As shown in the figure, the terminal (4) is attached to the bearing stand (4) that closes the opening at one end for the seal.
The brush metal J=4 (X:) is attached by penetrating the terminal (6), and as shown in the figure, one end of the terminal (6) protrudes from the outer surface of the bearing stand (4) and the bearing stand The brush piece (5) extends from the other end of the terminal (6) that protrudes along the inner surface of (4).
The terminal (5) is arranged so that it extends along the inner surface of the bearing stand (4), and the terminal (5) extends through the bearing stand (4).
The brush metal fitting (3) is fixed by a claw piece tio+ formed in . However, in order to fix it with this claw piece (lO), as shown by 1 in the figure, the thickness of the bearing stand (4) through which the terminal (6) passes is necessary to fix the brush metal fitting oO to the gunfire. Therefore, this thickness (in addition to praise! 1II
A brush piece (5) arranged to protrude into the B pedestal (4)
1] is required for the brush metal fitting (X), and as a result, due to the total length of both, it is limited to thinning the Tanabata, that is, shortening the length along the rotation axis (1) of the 0-Yu. The problem was that .

o) is locked in the protrusion (9). As shown in Fig. 8 and Fig. 4, the housing fi+ is formed into a thin box shape in which the length along the direction of the rotation axis (3) is much shorter than the outer diameter, and the inner outer edge A permanent magnet (11) is attached to the opening at one end, and a bearing stand (4) is attached to the opening at one end in such a way that it almost blocks this opening, and a rotating shaft ( 3) A first bearing a21 that supports one end in a closed manner is formed. An F1 second bearing (1υ) is formed in the center of the other end of the housing fll, and the rotor (2) connects the other end of the rotating shaft (3) to this second bearing.
The housing protrudes outward through the bearing 0η/)[
It can be accommodated within 11. 〇-Yu (2) is an iron core 03 fixed around the rotating shaft (3) [formed by winding a coil round, a coil! A commutator 11b) electrically connected to J41 is formed on the outer periphery of the end of the rotating shaft (3) next to the bearing stand (4). The above bearing stand (4) is! As shown in Fig. I+4 and Fig. 5, a link-shaped synthetic resin molded product was joined to the inner surface of the metal plate, and the metal plate (18
The first bearing (121) described above is housed in the recessed step on the inner surface created by projecting the center outward. The rim of the inner surface of the metal plate 081 is cut out in a manner that surrounds the metal plate 081, and as shown in FIG. This molded product forms a protruding base portion (9) that protrudes from the inner peripheral edge of the bearing base (4).
A recess (8) for storing the brush piece (6) is formed inside the protrusion &ii [91]. On the other hand, the above terminal) fte
As shown in Fig. 6, the + is formed by bending a metal piece into a substantially two-shape shape with tongue pieces (21) extending in opposite directions from both ends of the brush piece (5). One end is connected to one tongue piece 4) in such a way that it fits within the plane containing the terminal (6), and a projecting piece ( 7) protrudes, and a triangular claw piece (io) is formed at the tip of each tongue piece (21). Terminal (6
), as shown in FIG.
Insert the brush piece (6) into the inside of the M cradle (4).
), which is fitted together with the base of the terminal (
6) and the brush piece (6) correspond to the bearing stand (4) in the -radial direction.
), and each brush piece (Ill) can be placed in the recess (
8) Make it protrude towards the center inside. Each slit I24;
A notch @6j is completely formed at a position corresponding to the claw piece 1o+ of the terminal (6), and when each claw piece (1o) is press-fitted into the respective notch part 1, the terminal 941 is inserted into the protrusion part (9). ),
That is, it is fixed to the bearing pedestal (4), and the projecting piece (7) of each terminal (6) passes through the boss (191) and protrudes outward from the bearing pedestal (4). A power source is connected to the projecting piece (19).In addition to the one shown in FIG.
The shape of each axis as shown in Fig. o is used.

オＩＪ点がある。As described above, in the misfire 141, a concave Plr in which the brush piece is accommodated is formed in the center of the inner surface of the bearing base, and the brush piece slides into contact with the rotating shaft within the recess, and the above-mentioned concave is held at the peripheral edge of the inner surface of the bearing base. The terminal is inserted into the surrounding protrusion, and! '1 Since the claw piece formed on the terminal is locked in the protruding part at a position that fits within the plane containing the child piece, the part of the terminal and brush piece other than the protruding piece that protrudes on the outer surface of the bearing stand can be attached to the shaft missing part. This can be accommodated within 11 grooves of the base, and the φ
By being able to connect all the 411 digits on the floor 1" to the middle receiver, it is possible to connect the 411" to the middle receiver.
It is possible to make the tanabata thinner by making sure that the protruding pieces of the illumination are not present. There is an OIJ point where you can hit 1.
