Next, the operation of this embodiment will be described.

As shown in FIG. 1, the actuator (C) configured as described above is mounted immediately below the trunk lock device (E) mounted on the vehicle body (D) of the automobile, and the wire (30 ) To the lock release lever (42), and the horizontally pulled out wire (31) to the fuel lid locking device.
The locking rods (43) in (F) are used by connecting them as described above. In this case, the main body of the actuator (C) is vertically long.

When the actuator is not operating, each wire end member (3
0a) and (31a) are located in the inoperative positions shown in FIG. 5, respectively, and the rotating plate (21) has the engaging ends (24) and (25) of both wires as shown in FIG. It is stopped so as to be located between the end members (30a) and (31a) and at an appropriate position to the right of them.

From this state, after energizing the coil (13) of the electromagnetic clutch (12), or at the same time, energize the motor (3) with the rotating shaft.
Energize so that (4) rotates in a predetermined forward rotation direction, for example, a counterclockwise direction in FIG. 5 (hereinafter, when it is referred to as a clockwise direction or a counterclockwise direction, that in FIG. 5). To do.

Then, the armature (16) is attracted to the field core (15), and the armature (16) is fixed to the case (1).

Also, the rotation of the rotating shaft (4) and the sun gear by the operation of the motor (3)
(6) rotates counterclockwise and the planetary gear (8) has internal teeth (10a)
While rotating clockwise along (20a), it revolves counterclockwise around the sun gear (6).

At this time, due to the difference in the number of teeth between the first gear (8a) and the second gear (8b) in the planetary gear (8), the first internal gear (10) is rotated clockwise and the second internal gear (8) is The gear (20) is given a relative rotational force in the counterclockwise direction.

By rotating the first internal gear (10) in the clockwise direction,
As shown in the figure, one bent end (19
A) is pushed counterclockwise by one side edge (11a) of the fan-shaped groove (11).

At this time, the armature (16) is adsorbed by the field core (15) and stopped, and the other bent end portion (19b) of the coil spring (19) is attached to the other side edge () of the arcuate groove (18). Since it is brought into contact with 18b) and stopped, the coil spring (19) gradually expands in diameter inside the tubular body (14) and comes into close contact with the inner surface of the tubular body (14).

Due to the close contact action of the coil spring (19) to the inner surface of the tubular body (14), the bent end portion (19a) of the coil spring (19) is prevented from rotating any more, thereby causing the first internal gear (10) to rotate. ) Clockwise rotation is blocked. After that, all the rotational force of the motor (3) is applied to the second internal gear (20), and the second internal gear (20) is rotated counterclockwise. Since the reduction ratio at this time is extremely large, a small output motor (3)
The second internal gear (20) can be strongly rotated.

With the rotation of the second internal gear (20) in the counterclockwise direction, the rotary plate (21) is rotated in the same direction, and as shown in FIG. After contacting the wire end member (31a), the proximal end portion of the wire (31) is further returned to the return spring (31a) while the wire end member (31a) is still engaged with the engaging end portion (25). The wire winding groove (2
It is wound counterclockwise along 3).

By winding the wire (31) around the rotating plate (21),
(31) is pulled, the lock device (F) is released, and the fuel lid opens.

When the detector (not shown) detects that the fuel lid is opened, and when the coil (13) and the motor (3) are de-energized, the rotating shaft (4) loses its rotational force and the field core (15) is removed. The armature (16) loses its attraction and the armature (16) can rotate freely.

Then, due to the restoring force of the coil spring (19) that attempts to reduce the diameter, the armature (16) moves toward the arcuate groove (18) with respect to the first internal gear (10) as shown in FIG. Each side edge (18a) (18
b) is returned to a position aligned with each side edge (11a) (11b) of the fan-shaped groove (11), and the coil spring (19) itself is slightly reduced in diameter,
The contact with the inner surface of the cylinder (14) disappears, and the cylinder (14) can rotate freely.

Almost at the same time, the wire (31) is pulled rightward by the urging force of a return spring (not shown), and accordingly, the rotary plate (21) is rotated back to the vicinity of the position shown in FIG.

At this time, the rotary plate (21), the second internal gear (20), the planetary gear (8), the sun gear (6), the rotary shaft (4), and the first internal gear (10). ), The armature (16), and the coil spring (19) are united to rotate by a slight angle about the central axis of the rotating shaft (4). At this time, the rotation angle is small, and at this time, the electromagnetic clutch (12) is inactive, and the rotation of the armature (16) is not restrained.
The resistance force at this time is not so large, and the force can be sufficiently restored only by the force of the return spring (not shown).

When it is desired to release the trunk lock device (E), after the coil (13) of the electromagnetic clutch (12) is energized or at the same time, the motor (3) is rotated in the opposite direction to that of the above-mentioned case where the rotary shaft (4) is in the opposite direction. , I.e., energize so as to rotate clockwise.

Then, the rotating plate (21) is rotated in the clockwise direction by the same operation as in the above case only by rotating the gears and the like in the opposite direction, and the engaging end portion (24) of the wire end member ( After abutting against the wire (30a), the wire (30) is wound clockwise along the wire winding groove (23), and the wire (30) is turned into the arc-shaped guide path (3).
Towed along 9), the trunk lock device (E) is released and the trunk opens.

After that, when the detection of the opening of the trunk is detected by a detection device (not shown) and the energization of the electromagnetic clutch (12) and the motor (3) is stopped, the wire (30 ) Is pulled to the right and the wire end member (3
0a) is returned to the position shown in FIG. 5, and accordingly, the rotary plate (21) is slightly rotated counterclockwise.

[Modification]

Although the planetary gear device is used as the speed reducer (A) in the above embodiment, it may be composed of a spur gear train.

〔The invention's effect〕
