Abstract: To provide an intake manifold which can reliably prevent the step from being formed in the inner wall surface of the intake passage (15) while having provided therein the fitting holding portion (32) for fitting and holding the flame arrester (25) in the axial direction, the intake manifold (10) includes a base member (21), a cover member (22) and a flame arrester (25) having a flame suppression structure. Between the flame arrester (25) and the radical stepped surface (31b) of the recessed body portion (31) is provided a retaining rectifying member (23) that prevents the flame arrester (25) from coming off with respect to the fitting holding portion (32) and forms a third inner peripheral surface (23a) continuous without a step from an opening portion on the other end side (25b) of the flame arrester (25) to the base side second inner wall surface (31c).

Abstract: An intake manifold includes: a surge tank, die-molded to temporarily store intake air; and branch pipes, in communication with the surge tank. The surge tank includes, on an outer wall thereof, a flange part and a reinforcement rib, a sensor unit configured to detect an intake air state quantity being installed to the a part. The flange part includes: a fitting hole, having an axis as a center to be fit with a detection part of the sensor unit; and boss parts, provided on a periphery of the fitting hole, and the flange part is formed to be rotationally symmetric with the axis as a center. The reinforcement rib includes a limitation piece interfering with a portion of the sensor unit to limit assembling at a time when the sensor unit is assembled erroneously for being deviated from a normal orientation.

Abstract: An intake manifold which can ensure a pressure resistance strength, a mechanical strength, and the like and also reduce a passage resistance and an outboard motor which can be made smaller and thinner in a width direction. A resinous intake manifold made of a resin and configured to be applied to an engine of an outboard motor includes: a surge tank which forms a flat contour and includes an intake inlet; and a plurality of branch pipes which defines intake passages communicating with an internal space of the surge tank, wherein a contour wall of the surge tank includes a plurality of ridge portions which protrudes toward the internal space and is oriented toward the intake passage side.
