摘要： It is an object of the present invention to ensure that a torque rod breaks downward when a predetermined load or greater is input thereto. A torque rod has a first annular portion (21), a second annular portion (22), a connecting stay portion (24) that interconnects the first annular portion (21) and the second annular portion (22), a first attachment member (31) that is connected via a first rubber elastic body (41) inside the first annular portion (21), and a second attachment member (32) that is connected via a second rubber elastic body (42) inside the second annular portion (22). The connecting stay portion (24) has an upper fork portion (24U) and a lower fork portion (24L), and the bending strength of the lower fork portion (24L) is less than that of the upper fork portion (24U). A cavity portion (30) to which part of the first annular portion (21) is exposed is formed between the upper fork portion (24U) and the lower fork portion (24L). A thin-walled portion (21A) having a projecting portion (21B) is disposed in a region of the first annular portion (21) exposed to the cavity portion (30). A sloping surface (24A) whose lower side slopes toward the second annular portion (22) is formed in a region of the cavity portion (30) opposing the first annular portion (21).
