The coil connection body has, in a groove provided on a holder, an overhang portion for restricting an axial-direction movement of a terminal, and a positioning projection for restricting a radial-direction movement of the terminal. The positioning projection positions the terminal such that a part of the terminal overlaps the overhang portion in the axial direction. In this structure, when the terminal moves in a direction from a terminal holding portion toward a groove opening, the terminal comes into contact with a side surface of the overhang portion, whereby lifting and coming-off of the terminal can be prevented. ## Claims ### Claim at position 1 1-12. (canceled) ### Claim 13 A rotating electrical machine comprising an annular coil connection body provided coaxially with a stator, wherein the coil connection body includes an insulting holder made of resin and having a plurality of grooves provided coaxially, and a conductive member held in the groove and connected to an end of a coil wound around a tooth of the stator, and each groove has an overhang portion provided at a groove opening side relative to the conductive member on one side wall and restricting an axial-direction movement of the conductive member, and a positioning projection provided at a position opposed in a radial direction to the conductive member on another side wall, and restricting a radial-direction movement of the conductive member. ### Claim 14 (depends on 13) The rotating electrical machine according to claim 13, wherein the positioning projection positions the conductive member such that a part of the conductive member overlaps the overhang portion in an axial direction. ### Claim 15 (depends on 13) The rotating electrical machine according to claim 13, wherein a width dimension in the radial direction of the groove opening is greater than a width dimension in the radial direction of the conductive member. ### Claim 16 (depends on 13) The rotating electrical machine according to claim 13, wherein an interval between most protruding parts in the radial direction of the overhang portion and the positioning projection is smaller than a width dimension in the radial direction of the conductive member. ### Claim 17 (depends on 14) The rotating electrical machine according to claim 14, wherein an interval between most protruding parts in the radial direction of the overhang portion and the positioning projection is smaller than a width dimension in the radial direction of the conductive member. ### Claim 18 (depends on 13) The rotating electrical machine according to claim 13, wherein the overhang portion and the positioning projection are provided over an entire circumference of the groove. ### Claim 19 (depends on 13) The rotating electrical machine according to claim 13, wherein the overhang portion and the positioning projection are partially provided at intervals in a circumferential direction in the groove, and placed so as to overlap each other in the radial direction. ### Claim 20 (depends on 13) The rotating electrical machine according to claim 13, wherein the overhang portion and the positioning projection are partially provided at intervals in a circumferential direction in the groove, and placed so as not to overlap each other in the radial direction. ### Claim 21 (depends on 13) The rotating electrical machine according to claim 13, wherein the other side wall has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 22 (depends on 14) The rotating electrical machine according to claim 14, wherein the other side wall has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 23 (depends on 16) The rotating electrical machine according to claim 16, wherein the other side wall has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 24 (depends on 13) The rotating electrical machine according to claim 13, wherein the overhang portion has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 25 (depends on 14) The rotating electrical machine according to claim 14, wherein the overhang portion has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 26 (depends on 16) The rotating electrical machine according to claim 16, wherein the overhang portion has a slope portion or a curved surface portion for expanding a width of the groove opening. ### Claim 27 (depends on 13) The rotating electrical machine according to claim 13, wherein the positioning projection has a slope portion or a curved surface portion at a corner thereof on the groove opening side. ### Claim 28 (depends on 14) The rotating electrical machine according to claim 14, wherein the positioning projection has a slope portion or a curved surface portion at a corner thereof on the groove opening side. ### Claim 29 (depends on 13) The rotating electrical machine according to claim 13, wherein the conductive member has a slope portion or a curved surface portion at a corner thereof opposed to the positioning projection and a bottom portion of the groove. ### Claim 30 (depends on 14) The rotating electrical machine according to claim 14, wherein the conductive member has a slope portion or a curved surface portion at a corner thereof opposed to the positioning projection and a bottom portion of the groove. ### Claim 31 (depends on 13) The rotating electrical machine according to claim 13, wherein the groove has a through hole in a bottom portion thereof opposed to the overhang portion. ### Claim 32 (depends on 14) The rotating electrical machine according to claim 14, wherein the groove has a through hole in a bottom portion thereof opposed to the overhang portion.
