A joint structure for antiseismic reinforcement includes at least one structural member having a longitudinal axis and at least one antiseismic reinforcement member. Each antiseismic reinforcement member has a longitudinal axis located in a plane that is generally parallel to the longitudinal axis of the structural member. The longitudinal axis of the antiseismic reinforcement member is inclined with respect to the longitudinal axis of the structural member. A metal fitting connects each of the antiseismic reinforcement members to the structural member. The metal fitting is not fixed to the structural member. At least one constraining member is fixed to the structural member close to or abutting an edge portion of the metal fitting. The constraining member bears a force applied to the metal fitting in a direction generally parallel to the longitudinal axis of the structural member.
