Kind Code:

A1

Abstract:

In order to prevent a stepped part from being formed on the inner wall surface of the intake passage of this intake manifold, a base member (21) into which a flame arrester (25) is incorporated comprises a recessed body (31) having an approximate split cylindrical shape and an annular fitting/holding section (32) to which the flame arrester (25) is fit in the axial direction. The fitting/holding section (32) comprises an abutment surface (32a) and an inner circumferential fitting wall surface (32b). The recessed body (31) comprises a first inner wall surface (31a) that is continuous with the inner circumferential fitting wall surface (32b) and a base-side second inner wall surface (31c) that is connected to the first inner wall surface (31a) via a radial stepped surface (31b). A retaining/rectifying member (23) provided between the flame arrester (25) and the stepped surface (31b) of the recessed body (31) retains the flame arrester (25) with respect to the fitting/holding section (32) and forms an inner circumferential surface (23a) that is continuous without stepped parts from an opening (25b) on the other end side of the flame arrester (25) to the base-side second inner wall surface (31c).
