Abstract:
A cotter-mounting apparatus for mounting a pair of cotters to fix a retainer, which holds a spring to exert a pressing force to an axial member in a compressed state, by causing the pair of cotters to be engaged with engagement grooves formed on the outer circumferential side of the axial member, comprising:a retainer holding mechanism that holds a retainer having a pair of cotters incorporated, and is driven to be relatively elevated and lowered on an upper side in an axial line direction of the axial member; a cotter separating mechanism for separating the pair of cotters from each other over an outer diameter of the axial member roughly in the horizontal direction while pushing up the pair of cotters from downward and for holding the pair of cotters; and a cotter pressing mechanism for pressing the pair of cotters separated by the cotter separating mechanism from an outside roughly in the horizontal direction and causing the pair of cotters to be engaged with the engagement grooves positioned in advance.
