Description

자동차용 에어클리너와 공명기덕트 결합장치{Connecting structure of an air cleaner and resonator duct for a automobile}Connecting structure of an air cleaner and resonator duct for a automobile}

본 발명은 자동차용 에어클리너와 공명기덕트 결합장치에 관한 것으로써, 보다 상세히는 에어클리너와 공명기덕트의 결합성을 향상시켜 에어클리너와 공명기덕트를 결합한 상태에서 운반하는 도중 부주의하더라도 서로 분리되지 않아 이를 다시 결합해주어야 하는 작업을 삭제할 수 있음에 따라 작업성이 향상되는 것이고, 또한 기밀성을 향상시켜 엔진의 흡기밸브를 여닫을 때 발생되는 맥동소음이 에어클리너를 거쳐 공명기덕트로 유입시 일부가 외부로 빠져나가는 것을 효과적으로 방지하여 차량의 실내에서 소음을 감지하지 못하여 승차감을 향상시킬 수 있도록 한 자동차용 에어클리너와 공명기덕트 결합장치에 관한 것이다.The present invention relates to an air cleaner and resonator duct coupling device for automobiles, and more particularly, to improve the bondability between the air cleaner and the resonator duct, even if inadvertently separated during transportation in combination with the air cleaner and the resonator duct is not separated from each other As work that needs to be recombined can be deleted, workability is improved, and airtightness is also improved, so that the pulsation noise generated when opening and closing the intake valve of the engine passes through the air cleaner to the resonator duct, and some of it escapes to the outside. The present invention relates to a vehicle air cleaner and a resonator duct coupling device which effectively prevents noise and improves riding comfort by not detecting noise in a vehicle interior.

일반적으로 자동차는 연료와 공기가 혼합된 혼합기를 연소시키면서 동력을 발생하게 되는 것으로 즉, 자동차의 연료탱크에 저장되어 있다가 각종 연료공급장치를 통과한 연료가 외부로 부터 유입된 공기와 혼합되어 혼합기로 생성된후 이 혼합기가 엔진의 실린더로 분사됨과 동시에 엔진이 흡입, 압축, 폭발, 배기행정을 반 복하면서 작동하게 되고 이에따라 자동차가 동력을 얻게된다.In general, a vehicle generates power by burning a mixture of fuel and air, that is, fuel stored in a fuel tank of a vehicle and passed through various fuel supply devices is mixed with air introduced from the outside. After mixing, the mixer is injected into the engine's cylinders, and the engine operates in a repeating intake, compression, explosion, and exhaust stroke, thereby powering the car.

이처럼 엔진을 운전하는데에는 일정량의 공기를 필요로 하며, 이러한 공기의 공급은 자동차의 외부로 부터 공급되는데 이때 공급되는 공기는 정화되지 않은 상태이므로 먼지나 모래 또는 각종 이물질이 공기와 함께 유입됨에 따라 먼지나 모래 또는 이물질이 포함된 공기가 기화기를 거쳐 혼합기로 생성된후 실린더에 흡입되면 상기 먼지나 모래, 이물질이 고속으로 왕복하는 피스톤과 실린더벽에 상처를 입히게 되는 것은 물론 엔진오일에 혼합되므로 각 접동부분에 마모를 촉진하고 엔진의 수명을 단축시키게 된다.As such, a certain amount of air is required to operate the engine, and this air supply is supplied from the outside of the vehicle. At this time, since the air supplied is unpurified, dust, sand, or various foreign substances are introduced into the dust together with the air. When air containing sand or foreign matter is generated through a carburetor, and then sucked into the cylinder, the dust, sand, and foreign matter are wound on the piston and cylinder wall that reciprocate at high speed, and are mixed in the engine oil. This will promote wear on the parts and shorten the life of the engine.

이에따라 쓰로틀바디 앞쪽에 에어클리너를 장착하고 그 에어클리너에 에어인테이크 덕트를 설치하여 공기중에 포함된 대부분의 먼지나 모래, 이물질등을 에어인테이크 덕트를 통해 흡입한후 에어클리너로 들여보내도록 한 것이다.Accordingly, an air cleaner was installed in front of the throttle body and an air intake duct was installed in the air cleaner to suck most of the dust, sand, and foreign substances contained in the air through the air intake duct, and then to be introduced into the air cleaner.

