The communication path interconnects the main chamber and the auxiliary chamber. The main chamber has, on one side which is derived from division by a line passing through the center of the auxiliary chamber when viewed in the axial direction of the cylinder, an intake port that introduces intake air to the main chamber, and has, on the other side, an exhaust port that discharges exhaust gas from the main chamber. The communication path includes a first communication path that is provided on a first straight line joining the center of the intake port to the center of the auxiliary chamber when viewed in the axial direction of the cylinder.
