検出装置。 A shift lever device for an automatic transmission is provided in a vehicle equipped with a shift lever device for an automatic transmission that activates a lock mechanism at a vehicle speed exceeding a predetermined value based on the vehicle speed detected by the vehicle speed detection means and disables a shift operation to a reverse shift position. A failure detection device for a vehicle speed detection means that detects a failure of the detection means, wherein the vehicle speed detection means, a shift position detection means provided in an automatic transmission and detecting a shift position, and an engine are in a power generating state. A power generation state detection means that directly or indirectly detects the vehicle speed is electrically connected to a non-braking state detection means that detects that the vehicle is not in a braking state by the braking device of the vehicle. At the same time, the shift position detection means detects that the shift position for driving is selected, the power generation state detection means detects that the engine is in the power generation state, and the non-braking state detection means detects that the engine is in the power generation state. 1. A failure detection device for a vehicle speed detection means, characterized in that when it is detected that the vehicle is not in a braking state, the vehicle speed detection means is determined to have failed and electrically outputs a failure signal.