한편, 자동차의 소음은 엔진의 흡기 또는 배기계통으로 부터 발생되는 소음이 주류를 이루는데 배기계통의 소음은 배기가스의 배출시 생성되는 것이므로 배기머플러를 이용하여 해소할 수 있지만 흡기계통의 소음은 엔진의 흡기밸브가 주기적으로 개폐될 때 밸브의 마찰음이나 연소실내부의 높은 압력에 의해 발생된다.On the other hand, the noise of the automobile is mainly generated by the engine intake or exhaust system. The noise of the exhaust system is generated when exhaust gas is discharged. Therefore, the noise of the intake system can be solved by the exhaust muffler. When the intake valve of the valve is periodically opened and closed, it is generated by the friction sound of the valve or the high pressure in the combustion chamber.

특히, 엔진의 흡기밸브가 닫혀질때 유체의 운동에너지는 압력에너지로 변환되면서 커다란 종파가 발생되는데 밸브로부터의 이러한 골과 산들은 에어 인테이크덕트로 나와 토출음으로 발생되고, 이러한 소음은 운전자나 탑승자에게 불쾌한 소음으로 작용하게 되어 근래에는 단순히 외부의 공기를 에어클리너로 안내하는 역할만을 하는 에어인테이크덕트 대신에 에어인테이크덕트에 헬름헬츠공명기를 부착한 공명기덕트를 사용하여 엔진의 흡기밸브가 닫혀질때 발생되는 소음이 에어클리너를 통해 공명기덕트로 유입되면 이를 상쇄시켜 차 실내에서는 소음을 인지할 수 없도록 하므로서 승차감을 향상시킬 수 있도록 한다.In particular, when the intake valve of the engine is closed, the kinetic energy of the fluid is converted into pressure energy, and a large longitudinal wave is generated. These valleys and acids from the valve come out of the air intake duct and are generated by the discharge sound. This is caused by an unpleasant noise, which is caused when the intake valve of the engine is closed by using a resonator duct with a Helm Helms resonator attached to the air intake duct instead of an air intake duct that merely guides the outside air to the air cleaner. When the noise enters the resonator duct through the air cleaner, the noise is canceled so that the passengers cannot recognize the noise inside the car, thereby improving the riding comfort.

그런데 종래 에어클리너와 공명기덕트와의 결합구조는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.By the way, the conventional structure of the air cleaner and the resonator duct coupling there are many problems as described in detail as follows.

도 1 은 종래 에어클리너와 공명기덕트가 결합된 상태를 도시한 요부 도면으로서 즉, 에어클리너(10)와 공명기덕트(20)는 엔진룸에 장착된 상태에서 서로 결합하는 것이 아니라 외부에서 에어클리너(10)와 공명기덕트(20)를 서로 조립한후 이를 통째로 엔진룸으로 옮겨와 장착하는 것인데 종래에는 에어클리너(10)와 공명기덕트(20)의 결합이 단순끼움 방식이므로 운반자가 에어클리너(10)와 공명기덕트(20)를 결합한 상태에서 운반하는 도중 약간만 부주의하여도 에어클리너(10)와 공명기덕트(20)가 서로 쉽게 분리되어 이를 다시 결합해 주어야 하는 번거로움이 있어 그만큼 작업성이 저하되는 문제점이 있었다.1 is a main view illustrating a state in which a conventional air cleaner and a resonator duct are coupled to each other, that is, the air cleaner 10 and the resonator duct 20 are not coupled to each other in a state in which they are mounted in an engine room, but instead are connected to an air cleaner from the outside. 10) and the resonator duct (20) after assembling each other to move and install the whole engine room, but conventionally the combination of the air cleaner 10 and the resonator duct 20 is a simple fitting method so that the carrier air cleaner (10) And the resonator duct 20 is coupled to the air cleaner 10 and the resonator duct 20, even if only a little carelessly during transportation, there is a hassle to be easily separated from each other to combine them again, the workability is reduced as much There was this.

또한 종래에는 기밀성을 향상시키기 위하여 공명기덕트(20)의 결합부(21)외주면에 신축성 있는 패드(30)를 부착한 상태에서 에어클리너(10)의 출구(11)에 공명기덕트(20)의 결합부(21)가 끼워져 결합되게 하는 것이다.In addition, in the related art, the resonator duct 20 is coupled to the outlet 11 of the air cleaner 10 while the elastic pad 30 is attached to the outer circumferential surface of the coupling portion 21 of the resonator duct 20 to improve airtightness. The part 21 is fitted to be coupled.

