The invention relates to a bearing component of a flow sensor, in particular an impeller, of a domestic appliance, in particular a continuous flow heater. The flow sensor has an axle which is substantially perpendicular to the flow direction of a fluid channel of the domestic appliance in the installed state, and the bearing component is designed as a single part and has two interconnected limbs, each limb having an axle receiving area for one end of the axle of the flow sensor, wherein both axle receiving areas are mutually spaced so as to correspond to the extension of the axle of the flow sensor when the bearing component is unloaded. The two limbs are designed to be elastic such that the spacing between the axle receiving areas can be increased in order to insert the flow sensor between the axle receiving areas.
