A rotor core includes a shaft hole, into which a shaft is inserted, and keys, which are protrusions corresponding to keyways of the shaft. A radial distance, which is the distance from the center of the shaft hole to an inner wall varies depending on the position in the circumferential direction of the shaft hole. The shaft hole includes key regions and increased diameter regions, in each of which the radial distance is longer than the radius of the shaft. Keys are respectively arranged in the key region. The shaft hole also includes contact regions, in which the shaft and the inner wall come into contact with each other when the shaft is inserted into the shaft hole. The contact regions are each located between the key regions or between the increased diameter regions. The contact regions are arranged at equal intervals in the circumferential direction.

A parameter for producing a positive electrode having excellent safety, and a positive electrode active material layer satisfying the parameter. The positive electrode active material layer includes a first positive electrode active material, a second positive electrode active material having a lower charge/discharge potential than the first positive electrode active material, and an additive. When the first positive electrode active material tap density is defined as dt, the second positive electrode active material tap density is defined as dt, a true density of the additive is defined as d, a mass percentage of the first positive electrode active material is defined as Wt, a mass percentage of the second positive electrode active material is defined as Wt, a mass percentage of the additive is defined as Wt, and a porosity of the positive electrode active material layer is defined as p, the positive electrode active material layer satisfies (1&#x2212;p)&#xd7;(Wt/dt)/((Wt/dt)+(Wt/dt)+(Wt/d))&#x3c;0.38.

A DC-AC converter for converting DC voltage to AC voltage. The converter includes a conversion circuit for converting DC voltage to voltage having a polarity corresponding to AC voltage. A filter circuit receives the converted voltage, smoothes the converted voltage, and outputs the smoothed voltage as AC voltage. A first switch operably connects the voltage conversion circuit and filter circuit. A second switch is arranged between input terminals of the filter circuit. An output current detection circuit detects overcurrent that is greater than a predetermined first threshold. When overcurrent that is greater than the first threshold is detected, the protection circuit stops the supply of power in the voltage conversion circuit, deactivates the first switch, and activates the second switch.
