propeller fan includes a boss hub portion and a blade including a front edge portion, a rear edge portion, and an outer edge portion. The outer edge portion has a front outer edge portion, a rear outer edge portion, and a connection portion connecting the front outer edge portion and the rear outer edge portion to each other. In a plan view of the blade along a central axis, a maximum radius Rof the outer edge portion in a portion corresponding to the front outer edge portion and a maximum radius Rof the outer edge portion in a portion corresponding to the rear outer edge portion satisfy a condition of R&#x3e;R. With such a construction, a propeller fan which generates wind less in pressure fluctuation and is capable of sending comfortable wind and achieving lowering in noise is provided.

A propeller fan includes a boss hub portion and a blade including a front edge portion, a rear edge portion, and an outer edge portion. The outer edge portion has a front outer edge portion, a rear outer edge portion, and a connection portion connecting the front outer edge portion and the rear outer edge portion to each other. In a plan view of the blade along a central axis, a maximum radius R1of the outer edge portion in a portion corresponding to the front outer edge portion and a maximum radius R2of the outer edge portion in a portion corresponding to the rear outer edge portion satisfy a condition of R1&#x3e;R2. With such a construction, a propeller fan which generates wind less in pressure fluctuation and is capable of sending comfortable wind and achieving lowering in noise is provided.
