Abstract
Provided is a damper of an air vent for a vehicle, in which an operating member and a pad member are assembled with a structure in which a coupling protrusion of the operating member is inserted into a coupling hole of the pad member. As dimensions of the damper become accurate, a gap is not formed, thereby preventing air leakage. Moreover, due to no need for overlap of the pad member, the operating force of the damper is reduced and becomes uniform, and friction noise of the pad member in operation is prevented. Furthermore, an assembly method is simple, facilitating automation and expecting productivity improvement.
Claims6
A damper of an air vent for a vehicle, the damper comprising:
- an operating member installed to pivot inside a housing of the air vent;
- and
- a pad member provided along a circumference of an end portion of the operating member and locked by a locking protrusion formed on an inner surface of the housing to prevent a flow path, wherein a support wall is formed in an end portion of a body plate of the operating member and a plurality of coupling protrusions are formed on the support wall,
- a coupling portion in a shape that is the same as a shape of the support wall is formed in the pad member, and a coupling hole one-to-one corresponding to the coupling protrusion is formed in the coupling protrusion, and
- the pad member is mounted on the operating member with a structure in which the coupling protrusion is insertedly coupled to the coupling hole,
- wherein the pad member comprises a reinforcing portion having a thickness greater than that of the coupling portion on an outer side of the coupling portion and a contact end formed to protrude on an outer side of the reinforcing portion,
- wherein the contact end comprises a first blocking portion and a second blocking portion respectively closely contacting a first contact surface and a second contact surface formed on the locking protrusion of the housing,
- wherein a recessed groove is formed between the reinforcing portion and the contact end, and a reinforcing portion-side surface of the recessed groove forms a surface that is perpendicular to a longitudinal direction of the coupling portion and a contact end-side surface of the recessed groove is formed as an inclined surface,
- wherein the first blocking portion and the second blocking portion are formed on one side of the contact end, and the recessed groove is formed on the other side of the contact end.
