Abstract: An atomizer includes a first piezoelectric pump, a first flow path, a reservoir part, and a second flow path. The first piezoelectric pump ejects gas through an outlet. The first flow path has a first end and a second end. The first end of the first flow path is connected to the outlet of the first piezoelectric pump. A connection point is provided between the first and second ends of the first flow path. Liquid is to be stored in the reservoir part. The second flow path has a first end and a second end. The first end of the second flow path is connected to the liquid reservoir part. The second end of the second flow path is connected to the connection point.

Abstract: A drive unit and a rear cushion overlap each other in a vehicle front view. Since the rear cushion is disposed to overlap the drive unit, the dimension in a vehicle width direction can be made smaller than that in the case where the cushion is disposed on the vehicle width center side of the drive unit.

Abstract: A strut suspension is disposed on a vehicle front side of a rotation center of a front wheel. A rack and pinion mechanism is disposed on a vehicle front side of the strut suspension. Since the strut suspension and the rack and pinion mechanism are disposed on the vehicle front side of the rotation center of the front wheel, a foot space can be moved forward to a position where the foot space overlaps the front wheel. A vehicle cabin space can be thereby increased.

Abstract: In an electric vehicle, a bearing supporting portion supporting another end of a motor shaft is provided in a reducer case and protrudes to a recessed portion while extending at a lateral side of the knuckle. The reducer case being part of a drive unit is partially housed in the recessed portion of a wheel. The drive unit can be located closer to a rear wheel by an amount corresponding to the housed portion. Accordingly, it is possible to dispose part of the drive unit inside the wheel and thereby suppress protruding of the drive unit to a small degree.
