This vibration isolating apparatus (1) includes a cylindrical first mounting component (6), a second mounting component (7), a rubber elastic body (8), a diaphragm (5), and a partitioning component (4). The partitioning component (4) is formed entirely from an elastic body, and on the first mounting component (6) there are provided a protruding portion (60) and a first cylindrical portion (62), and a toroidal rigid component (50) is fitted on an inner side of the first cylindrical portion (62), and in the rigid component (50) there are provided a second cylindrical portion (53) and a supporting portion (54). Moreover, any one of the first and second cylindrical portions (62, 53) is located inside the other one of the first and second cylindrical portions (52, 63), and in the component (6) that is provided with the other cylindrical portion (62) there are formed an engaging portion (60) which engages with one end portion of the one cylindrical portion (53), and a caulked portion (64) which is folded inwards in a radial direction and which engages with the other end portion of the one cylindrical portion (53). The one cylindrical portion (53) is sandwiched between the engaging portion (60) and the caulked portion (64), and the partitioning component (4) is sandwiched between the protruding portion (60) and the supporting portion (54). According to this vibration isolating apparatus (1), even if a partitioning component made from an elastic body is used, it is possible to secure seal property and obtain stable characteristics. |
