The invention provides a damping apparatus capable of reducing vibration of a workpiece held by a spindle of a processed object. The damping apparatus includes a contact roller (32, 42, 72, 82) provided to be rotatable about a rotation axis, a first support body (31, 41, 71, 81) by which the contact roller (32, 42, 72, 82) is rotatably supported, a second support body (21, 61) holding the first support body (31, 41, 71, 81) so that the rotation axis of the contact roller (32, 42, 72, 82) is parallel to an axis of a spindle, a drive mechanism (50) driving the second support body (21, 61) to bring the contact roller (32, 42, 72, 82) into contact with a workpiece (W) held by the spindle and to separate the contact roller (32, 42, 72, 82) from the workpiece (W), and a base (11) supporting the second support body (21, 61) and the drive mechanism (50). The first support body (31, 41, 71, 81) is held by the second support body (21, 61) via an elastic rubber body. 本发明提供种能够有效地抑制被加工物的振动的制振装置。本发明的制振装置包括：接触滚筒(32、42、72、82
