Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure that can set a defrosting processing time that is close to a time practically necessary for defrosting processing.SOLUTION: A defrosting controlling device includes: a defrosting control part for controlling defrosting processing for a frozen reductant agent in a selectable catalytic reduction system; and a setting part for setting a time to be taken for defrosting processing this time so as to be inversely correlated with the time taken for the defrosting processing last time when the defrosting processing last time ends halfway.SELECTED DRAWING: Figure 3 【課題】実際に解凍処理で必要となる時間に、近い解凍処理時間を設定し得る構造を実現する。【解決手段】選択触媒還元システムにおいて凍結した還元剤の解凍処理を制御する解凍制御部と、前回の解凍処理が途中で終了した場合に、前回の解凍処理にかかった時間と逆相関になるように、今回の解凍処理にかける時間を設定する設定部とを備えるように構成する。【選択図】図３
