Abstract: A server acquires a current position of each of a plurality of battery transport mobile bodies transporting a first battery, acquires a current position of each of a plurality of electric mobile bodies and a charge rate of a second battery included in each of the plurality of electric mobile bodies, calculates a current charge rate for each of a plurality of sections on a map based on a charge rate of at least one second battery present in each of the plurality of sections, determines an insufficient charge section having a current charge rate lower than a target charge rate among the plurality of sections, and outputs control information for moving at least one battery transport mobile body among the plurality of battery transport mobile bodies to the determined insufficient charge section.

Abstract: A stabilizer having a tubular shape is provided so as to extend in a widthwise direction of a vehicle and coupled to a suspension arm at opposite end portions of the stabilizer. Each of the opposite end portions includes: a first large-diameter bar portion having an outside diameter greater than an outside diameter of an intermediate portion of the stabilizer; and a second large-diameter bar portion having an outside diameter greater than the outside diameter of the first large-diameter bar portion and having a wall thickness greater than a wall thickness of the intermediate portion.