그런데 공명기덕트(20)의 결합부(21)외주면에 패드(30)를 부착한 상태에서 공명기덕트(20)의 결합부(21)를 에어클리너(10)의 출구(11)에 끼울시 약간만 부주의하거나 패드(30)가 견고하게 부착되어 있지 않으면 패드(30)가 밀려서 원래의 위치에 고정되어 있지 않고, 외측으로 약간 밀리면서 에어클리너(10)의 출구(11)와 공명기덕트(20)의 결합부(21)사이에 약간의 틈새가 발생되는데 이를 그대로 방치한채 차량에 장착할 경우 엔진의 흡기밸브가 닫힐 때 나는 소음이 에어클리너(10)를 통한후 공명기덕트(20)로 유입시 전량 유입되지 못하고, 일부 소음이 그 틈새를 통하여 외부로 빠져나가게 되어 차량의 실내에서 탑승자들이 그 소음을 그대로 인지하여 불쾌감을 느끼므로서 승차감이 떨어지는 문제점이 있었다.However, when the coupling part 21 of the resonator duct 20 is fitted to the outlet 11 of the air cleaner 10 in a state in which the pad 30 is attached to the outer peripheral surface of the coupling part 21 of the resonator duct 20, only a slight carelessness is caused. If the pad 30 is not firmly attached, the pad 30 is pushed and not fixed to its original position, but slightly pushed outward so that the outlet 11 of the air cleaner 10 and the resonator duct 20 are coupled to each other. There is a slight gap between the parts 21. If it is left unchanged and is mounted on the vehicle, the noise generated when the intake valve of the engine is closed is not introduced into the resonator duct 20 after the air cleaner 10 is closed. There is a problem that some noise is to escape to the outside through the gap, the passengers in the interior of the vehicle as the passengers perceive the noise as it is unpleasant, there is a problem in riding comfort falls.

이에 본 발명은 이와같은 종래의 문제점을 해결하기 위한 것으로 본 발명의목적은 에어클리너와 공명기덕트를 결합한 상태에서 운반하더라도 에어클리너와 공명기덕트가 서로 분리되는 일이 없어 작업성을 향상시킬 수 있는 자동차용 에어클리너와 공명기덕트의 결합장치에 관한 것이다.Therefore, the present invention is to solve such a conventional problem, the object of the present invention even when transported in the air cleaner and resonator duct combined state does not separate the air cleaner and the resonator duct car can improve workability The present invention relates to a combination device of an air cleaner and a resonator duct.

본 발명의 다른목적은 에어클리너와 공명기덕트의 기밀성이 향상되어 엔진의 흡기밸브에서 발생한 소음이 에어클리너에서 공명기덕트로 유입시 일부 소음이 외부로 빠져나가는 것을 효과적으로 방지하여 차량의 실내에서 소음을 인지하지 못하도록 하므로서 승차감을 향상시킬 수 있도록 한 자동차용 에어클리너와 공명기덕트 결합장치에 관한 것이다.Another object of the present invention is to improve the airtightness of the air cleaner and the resonator duct to effectively prevent some noise to escape to the outside when the noise generated from the intake valve of the engine flows into the resonator duct from the air cleaner to recognize the noise in the interior of the vehicle The present invention relates to a vehicle air cleaner and a resonator duct coupling device that improves ride comfort by preventing the user from riding.

위의 목적을 달성하기 위해 본 발명은 자동차용 에어클리너와 공명기덕트를 서로 결합함에 있어서, 에어클리너의 출구 선단에는 " 』"형으로 끼움홈과 안착홈이 연결되도록 형성하고, 출구에 끼워져 결합되는 공명기덕트의 결합부에는 끼움홈을 통해 끼워지고 안착홈에 걸리는 걸림돌기를 형성하여 된 것을 특징으로 한다.In order to achieve the above object of the present invention in the coupling of the air cleaner and the resonator duct for the vehicle, the outlet end of the air cleaner is formed so that the fitting groove and the seating groove is connected to the outlet of the "'" type, is fitted into the outlet The coupling portion of the resonator duct is characterized in that it is formed through the fitting groove is formed through the engaging groove is caught in the seating groove.

다른목적을 달성하기 위해 본 발명은 공명기덕트의 결합부 외주면에는 걸림돌기 전방에 설치홈을 형성하고, 그 설치홈에는 패킹부재를 설치하여 에어클리너의 출구 내주면과의 사이를 밀폐시키도록 한 것을 특징으로 한다.In order to achieve the other purpose, the present invention is characterized in that the outer peripheral surface of the coupling portion of the resonator duct to form an installation groove in front of the engaging projection, the installation groove is installed to seal the gap between the inner peripheral surface of the outlet of the air cleaner. It is done.

