[2] Structure of Wire Winding Device As shown in FIGS. 1 and 2, the wire winding device 20 includes a resin casing 25 and a resin winding drum 21 housed therein. Composed of and.

The casing 25 has a substantially cap shape (note that the back surface of the top plate 251 is drawn upward in FIG. 1), and the casing 25 is provided at the lower portion (upper position in FIG. 1) of the peripheral wall 252. −
Thing 25 is attached to pawl 353 (Fig. 4) on the upper outer wall 35 of the motor housing.
(Refer to FIG. 3), mounting portions 253 having mounting holes 253a for one-touch fitting are provided at a total of three positions so as to form an angle of 120 ° with each other.

Further, in the tangential direction of the peripheral wall 252, the opening 25
A wire guide portion 254 is provided so that the angle 4a is directed to the pulleys 15 and 16 (FIG. 5). The wire guide portion 254 has the same function as the conventional end fixture 202 shown in FIG. That is, the tips of the outer cables 11a and 12a covering the wires 11 and 12 are received by the inner wall surface that narrows in a taper shape from the opening 254a toward the inside, and the outer cable is bonded and fixed to the inner wall surface. The tips of the wires 11 and 12 extending from inside the bulls 11a and 12a are introduced so as to be connected to the winding drum 21. 254b is a notch groove for inserting the wires 11 and 12 at the time of assembling.

Further, at the center of the back surface of the top plate 251, a locking pin 255 consisting of three divided parts is erected. The locking pin 255 is inserted into a locking pin receiving hole 215 (see FIG. 4) on the back surface of the winding drum 21 to fix the winding drum 21 to the case.
It is fixed inside the peripheral wall 252 of the thing 25. Therefore, the locking pin 255 is divided into three parts so that the outer diameter of the arrow portion 255a at the tip thereof can be contracted when inserted. Also, Yabe 255a
The rear surface of is formed as a locking surface 255b so as to be locked to the locking surface 215b of the expanded portion 215c inside the locking pin receiving hole 215 (described later) of the winding drum 21. In addition, the above-mentioned spread part
215c is a space for allowing the winding drum 21 to freely rotate from the locking pin 255.

On the other hand, the winding drum 21 is a member having a substantially cylindrical shape, and the wires 11 and 12 introduced from the wire guide portion 254 of the casing 25 are wound on the circumferential surface of the cylinder in opposite directions. After being turned, its tip is fixed.

The front surface of the winding drum 21 (the front side when viewed from the outside when set on the vehicle body, that is, the top plate 251 of the casing 25)
The side facing the back of is called the front here. It is hidden in FIG. It is the upper surface of FIG. ) Has a locking pin receiving hole 215 formed in the center thereof.
As described above, the expanded portion 215c is formed in the inside of the. In addition, due to the expanded portion 215c, the arrow portion of the locking pin 255
A locking surface 215b corresponding to the back surface 255b of the 255a is formed.

A rotary bearing hole 217 for receiving the rotary shaft 357 of the drive mechanism 30 is formed in the center of the rear surface (upper surface in FIG. 1) of the winding drum 21 to rotate the motor 301. It can be rotated correspondingly.

[3] Assembly of Wire Winding Device The wire winding device 20 having the above-described structure is attached to the motor housing of the drive mechanism 30 as shown in FIG. First, the wires 11 and 12 are wound around the circumferential surface of the winding drum 21 in opposite directions, and the tips thereof are locked to locking portions (not shown) inside the winding drum 21.

Next, the winding drum 21 is housed in the peripheral wall 252 of the casing. As a result, the locking pin 255 of the casing is inserted into the locking pin receiving hole 215 of the winding drum 21, and the both are integrated. In addition, the wires 11 and 12 are notched in the groove 254b.
To the wire guide section 254. At this time, the tension from the wires 11 and 12 exerts a force to incline the winding drum 21, which is caused by the protrusion 254c formed so as to project inside the wire guide portion 254. To be prevented.

In this way, after the winding drum 21 is integrated with the casing 25, the rotary bearing hole 21 in the center of the rear surface of the winding drum 21 is formed.
Insert the rotary shaft 357 of the drive mechanism 30 into the
The mounting hole 253a of the mounting portion 253 below the peripheral wall 252 of the single 25 is
Insert it into the claw 353 of the upper outer wall 35 of the motor housing with one touch. As a result, the wire winding device 20 is assembled to the drive mechanism 30.

[0022]

As described above, according to the present invention, after the winding drum is mounted on the casing formed by integrally forming the wire guide portion and the lid portion, the winding drum is assembled to the motor housing. .. Therefore, the number of parts is small and the manufacturing process is simplified. In addition, since the work of attaching the winding device to the drive mechanism can be performed with one touch, the assembly at the time of manufacture and the disassembly / assembly at the time of repair are easy.
Further, there is an effect that the drive mechanism and the winding device can be separately supplied.
