  • Patent number: 10807454
    Abstract: A stopper portion includes a first protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction; and a second protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction, being spaced apart from the first protruding portion so as to be in a non-contact state with the first protruding portion, being thinner than the first protruding portion in the main load input direction, and having a protruding end in which a distance between the protruding end and the contact surface is longer in the main load input direction than a distance between a protruding end of the first protruding portion and the contact surface.
