An engine comprises a timer (), which is provided with a temperature-sensing operation mechanism (). During a cold-starting term, a downstream interlocking portion () advances by an advancing operation of the timer () based on an operation that the temperature-sensing operation mechanism () makes upon sensing the temperature. While the engine is warm, the downstream interlocking portion () cancels an advancement by an advancement-cancellation operation of the timer () based on another operation that the temperature-sensing operation mechanism () makes upon sensing the temperature. The engine oil () within the engine is supplied from the oil-supply port () to the timer (), thereby enabling the engine oil () in liquid state to contact the temperature-sensing operation mechanism ().
