Abstract

A wind direction adjuster is disclosed in which an inner-side turning axis provided to a louver main body in a protruding manner is axially supported by an inner-side axial support hole provided in a spacer fixed to a bearing portion provided to a housing portion. Moreover, an actuator axis provided to the louver main body in a protruding manner at a position spaced from the inner-side turning axis is inserted into an operation opening provided to the spacer. In addition, a louver moves forward or rearward by pushing the actuator axis by a projecting portion in association with turning of a knob turnable with respect to the bearing portion and the spacer. The louvers can be moved in conjunction with each other with a simple configuration.

First claim

The invention claimed is:

1. A wind direction adjuster comprising:
a housing portion including a cylindrical outer frame portion and a bearing portion, the outer frame portion having an inner side serving as a flow passage, the bearing portion being provided at a center axis side position of the cylindrical outer frame portion;
a fixing unit including an inner-side axial support portion and an operation opening that is formed along a circumferential direction, the fixing unit being fixed to the bearing portion;
an operation unit including a projecting portion, the operation unit being axially supported by the bearing portion turnably in the circumferential direction and being externally operable; and
a louver including a louver main body, an inner-side turning axis, and an actuator axis, the inner-side turning axis being provided to the louver main body in a protruding manner at a position facing the fixing unit, the inner-side turning axis being axially supported by the inner-side axial support portion, the actuator axis being provided to the louver main body in a protruding manner at a position of the louver main body that faces an outer circumference surface of the fixing unit and that is spaced from the inner-side turning axis, the actuator axis being inserted into the operation opening, the actuator axis being movable along the operation opening when the actuator axis is pushed by the projecting portion as the projecting portion is turned in the circumferential direction by a turning of the operation unit in the circumferential direction, the louver main body being disposed along a radial direction of the housing portion,
wherein:
the housing portion further includes an outer-side axial support portion
provided to the cylindrical outer frame portion, and
the louver further includes an outer-side turning axis provided to the louver main body in a protruding manner and configured to be axially supported by the outer-side axial support portion.

2. The wind direction adjuster according to claim 1 , wherein the inner-side turning axis is provided in a protruding manner at a more leeward position than the actuator axis in the louver main body.

3. The wind direction adjuster according to claim 1 , wherein the inner-side turning axis is provided in a protruding manner at a more windward position than the actuator axis in the louver main body.

4. The wind direction adjuster according to claim 3 , wherein:
the actuator axis includes:
a protruding portion that protrudes from the louver main body in a thickness direction of the louver main body;
a coupling portion that is bent towards the operation unit from the protruding portion; and
an insertion axis portion that is provided at a leading end portion of the coupling portion in a bent shape towards the operation unit so as to fold back in the thickness direction and that is inserted between the projecting portions of the operation unit and held by the projecting portions.

5. The wind direction adjuster according to claim 1 , further comprising:
a cylindrical outer portion configured to house the housing portion; and
a link unit that is axially supported turnably in a predetermined reciprocating direction with respect to the cylindrical outer portion and is configured to axially support the fixing unit turnably in another reciprocating direction intersecting with the predetermined reciprocating direction.

6. The wind direction adjuster according to claim 1 , wherein the louver includes a ventilation opening made by forming an opening that penetrates through the louver main body in a thickness direction of the louver main body.

7. The wind direction adjuster according to claim 1 , wherein:
the inner-side turning axis is axially supported by the inner-side axial support portion at a more leeward position than the outer-side turning axis; and
the inner-side turning axis and the outer-side turning axis are inclined towards a windward side with respect to the radial direction of the housing portion.
