Title: ARMATURE AND MANUFACTURING METHOD FOR ARMATURE
Abstract:
Provided are: an armature the manufacture efficiency of which is improved; and a manufacturing method for the armature. In a cross section orthogonal to the central axis C of an annular core 2, a connection projection 22 and a connection recess 32 have shapes which are complementary to each other and become narrower as the distance from coupled surfaces 21, 31 increases. The connection projection 22 and the connection recess 32 have a pair of friction surfaces 23, 24 and a pair of friction surfaces 33, 34 extending in a direction away from the coupled surfaces 21, 31, respectively. The friction surface 23 of the connection projection 22 is inclined with respect to a virtual perpendicular line PL which is perpendicular to a line connecting the base portions of the pair of friction surfaces 23, 24 of the connection projection 22. The friction surface 33 of the connection recess 32 is inclined with respect to a virtual perpendicular line PL which is perpendicular to a line connecting the base portions of the pair of friction surfaces 33, 34 of the connection recess 32.