이와같은 본 발명은 에어클리너와 공명기덕트의 결합구조를 개선하여 에어클리너와 공명기덕트를 결합한 상태에서 운반하더라도 서로 분리되는 일이 없어 작업성을 향상시킬 수 있는 것이며, 또한 기밀성이 향상되어 엔진의 흡기밸브가 닫힐때 발생되는 소음이 에어클리너를 통해 공명기덕트로 유입시 일부가 외부로 새어나갈 우려가 없도록 하므로서 탑승자가 소음을 인지하지 못하여 승차감을 향상시킬 수 있도록 한 것이다.The present invention improves the coupling structure of the air cleaner and the resonator duct to improve workability without being separated from each other even when transported in a combined state of the air cleaner and the resonator duct. The noise generated when the valve is closed is prevented from leaking to the outside when inflow into the resonator duct through the air cleaner, so that the passenger can not recognize the noise and improve the riding comfort.

이하 본 발명의 특징을 효과적으로 달성할 수 있는 바람직한 실시예로서 그 기술구성 및 작용효과를 첨부된 도면에 의해 상세히 설명하면 다음과 같다. Hereinafter, with reference to the accompanying drawings, the technical configuration and operation effects as a preferred embodiment that can effectively achieve the features of the present invention will be described.

도 2 는 본 발명에 따라 에어클리너와 공명기덕트가 결합되기전의 상태를 예시한 요부 분리사시도이고, 도 3 은 본 발명에 따라 에어클리너와 공명기덕트가 결 합된 상태를 예시한 요부 정면도이며, 도 4 는 본 발명에 따라 에어클리너와 공명기덕트가 결합된 상태를 예시한 요부 단면도이다.2 is an exploded perspective view of the main part illustrating a state before the air cleaner and the resonator duct is coupled in accordance with the present invention, Figure 3 is a front view of the main part illustrating a state in which the air cleaner and the resonator duct is coupled in accordance with the present invention, Figure 4 Is a sectional view of the main portion illustrating a state in which the air cleaner and the resonator duct are coupled according to the present invention.

이러한 본 발명은 자동차용 에어클리너와 공명기덕트를 결합함에 있어서, 에어클리너(100)의 출구(110) 선단에는 " 』"형으로 끼움홈(111)과 안착홈(112)이 연결되도록 형성하고, 출구(110)에 끼워져 결합되는 공명기덕트(200)의 결합부(210)에는 끼움홈(111)을 통해 끼워지고 안착홈(112)에 걸리는 걸림돌기(211)를 형성하여 된 것을 특징으로 한다.In the present invention is coupled to the air cleaner and the resonator duct in the car, the end of the outlet 110 of the air cleaner 100 is formed so that the fitting groove 111 and the seating groove 112 is connected to the "'" type, The engaging portion 210 of the resonator duct 200 to be fitted into the outlet 110 is characterized in that the engaging projection 211 is fitted through the fitting groove 111 and is caught by the mounting groove 112.

이와같은 본 발명은 에어클리너(100)와 공명기덕트(200)를 외부에서 서로 결합시킨후 이를 통째로 운반하여 엔진룸(도면중 미도시)에 장착하고, 엔진의 흡기밸브가 닫힐때 발생되는 소음을 에어클리너(100)를 통해 공명기덕트(200)로 들여보내 소음을 저감시켜서 차량에 탑승한 승객들의 승차감을 향상시키도록 한 것은 종래와 마찬가지이다.In the present invention, the air cleaner 100 and the resonator duct 200 are coupled to each other from the outside and then transported to the engine room (not shown in the drawing), and the noise generated when the intake valve of the engine is closed. The air cleaner 100 is introduced into the resonator duct 200 to reduce noise and improve ride comfort of passengers in the vehicle.

그러나 본 발명에서의 특징은 에어클리너(100)와 공명기덕트(200)를 서로 결합한 상태에서 이를 통째로 운반하더라도 서로 분리될 우려가 없어 작업성을 향상시킬 수 있는 것이고, 소음이 에어클리너(100)에서 공명기덕트(200)로 유입될 시 일부 소음이 외부로 새어나가는 것을 효과적으로 방지하여 탑승자의 승차감을 향상시킬 수 있도록 한 것이다.However, in the present invention, even if the air cleaner 100 and the resonator duct 200 are transported together in a state where they are coupled to each other, there is no fear that they may be separated from each other, thereby improving workability, and the noise from the air cleaner 100. When entering the resonator duct 200 is to effectively prevent some noise leaking to the outside to improve the ride comfort of the occupants.

