A mounting structure in which a cup-like member is secured with enhanced adhesion strength and can be manufactured at reduced cost.
A mounting structure for adhering and securing a bearing housing (3), which is a press-formed closed-bottomed cup-like member, by fitting the bearing housing (3) in a mounting hole (5), wherein the mounting structure is provided with anchoring recesses (7) formed in the adhesion surface on the outer peripheral surface (3a) of the bearing housing (3), each anchoring recess (7) having protrusions (9) therein or having an edged section (11) at the edge of the anchoring recess (7). The interface area of the adhesion surface can be increased by the anchoring recesses (7), and the interface area within each anchoring recess (7) can be increased by the protrusions (9) in the recess (7) or by the edged section (11) at the edge of the recess (7). When solidified, an adhesive agent (13) engages with the protrusions (9) in the recesses (7) or with the edged sections (11) at the edges of the recesses (7).
