Abstract: A floating joint and retainer connection device includes a fixed retainer internally defines a receiving space; an adaptor joint having an end extending through the receiving space to an outer side of the fixed retainer and an axially limiting section formed near another end; a fixing element fitted on the adaptor joint and located outside the fixed retainer for limiting the adaptor joint from moving axially while allowing the adaptor joint to displace radially relative to the fixed retainer; a rolling assembly disposed adjoining the fixed retainer; and a spring located in the receiving space and fitted on the adaptor joint with two ends pressed against the axially limiting section and the fixed retainer or the rolling assembly. When the rolling assembly rolls to displace radially relative to the fixed retainer, a radial frictional force produced by a normal force applied by the spring to the fixed retainer is reduced.
