  • Publication number: 20190137017
    Abstract: A pipe joint includes: a sealing member, having an annular shape, which is provided between the outer circumferential surface of a spigot and an inner circumferential surface of a socket; a pushing ring to push the sealing member into the socket, the pushing ring being fitted onto the spigot; and a separation preventive member configured to engage with the spigot protrusion part in a pipe-axial direction to prevent a separation of the spigot from the socket. The separation preventive member is provided between an inner circumferential surface of the pushing ring and the outer circumferential surface of the spigot. The sealing member is provided along an outer circumferential surface of the spigot protrusion part and includes a compression part. The compression part is compressed in a pipe-radial and is located, in the socket, upstream of the spigot protrusion part in an insertion direction in which the spigot is inserted.

  • Patent number: 9889845
    Abstract: A straddled vehicle includes a front wheel, a rear wheel, an engine which generates a driving force and rotates the rear wheel with the driving force, a front wheel brake and a rear wheel brake which lowers the rotation speed of at least the rear wheel, a first detector which acquires and outputs a pitch rate, a second detector which detects and outputs information concerning rotation of the front wheel, and an ECU including a front wheel lift determination circuit which monitors respective outputs from the first detector and the second detector to determine whether a front wheel lift exists based on at least one of the pitch rate and information concerning rotation of the front wheel. When the front wheel lift exists, the ECU controls the driving source or the braking device so that the driving force is lowered or the rotation speed of the rear wheel is lowered.
