PURPOSE: To provide 2 flexible joint for tilted piping to be used for fluid containing dust, with which erosion of a bellows is reduced, and no particle is accumulated on the part of the bellows even when the flow velocity is changed.

CONSTITUTION: A flexible joint for tilted piping is provided with a connection part 11 having the same inner diameter (d) as that of a piping to be connected, an upper hollow member 13 and a lower hollow member 14 having extended diameter parts 12 having an inner diameter D larger than an inner diameter (d), at least one hollow cylindrical flexible bellows 15, the both end of which are connected to the extended diameter parts of the upper hollow member and the lower hollow member, and a hollow cylindrical first liner 17, with which the inner surface of the bellows is covered at an interval in the radial direction, and the lower end of which is connected to the lower end part of the bellows. A hollow cylindrical second liner 18 is also provided, which has the same inner diameter as that of the piping to be connected, with which the inner surface of the first liner is covered at an interval in the diameter direction, and the upper end of which is connected to the upper end part of the bellows.
