Abstract: A wiper for a vehicle is provided with: an arm-side connection section; a blade-side connection section; support shafts which protrude from side walls of the blade-side connection section; and shaft support recesses which are provided in the arm-side connection section. When a wiper blade is located in a mounting-dismounting enabled region, the mounting-dismounting openings and the small-diameter sections of the support shafts match with each other, and the support shafts and the shaft support recesses can be mounted to and dismounted from each other. When the wiper blade is located in a mounting-dismounting disabled region, the mounting-dismounting openings and the small-diameter sections do not match with each other, and the support shafts and the shaft support recesses cannot be mounted to and dismounted from each other. A shape retaining section is located between the pair of the shaft support recesses.

Abstract: A vehicle window opening device includes an open-close controller, a drawing determination unit, a restriction unit, and an initial mask zone setting unit. The drawing determination unit determines that a vehicle window has drawn in an object when a characteristic value of a motor is greater than or equal to a determination threshold value. The open-close controller executes anti-drawing control based on the drawing determination. The restriction unit restricts the open-close controller from executing the anti-drawing control when the vehicle window is located in the initial mask zone. The initial mask zone setting unit sets an initial mask zone to a normal value when a position where the vehicle window starts to open is located outside a fully closed region and to a fully closed region value that is greater than the normal value when the position where the vehicle window starts to open is located in the fully closed region.

The manufacturing method further includes forming the contact portion from the projection by performing a contraction pressing process at least once on the projection so that the diameter of the projection gradually decreases, while the height of the projection remains the same or decreases in a stepwise manner.

The commutator magnet is magnetized so that surfaces having the same polarity face each other between the claw poles and the commutator magnet.

Abstract: A vehicle seat controller includes a feedback controller, a speed instruction value setting unit, and an entrapment determination unit. The feedback controller performs speed feedback control so that a rotation speed of the motor follows a speed instruction value based on a difference of the speed instruction value and an actual speed of the rotation speed of the motor. The speed instruction value setting unit sets the speed instruction value in accordance with a position of the vehicle seat. The entrapment determination unit determines entrapment of a foreign object entrapped by the vehicle seat when the vehicle seat is motor-driven. When the entrapment determination unit makes a foreign object entrapment determination, the speed instruction value setting unit changes the speed instruction value for an entrapment position of the vehicle seat to a low speed value that is smaller than a predetermined initial value.

Radially inner surfaces of the teeth of a stator core face radially outer surfaces of the first and second claw magnetic poles. Either radially outer surfaces of the first and second claw magnetic pole portions or radially inner surfaces of the teeth each have a cross-sectional shape in a direction orthogonal to the axial direction that is not concentric to a circle of which center is an axis of the rotation shaft.
