Abstract: An insulation diagnostic device according to an embodiment performs an insulation diagnosis of a three-phase AC motor on the basis of a U-phase current, a V-phase current, and a W-phase current supplied to the three-phase AC motor, and includes: a current vector calculation module that calculates at least one of a zero sequence current vector or a negative sequence current vector on the basis of the U-phase current, the V-phase current, and the W-phase current; a reference current vector storage unit that stores a reference current vector in advance; a current difference vector calculation module that calculates a current difference vector that is a difference between a current vector calculated by the current vector calculation module and the reference current vector; and a determination module that determines an insulation state of the three-phase AC motor on the basis of the current difference vector.

Abstract: When a shift lever is moved to a shift position corresponding to a first gear position etc., the shift lever is urged by its own weight to a neutral position, which is disadvantageous for the shift lever in terms of gear slip-out after shifting. However, a counter mass is moved to a position reached by turning a second predetermined angle, larger than a first predetermined angle corresponding to the neutral position, downward with respect to a vertical line passing through a center of turn of the counter mass. Meanwhile, the shift lever is urged by the weight of the counter mass in the direction away from the neutral position, so that gear slip-out after shifting can be prevented.
