摘要： The present invention is a vibration damping device (1, 2) that includes an external member (11, 21) attached to one of a vibration-generating portion and a vibration-receiving portion; a tubular member (40) attached to the other of the vibration-generating portion and the vibration-receiving portion; and an elastic body (30) which connects the external member (11, 21) and the tubular member (40). The external member (11, 21) includes a frame-like member (11, 21) having a rectangular shape when viewed from the top. In the elastic body (30), a long-side portion (32a) forming a long side of a rectangular shape when viewed from the top adheres to an inner circumferential surface of the long-side portion (12a, 12b) of the frame-like member (11, 21), and a short-side portion (32b) forming a short side of the rectangular shape when viewed from the top comes into contact with the external member (11, 21) in a long-side direction (X) in which the long-side portion (12a, 12b) extends when viewed from the top, in a non-adhering state.
