Abstract:
A liquid filled vibration isolator comprising:a cylindrical member made of a metal material;an inward-bent part slightly extending to one end side of said cylindrical member inwardly in a radial direction;a thin rubber member coated part provided on an inner peripheral surface of the cylindrical member, said rubber member coated part having an inner diameter equal to or smaller than an inner diameter of said inward-bent part;a bottom wall member inserted into from one end side of said cylindrical member and mounted on an inner peripheral surface of said rubber member coated part to close thereby an opening portion on the one side thereof;a rubber member subjected to vulcanization and bonding and a fitting member fixed to said rubber member provided on the other end side of said cylindrical member to close thereby an opening portion on the other end side thereof; anda liquid chamber for vibration isolation thereby formed inside the cylindrical member, whereinsaid inward-bent part is formed on said cylindrical member in advance prior to providing said thin rubber member coated part on the inner peripheral surface of the cylindrical member, andafter said bottom wall member is inserted into the inner peripheral surface of said thin rubber member coated part, the inner diameter of said inward-bent part is made smaller than the outer diameter of said bottom wall member by pressing the cylindrical portion of said cylindrical member inwardly in a radial direction thereof to reduce the diameter of the cylindrical portion.
