PURPOSE:To enable a vibration proofing effect against input vibration in the axial direction to be effectively exhibited, and concurrently form a bottle neck passage which can prevent the occurrence of a high dynamic spring motion when vibration is inputted in the direction orthogonal to the axis in the main liquid chamber of the fluid sealing type mount. CONSTITUTION:A step section 56 is provided at the outer circumferential wall section of a main liquid chamber 54, an inner projection 57 in a ring shape which is projected toward the direction orthogonal to the axis from the side of an outer member 14, is formed at the bottom section side of the main liquid chamber 54, and concurrently an inner member 12 is inserted in the inner projection 57 so as to be positioned therein, so that a bottle neck passage 58 in a ring shape is thereby formed between the surface of the inner member 12 and the surface of the inner projection 57, which are opposite to each other in the direction orthogonal to the axis. |
