Claims

[Scope of Claim for Utility Model Registration] A thermostat is housed horizontally inside the thermostat, and a cooling water suction passage from the radiator and a suction passage to the water pump have their respective axes aligned with the axes of the thermostat. In the thermostat cases of the engines that are connected in such a way that they are connected to each other, the opening of the bottom bypass passage to the thermostat case is arranged so that the center of the opening to the thermostat case is approximately aligned with the axis of the thermostat. A thermostat case for an engine, characterized in that a passage extends upward from the opening and is provided with a through hole that communicates a ceiling portion in the thermostat case with a bottom bypass passage.
