PROBLEM TO BE SOLVED: To provide a vibration isolating bush improving an axial spring ratio while suppressing enlargement and increase in the cost. SOLUTION: A main shaft member 1 is provided with a flange part 12 and block parts 14 and 14 axially opposed to each other at some distance apart in the central part of its cylindrical part 11. A rubber elastic body 3 interposed between the main shaft member 1 and an outer cylindrical member 2 is provided with bores 31 and 31 opened in the opposite-side end surface of the flange part and axially extending to the adjacency to the end surface in the side of the flange part 12. The rubber elastic body 3 is provided with a non-deforming rubber parts 32 and 32 positioned between the flange part 12 and the block parts 14 and 14 of the main shaft member 1 and prevented from being deformed by the input of the axial loading, and connecting parts 33 and 33 positioned between the bottoms of the bores 31 and 31 and the end surface in the side of the flange part 12 and connecting the non-deforming rubber parts 32 and 32 to the internal circumferential surface in the end part of the outer cylindrical member 2.
