低減される。 Next, to explain the operation of this embodiment, intake system noise is reduced by the resonator chamber 7 and the branch pipe 6.
However, when assembling the branch pipe 6, since the branch pipe 6 is divided into two relatively short first and second pipe members 17 and 18, it is easy to handle and the assembly is easy. This makes attaching work easier. Also 2
By being divided, it becomes possible to provide different material properties to both ends of the branch pipe 6. moreover,
When blow molding the first and second pipe members 17 and 18, a smaller mold is required, whereas when integrally molding the branch pipe 6, a smaller mold is required, and costs can be reduced. In addition, the branch pipe 6 having a complicated three-dimensional shape as a whole with the bent intermediate portion 6a is replaced by the first and second branch pipes each having a substantially linear simple shape.
By dividing the pipe members 17 and 18, blow molding becomes extremely easy, and manufacturing costs are further reduced.

Effects of the Invention As described above, according to the present invention, a branch pipe with a closed end and a bent middle part is installed in the middle of the intake pipe that connects to the combustion chamber of an internal combustion engine housed in the engine room of a vehicle. In the side branch intake system muffler for a vehicle internal combustion engine, the branch pipe includes a first pipe member on the intake pipe side and a second pipe member on the distal end side, which are connected to each other near the bending intermediate portion of the branch pipe. The first tube member is configured to be divided into:
The second pipe member is integrally molded from an elastic synthetic resin and has a bellows section in the middle, and the second pipe member is integrally molded from a heat-resistant synthetic resin and is supported by a support section in the engine room. Since the first pipe member is connected to a connecting member made of an elastic material that constitutes a part of the intake pipe, the entire branch pipe is made of synthetic resin, making it possible to reduce the weight even if the pipe has a long overall length. , the number of support parts for the tube can be reduced, contributing to the simplification of the support structure, and interference with other equipment can be easily avoided. In addition, even though there is a bent part in the middle of the branch pipe, the individual shapes of the first and second pipe members constituting the branch pipe can be made as close to a simple straight line as possible. It is relatively easy to individually mold the tube member, and the molding process for the entire tube member is simplified, which can contribute to cost reduction. Furthermore, the first pipe member is made of a synthetic resin that has elasticity, and is also provided with the bellows portion that is easily elastically deformed in the length direction, and furthermore, the first pipe member is a connecting member made of an elastic material that constitutes a part of the intake pipe. Since the intake pipe connected to the internal combustion engine and the second pipe member supported by the support part in the engine compartment are connected to the Even if severe relative displacement occurs, the relative displacement can be tolerated without difficulty, and there is no risk of excessive loads acting on the connections between the first pipe member and the intake pipe or between the first and second pipe members. There is no problem, and these connections can always be made accurately. Furthermore, the second pipe member made of heat-resistant synthetic resin has no risk of deformation or deterioration even if the support part in the engine room that supports it is a high temperature part, and it maintains the intended performance of the branch pipe. Can be maintained for a period of time. As mentioned above, since the first tube member, which requires elasticity, and the second tube member, which requires heat resistance, can be molded separately from different synthetic resin materials, these requirements can be influenced by each other. You can easily satisfy them without being overwhelmed.
