`
`Listing of Claims:
`
`1.
`
`(Currently Amended) An adapter structure for a ventilating fan, comprising:
`
`an oval metal adapter and an oval metal shutter provided in the oval metal
`
`adapter and cooperating with a shape of the oval metal adapter, wherein a symmetry
`
`axis of a longitudinal cross-section of the oval metal shutter in a horizontal direction is a
`
`major axis, and a symmetry axis in a vertical direction is a minor axis, the shutter is
`
`configured to be rotatable through a rotating shaft in the oval metal adapter, wherein:
`
`a curve point is defined between a projection point of a center line of the rotating
`
`shaft on the minor axis and a tail of the shutter, and a curve portion of the shutter is
`
`formed by curving the shutter from the curve point to an inner surface side of the shutter
`
`along the minor axis, ‘
`
`
`Wand a strai ht iine ortion is
`
`formed from a head of the avai meta! shutter to the
`
`

`ionditudinai cross~section of the oval metal shutter in the verticai direction and wherein the
`
`head and the taii are positioned at opposite ends of the oval metal shutter in the direction of
`
`the minor axis,
`
`wherein the curve portion of the shutter is formed smoothly from the curve point to
`
`the tail, and
`
`wherein when the shutter is opened, air flows from the air inlet of the oval metal
`
`adapter to the shutter.
`
`2.
`
`(Previously Presented) The adapter structure according to claim 1, wherein:
`
`the curve point is located on an upstream side where a distance is one third from the
`
`rotating shaft to the tail.
`
`3.
`
`(Previously Presented) The adapter structure according to claim 1, wherein:
`
`a rib is formed on the minor axis of the shutter, and a rib also is formed on a
`
`projection of the center line of the rotating shaft on the shutter.
`
`4.
`
`(Previously Presented) The adapter structure according to claim 2, wherein:
`
`a rib is formed on the minor axis of the shutter, and a rib also is formed on a

`
`projection of the center line of the rotating shaft on the shutter.
`
`5.
`
`(Previously Presented) The adapter structure according to claim 1, wherein:
`
`the rotating shaft is integrally formed on two inner sides of the metal adapter, and
`
`the shutter is formed by resin of a plate body, two clamp parts are provided for clamping
`
`the rotating shaft and erected from left and right edges of the plate body to an outside
`
`surface.
`
`6.
`
`(Previously Presented) The adapter structure according to claim 2, wherein:
`
`the rotating shaft is integrally formed on two inner sides of the metal adapter, and
`
`the shutter is formed by resin of a plate body, two clamp parts are provided for clamping
`
`the rotating shaft and erected from left and right edges of the plate body to an outside
`
`surface.
