G.Resin P1 flows into the inner side of annular component R from this cast gate G.The resin P1 flowing into is formed rectifier main part 81.Then, will
The annular component R being formed with rectifier main part 81 takes out from stationary fixture 111.Further, the cylindric rectification of annular component R
Piece portion P1 is machined and forms the multiple commutator segments 82 separating with equidistant from distance.
(protuberance formation process)
As shown in figure 12, in the rectifier 8 before the processing of protuberance formation process, riser 83 is from one end of commutator segment 82
It is at right angles radially oriented outside as the crow flies to extend.Additionally, in protuberance formation process, use and there is cylindric the of bottom
One stationary fixture the 101st, columned second stationary fixture 102 and the first moveable jaw 103, wherein, above-mentioned first moveable jaw
The inner circumferential of 103 and the periphery of the second stationary fixture 102 are chimeric in the way of can freely moving along a straight line.Here, fix first
The peripheral part of the open end of fixture 101 is provided with concave relief portion 101a.
In protuberance formation process, first, rectifier 8 is inserted in the cylinder of the first stationary fixture 101, so that riser
On 83 open ends being maintained at the first stationary fixture 101.Then, above-mentioned open end and the second stationary fixture 102 are utilized, right
The cardinal extremity part of riser 83 clamps and fixes.Then, make the first moveable jaw 103 towards the direction of arrow (relief portion of Figure 12
The direction of 101a) linear motion.By above-mentioned linear motion (extruding), make the master relative to riser 83 for the fore-end of riser 83
Body, prominent in the way of there is step towards relief portion 101a direction.Utilizing makes said front part in the way of having step
Prominent, and form protuberance (locking element) 83a in the leading section of riser 83.
(bending operation)
As shown in figure 13, in the rectifier 8 before the processing of bending operation, the leading section of riser 83 is formed prominent
Portion's (locking element) 83a.On the other hand, riser 83 is at right angles radially oriented outside extension as the crow flies from one end of commutator segment 82.
Here, in bending operation, use and there is the 3rd cylindric stationary fixture of bottom the 104th, there is cylindric the of bottom
Four stationary fixtures the 105th, columned 5th stationary fixture 106 and the second circular moveable jaw 107, wherein, the above-mentioned 4th
Stationary fixture 105 configures in the 3rd stationary fixture 104, and rectifier 8 can be made to insert inside it, above-mentioned 5th stationary fixture

Inner circumferential surface is guided by the outer peripheral face of the 5th stationary fixture 106, thus is set to and can transport along the free straight line of the direction of arrow of Figure 13
Dynamic.Additionally, moved along a straight line along the direction of arrow shown in Figure 13 by making the second moveable jaw 107, riser 83 is just towards commutator segment 82
The other end bend to hook-shaped.Then, by above each operation, the rectifier 8 of present embodiment can just be formed.
(effect that present embodiment is had)
Rectifier 8 includes prominent for hinder the winding wire W being wound on riser 83 leading section to depart from from the front end of riser 83
Go out portion's (locking element) 83a.Riser 83 is made to be pressed into commutator segment by the second electrode bar 202 when being processed by the welding shown in Figure 14
When 82, above-mentioned protuberance (locking element) 83a can be utilized to be effectively prevented winding wire W and to depart from from the front end of riser 83.Therefore,
As shown in figure 15, riser 83 can be formed shorter, and riser 83 institute on commutator segment 82 after welding processing can be shortened
The axial length accounting for.Thereby, the part occupied by riser 83 in the axial length of commutator segment 82 can be made to reduce.
Accordingly, it is capable to guarantee the axial length of brush 3c sliding contact on commutator segment 82 fully.In addition, can be by rectification
The axial length of the axial length of piece 82 and the rectifier main part 81 for fixing commutator segment 82 forms shorter.Its result
It is possible to realize the miniaturization of rectifier 8.Even if in addition, thicker in the line footpath of winding wire W in the case of, above-mentioned by arranging
Protuberance (locking element) 83a, it is also possible in the case of riser 83 not being formed longer, effectively hinder be wound on perpendicular
Winding wire W on plate 83 departs from from the front end of riser 83.
Protuberance 83a is configured to highlight integratedly in the way of having step from the front end of riser 83 towards commutator segment 82.
So, owing to protuberance 83a being configured to highlight integratedly from riser 83, therefore, it is possible to do not installing other on riser 83
In the case of parts, by self being processed to riser 83 form protuberance 83a, so that material and cost reduce.
In addition, protuberance 83a is only just plastic by linear motion (extruding) operation of protuberance formation process.Therefore,
Protuberance 83a can be molded with easy manufacture method.
