The invention provides a joint for a metro anti-side-rolling torsion bar and the metro anti-side-rolling torsion bar. The joint comprises a connecting rod connected to the anti-side-rolling torsion bar, and a pin shaft connected to a vehicle body; a round hole is formed in the end portion of the connecting rod; the middle section of the pin shaft is a bulb which is arranged in the round hole; a polyformaldehyde ball sleeve sleeves the bulb; an axial hold-down leakproof structure is arranged to surround the polyformaldehyde ball sleeve. According to the joint for the metro anti-side-rolling torsion bar, the ball sleeve is made of the polyformaldehyde; the bulb of the pin shaft is in spherical surface contact with the polyformaldehyde ball sleeve during working; the axial hold-down leakproof structure is capable of compensating a gap formed after the polyformaldehyde material is worn down with the bulb of the pin shaft during working; the service life of the joint is long.