즉, 본 발명은 도2에서와 같이 에어클리너(100)의 출구(110)에 "』"형으로 이루어진 끼움홈(111)과 안착홈(112)을 형성하고, 공명기덕트(200)의 결합부(210)에는 걸림돌기(211)를 형성하였으므로 에어클리너(100)와 공명기덕트(200)를 서로 결합시에는 우선 공명기덕트(200)의 결합부(210)를 에어클리너(100)의 출구(110)속으로 끼워 걸림돌기(211)가 끼움홈(111)으로 끼워지게 공명기덕트(200)를 밀어준다.That is, the present invention forms a fitting groove 111 and a seating groove 112 formed of a "" "type in the outlet 110 of the air cleaner 100, as shown in Figure 2, the coupling portion of the resonator duct 200 Since the engaging protrusion 211 is formed at 210, when the air cleaner 100 and the resonator duct 200 are coupled to each other, the engaging portion 210 of the resonator duct 200 is first exited by the outlet 110 of the air cleaner 100. ) Push the resonator duct 200 to be fitted into the engaging projection 211 is fitted into the fitting groove (111).

이처럼 걸림돌기(211)를 끼움홈(111)으로 끼워 걸림돌기(211)가 끼움홈(111)끝단에 위치되어 더이상 걸림돌기(211)가 전진되지 못하면 공명기덕트(200)를 시계 반대방향으로 회전시켜 걸림돌기(211)가 안착홈(112)으로 들어가 걸리도록 하면 공명기덕트(200)와 에어클리너(100)는 서로 견고한 결합이 되어 인위적으로 분리시키지 않는 이상 분리되지 않는다.As such, when the locking protrusion 211 is inserted into the fitting groove 111 and the locking protrusion 211 is positioned at the end of the fitting groove 111 and the locking protrusion 211 is not moved forward, the resonator duct 200 is rotated counterclockwise. Resonator duct 200 and the air cleaner 100 is a solid coupling with each other is not separated unless artificially separated so that the engaging projection 211 is caught into the seating groove 112.

여기서 에어클리너(100)와 공명기덕트(200)를 결합시 위에서 언급한 바와같이 에어클리너(100)는 고정시킨 상태에서 공명기덕트(200)를 반시계방향으로 돌려 걸림돌기(211)가 안착홈(112)에 걸리도록 하여도 되고, 반대로 공명기덕트(200)는 고정된 상태에서 에어클리너(100)를 시계방향으로 돌려 걸림돌기(211)가 안착홈(112)에 걸리도록 하여도 무방하다.Here, when combining the air cleaner 100 and the resonator duct 200, as described above, the resonator duct 200 is rotated counterclockwise in a state where the air cleaner 100 is fixed, and the locking protrusion 211 has a seating groove ( 112 may be caught, and conversely, the resonator duct 200 may rotate the air cleaner 100 clockwise in a fixed state so that the locking protrusion 211 is caught by the seating groove 112.

이렇게 에어클리너(100)와 공명기덕트(200)를 결합하게 되면 인위적으로 분리하지 않는 이상 서로 분리되지 않으므로 에어클리너(100)와 공명기덕트(200)를 결합하여 통째로 운반도중 운반자가 부주의하더라도 에어클리너(100)와 공명기덕트(200)가 서로 분리되는 일이 없어 종전처럼 재결합 하여야 하는 번거로움이 없어 그만큼 작업성이 향상되는 것이다.When the air cleaner 100 and the resonator duct 200 are combined as described above, they are not separated from each other unless they are artificially separated. 100) and the resonator duct 200 is not separated from each other, there is no hassle to recombine as before, so the workability is improved.

