Abstract

First and second upstream fins and first and second downstream fins are arranged in the air passage of air-conditioning air to pivot. The first upstream fin includes an upstream body with a cutout extending upstream from the downstream edge. A transmission shaft, which extends along upstream fin shafts, is arranged in the cutout. The first downstream fin includes a downstream body with a slidable operation knob. The operation knob includes a fork that is rotationally supported with a support shaft. The fork includes a pair of transmission pieces, which extends upstream from the operation knob and sandwiches the transmission shaft. The transmission shaft includes a pair of stoppers, which is located at positions that are spaced from each other in the extending direction of the transmission shaft and that sandwich the transmission pieces. The stoppers are caused to contact the transmission pieces by operation of the operation knob.

First claim

The invention claimed is:

1. An air-conditioning register comprising:
a downstream fin including a downstream body and a downstream fin shaft, which are located in an extending direction crossing a flow direction of air-conditioning air, wherein the downstream fin is supported to pivot about the downstream fin shaft;
an upstream fin including
an upstream body and an upstream fin shaft, wherein each of the upstream body and the upstream fin shaft extends in a direction that crosses both the flow direction and the extending direction of the downstream fin shaft,
a cutout formed in the upstream body to extend upstream from a downstream edge of the upstream body, and
a transmission shaft that is located in the cutout to extend along the upstream fin shaft, wherein the upstream fin is located upstream of the downstream fin and supported to pivot about the upstream fin shaft;

an operation knob arranged to slide relative to the downstream body in the extending direction of the downstream body;
a fork including a pair of transmission pieces that extend upstream from the operation knob and that sandwich the transmission shaft, wherein the fork is supported with a support shaft to be rotational relative to the operation knob; and
a pair of stoppers arranged on the transmission shaft, wherein the stoppers are spaced from each other in the extending direction of the transmission shaft and located at positions that sandwich the transmission pieces, the stoppers are caused to contact the transmission pieces by operation of the operation knob, and the pair of stoppers limits a movable range of the transmission pieces to a distance between the pair of stoppers, wherein
each transmission piece includes a facing edge that contacts the corresponding stopper,
each stopper includes a contact surface that contacts the facing edge of the corresponding transmission piece,
a portion of the transmission shaft between the stoppers includes a columnar body shaft,
the contact surface of each stopper is formed by a portion of the stopper that borders the body shaft,
the contact surface of each stopper is formed to have a truncated conical shape so that a diameter increases as a distance from the body shaft increases,
each stopper is connected to a portion of the upstream body that borders the cutout, and
the upstream body includes bulging portions, each of which bulges from opposite sides in a thickness direction of the upstream body and is formed at a portion of the upstream body that borders one of the stoppers.

2. An air-conditioning register comprising:
a downstream fin including a downstream body and a downstream fin shaft, which are located in an extending direction crossing a flow direction of air-conditioning air, wherein the downstream fin is supported to pivot about the downstream fin shaft;
an upstream fin including
an upstream body and an upstream fin shaft, wherein each of the upstream body and the upstream fin shaft extends in a direction that crosses both the flow direction and the extending direction of the downstream fin shaft,
a cutout formed in the upstream body to extend upstream from a downstream edge of the upstream body, and
a transmission shaft that is located in the cutout to extend along the upstream fin shaft, wherein the upstream fin is located upstream of the downstream fin and supported to pivot about the upstream fin shaft;

an operation knob arranged to slide relative to the downstream body in the extending direction of the downstream body;
a fork including a pair of transmission pieces that extend upstream from the operation knob and that sandwich the transmission shaft, wherein the fork is supported with a support shaft to be rotational relative to the operation knob; and
a pair of stoppers arranged on the transmission shaft, wherein the stoppers are spaced from each other in the extending direction of the transmission shaft and located at positions that sandwich the transmission pieces, the stoppers are caused to contact the transmission pieces by operation of the operation knob, and the pair of stoppers limits a movable range of the transmission pieces to a distance between the pair of stoppers, wherein
each stopper includes a contact surface that contacts the transmission pieces,
a portion of the transmission shaft between the stoppers includes a columnar body shaft,
the contact surface of each stopper is formed by a portion of the stopper that borders the body shaft, and
the contact surface of each stopper is formed to have a truncated conical shape so that a diameter increases as a distance from the body shaft increases.
