Abstract
An evaporated fuel adsorbing mechanism for an internal combustion engine includes an adsorbing member provided in an intake passage of the internal combustion engine to adsorb evaporated fuel that flows back through the intake passage when the engine is stopped. The adsorbing member includes a connecting portion connected to an inner peripheral surface of the intake passage, an end portion that is away from the inner peripheral surface, and that is disposed downstream of the connecting portion in an intake-air flow direction in which intake air flows, and an upstream-side surface that faces toward an upstream side in the intake-air flow direction, and a downstream-side surface that faces toward a downstream side in the intake-air flow direction. The upstream-side surface and the downstream-side surface extend from the connecting portion to the end portion.
