れる。As described above, in the resin intake manifold of the present invention, the heat of the valve connecting portion, which becomes high in temperature, is transferred to the heat insulator via the second fastening member. Since it is fastened by the first fastening member that is different from the mounting portion of the intake manifold made of resin, the amount of heat transferred to the resin made intake manifold is extremely small due to the heat insulating effect of the heat insulator. Therefore, deterioration of the resin intake manifold due to high temperature can be prevented. In addition, if one end of the second fastening member is exposed in the space, not only the cooling effect of the second fastening member can be expected, but also the air heat insulating effect can be expected, so that the heat transfer amount from the valve connecting portion to the mounting portion is further increased. Can be kept small.
