Provided is a shaft component for manufacturing a bearing raceway component having a power transmission portion with teeth by performing carburizing or carbonitriding. The shaft component is made of a columnar or cylindrical shaft member. The shaft member has a central axis, a first portion on a first side in the axial direction, and a second portion on a second side of the first portion in the axial direction. The first portion is integrated with the second portion. The first portion is made of a first steel material, and the second portion is made of a second steel material. The first portion has a portion that becomes a raceway, and the second portion has a portion that becomes teeth. An alloy composition of the first steel material is different from an alloy composition of the second steel material. A third portion includes a joint surface that is connected to the second portion on the second side of the first portion in the axial direction, and a fourth portion includes a joint surface that is connected to the first portion on the first side of the second portion in the axial direction. A fifth portion is located on the first side of the third portion in the axial direction in the first portion, and a sixth portion is located on the second side of the fourth portion in the axial direction in the second portion. The hardness of the third portion is greater than the hardness of the fifth portion, and the hardness of the fourth portion is greater than the hardness of the sixth portion. The portion that becomes the raceway is located in the fifth portion and is not located in the third portion.

This bearing track component comprises a shaft member comprising a first portion and a second portion. The first portion is made of a first steel material containing a first alloy component, and the second portion is made of a second steel material containing a second alloy component. The first alloy component is different from the second alloy component. The first portion has a bearing part having a track, and the second portion has a power transmission part having teeth. The first portion has a first surface-hardened layer provided along the outer peripheral surface of the first portion, and a first inner part. The average hardness of the first surface-hardened layer is greater than the average hardness of the first inner part. The second portion has a second surface-hardened layer provided along the outer peripheral surface of the second portion, and a second inner part. The average hardness of the second surface-hardened layer is greater than the average hardness of the second inner part. The first surface-hardened layer and the second surface-hardened layer are both carburized layers or carbonitrided layers, and the first surface-hardened layer and the second surface-hardened layer are connected to each other.

A power source apparatus includes: an auxiliary power source; and a control circuit configured to control charging and discharging of the auxiliary power source. The control circuit is configured to, after completion of the initial check, charge the auxiliary power source after waiting for traveling preparation of the vehicle to be completed. The control circuit is configured to, after the completion of the initial check, charge the auxiliary power source when both of a first condition and a second condition are satisfied even before the completion of the traveling preparation of the vehicle. The first condition is a condition in which an amount of elapsed time from when the initial check is completed is equal to or more than a time threshold. The second condition is a condition in which voltage across the auxiliary power source is less than a voltage threshold.
