ール冷却装置。[Scope of Claim for Utility Model Registration] A multi-cylinder rotary piston engine comprising: a rotor housing that accommodates a rotor; a spark plug support formed in the rotor housing that supports a spark plug; and a rotor housing that extends along the cylinder row direction. In a plug hole cooling device for a rotary piston engine, which includes a cooling water passage formed inside the cooling water passage and cooling the spark plug with cooling water, the ignition rate is lower in the cylinder on the downstream side of the cooling water passage than in the cylinder on the upstream side. A plug hole cooling device for a rotary piston engine, characterized in that the contact area between a plug support portion and a spark plug is set to be large.
