  • Publication number: 20190160906
    Abstract: A stabilizer includes a stabilizer bar and a rubber bush. The stabilizer bar includes a bar body made of a steel and a coating film covering the bar body. The coating film is formed on the surface of the bar body by using a resin having a water contact angle of more than 65°. By performing surface treatment for reducing the contact angle of the coating film present on an attachment part, the contact angle of the attachment part is changed to 65° or less. A pre-cured liquid adhesive agent is applied to an inner surface (adhesion surface) of the rubber bush. After a region including the attachment part of the stabilizer bar is heated, the rubber bush is overlaid on the attachment part. The adhesive agent is cured in a state where the rubber bush is pressed.

  • Patent number: 10266072
    Abstract: In a power seat operation device, a slider that is supported so as to be slidable in a radial direction with respect to a dial slides toward the radial direction center of the dial during rotation of the dial. A knob engagement portion that is provided to the slider is thereby disposed between a pair of slider engagement portions that are provided to a knob. This enables rotational operation of the knob to be restricted. However, during rotational operation of the knob, one out of the pair of slider engagement portions opposes the knob engagement portion from toward the radial direction center of the dial. This enables rotational operation of the dial in conjunction with sliding of the slider to be restricted.