그리고 본 발명에서는 공명기덕트(200)의 결합부(210) 외주면에 형성된 걸림돌기(211)의 전방으로 설치홈(212)을 형성하고, 그 설치홈(212)에는 패킹부 재(300)를 설치하여 기밀성을 향상시킨 것이므로 즉, 패킹부재(300)가 에어클리너(100)의 내주면과 공명기덕트(200)의 외주면을 밀폐시켜 소음이 외부로 빠져나가는 것이 방지되는 것인데 여기서 패킹부재(300)를 설치홈(212)에 끼운 상태에서 에어클리너(100)와 공명기덕트(200)를 서로 결합시키는 것이므로 패킹부재(300)가 한쪽으로 치우쳐 들뜰 우려가 없는 것이다.In the present invention, the installation groove 212 is formed in front of the engaging projection 211 formed on the outer peripheral surface of the coupling portion 210 of the resonator duct 200, and the packing portion 300 is installed in the installation groove 212 That is, since the airtightness is improved, that is, the packing member 300 seals the inner circumferential surface of the air cleaner 100 and the outer circumferential surface of the resonator duct 200 to prevent noise from escaping to the outside, where the packing member 300 is installed. Since the air cleaner 100 and the resonator duct 200 are coupled to each other while being inserted into the groove 212, the packing member 300 is biased to one side and there is no fear of lifting.

또한 공명기덕트(200)의 결합부(210)에 형성된 걸림돌기(211) 후방에는 에어클리너(100)의 출구(110) 선단을 가려주는 걸림턱(213)을 형성하여 걸림돌기(211)의 파손을 방지하고, 기밀성을 더욱 향상시킨 것이다.In addition, behind the locking projection 211 formed in the coupling portion 210 of the resonator duct 200 to form a locking projection 213 to cover the tip of the outlet 110 of the air cleaner 100 to damage the locking projection 211. And further improve the airtightness.

즉, 에어클리너(100)와 공명기덕트(200)를 결합하기 위해서는 공명기덕트(200)의 결합부(210)에 형성된 걸림돌기(211)를 에어클리너(100)의 출구(110)에 형성된 끼움홈(111)에 끼워지게 하여 걸림돌기(211)가 끼움홈(111)끝단에 위치되면 에어클리너(100)나 공명기덕트(200)의 전진을 멈추고, 에어클리너(100)나 공명기덕트(200)를 회전시켜 걸림돌기(211)가 안착홈(112)속으로 들어가 걸리도록 하는 것은 위에서 언급한 바와같다.That is, in order to couple the air cleaner 100 and the resonator duct 200, the fitting protrusion 211 formed at the engaging portion 210 of the resonator duct 200 is formed in the outlet 110 of the air cleaner 100. When the engaging protrusion 211 is positioned at the end of the fitting groove 111, the air cleaner 100 or the resonator duct 200 is stopped, and the air cleaner 100 or the resonator duct 200 is stopped. Rotating projection 211 is to enter into the mounting groove 112 is caught as described above.

그런데 작업자가 걸림돌기(211)가 끼움홈(111)의 끝단에 위치되었는데도 불구하고 이를 무시하고 강한 힘으로 계속해서 에어클리너(100)나 공명기덕트(200)를 무리하게 전진시키면 걸림돌기(211)가 파손될 우려가 있기 때문에 걸림돌기(211)의 후방에 걸림턱(213)을 형성하여 걸림돌기(211)가 끼움홈(111)끝단에 위치되는 것과 동시에 에어클리너(100)의 출구(110)선단 주연이 걸림턱(213)에 걸리게 하여 더이상 에어클리너(100)나 공명기덕트(200)가 전진되지 못하도록 하므로서 걸림돌 기(211)의 파손됨을 방지할 수 있는 것이다.By the way, even if the worker is caught at the end of the fitting protrusion (211) fitting groove 111, and ignores this if you continue to advance the air cleaner 100 or resonator duct 200 forcibly with a strong force, the locking protrusion (211) May be damaged, so the locking projection 211 is formed at the rear of the locking projection 211 so that the locking projection 211 is positioned at the end of the fitting groove 111 and at the end of the outlet 110 of the air cleaner 100. It is possible to prevent the breakage of the catching protrusion 211 by preventing the air cleaner 100 or the resonator duct 200 from moving forward by causing the peripheral edge to catch the catching jaw 213.

또한 이러한 걸림턱(213)은 걸림돌기(211)의 파손을 방지하는 역할 이외에 공명기덕트(200)의 결합부(210)외주면과 에어클리너(100)의 출구(110) 내주면과의 사이를 밀폐시키는 패킹부재(300)와 더불어 이중으로 밀폐시켜서 소음이 외부로 빠져나가는 것이 더욱 효과적으로 방지된다.In addition, the locking jaw 213 serves to seal the gap between the outer peripheral surface of the coupling portion 210 of the resonator duct 200 and the inner peripheral surface of the outlet 110 of the air cleaner 100 in addition to preventing damage of the locking protrusion 211. Sealing the double with the packing member 300, the noise is more effectively prevented from escaping to the outside.
