To prevent a theft by a simple constitution.SOLUTION: A theft prevention device 1 comprises: a plurality of gear rows which are different in gear ratios; a drive mechanism for bringing a first selected gear row being a selected one gear row out of the plurality of gear rows into a power transmission state; an interlock mechanism which can regulate at least one gear row other than the first selected gear row so as not to be brought into the power transmission state; and a control part for making an output shaft 4 non-rotatable by bringing second selected gear rows (for example, a third-speed gear row 13, a fifth-speed gear row 15) being selected two gear rows out of the plurality of gear rows into the power transmission state having no regulation by the interlock mechanism by controlling the drive mechanism when a preset prescribed condition is satisfied during a stop of a vehicle.SELECTED DRAWING: Figure 11
【課題】簡易な構成で盗難を防止する。【解決手段】盗難防止装置1は、互いにギヤ比が異なる複数のギヤ列と、複数のギヤ列のうち、選択された1つのギヤ列である第1選択ギヤ列を動力伝達状態とする駆動機構と、第1選択ギヤ列ではない少なくとも1つのギヤ列を、動力伝達状態とならないように規制可能なインターロック機構と、車両の停止中、予め設定された所定条件を満たすと、駆動機構を制御して、複数のギヤ列のうち、選択された2つのギヤ列である第2選択ギヤ列(例えば、3速ギヤ列13、5速ギヤ列15)をインターロック機構による規制のない状態で動力伝達状態とすることで、出力軸4を回転不可とする制御部と、を備える。【選択図】図11
