  • Publication number: 20150211637
    Abstract: A seal structure has one metal gasket arranged between a pair of casings. The metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing. The bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with one casing at this time, whereby any gap in which salt water stays is not formed between one casing and the metal gasket.

  • Patent number: 8388071
    Abstract: A braking controller is equipped to provide braking force distribution of the required total braking force, to distribute the required total braking force by regeneration distribution. The regeneration distribution is required to be within a rear-wheel dominant range, in which the distribution ratio is inclined toward the rear-wheels when compared with an ideal distribution line that provides distribution enabling the front and rear wheels to simultaneously lock, as well as within a range that is not greater than a rear-wheel locking limit enabling the rear wheels to lock in relation to a road-surface friction coefficient upon braking. A rear-wheel braking force change ratio, which is a change ratio of the rear-wheel braking force with regard to a change of the front-wheel braking force associated with the change of the required total braking force, is required to always be positive.
