An outer sleeveless type resilient bush wherein a resilient body fixed to the outer circumference of an inner sleeve is brought into contact with the inside face of a support hole of an article to be supported, an inserted sleeve being embedded in the resilient body, axial notches and split grooves are respectively formed on the inserted sleeve and the resilient body. flanges that bend in the diametrically outwards direction are formed at both ends of the inserted sleeve, and arranged to extend outwards in the diametrically outwards direction and the flange at one end is made capable of reduction in diameter, so that the resilient bush can be inserted into the support hole from the side of this flange, and resistance to withdrawal from the support hole can be increased and performance is improved by making the initial compression ratio of the resilient body large.
