Document Type and Number:
Japanese Patent JP4671465
Kind Code:
B2
Abstract:
A structure of shaft member has been developed in which the shaft member is made to be hollow to reduce its weight, installation into a ball bearing or a paper feed roller can be easily carried out and then an appropriate coupling of force can be attained between it and the objective member, wherein the shaft member 1 of the present invention relates to the hollow shaft member of metallic material in which it is fitted to the objective member having holes of bearing 2 and the like therein, its circular sectional plane is divided into three or more outer arcs mi (1,2,3 . . . ) and three or more inverse directed inner arcs ni (1, 2, 3 . . . ) are formed among the outer arcs, the hollow member is inserted into the objective member with the outer arcs and the inner arcs being compressed inwardly and deformed, and the objective member and the shaft member are coupled to each other by a resilient restitution force generated under said compression and deformation in order to satisfy a certain condition.
