Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile parking system for an automobile, and more particularly, to a drive wheel of a vehicle which is driven independently of the operation of a steering system of the automobile so that the vehicle can move at right angles to the traveling direction of the automobile. The present invention relates to a mobile parking device that can be moved laterally and parked at a predetermined position.

[0002]

2. Description of the Related Art Recently, various parking devices have been proposed and put into use so that an automobile can be parked in a limited space. For example, a three-dimensional parking device for vertically moving an automobile in order to expand a parking space is used, and this requires not only an elevating means but also a means for horizontally moving or rotating the automobile, which is relatively large. It becomes a device. On the other hand, various parking devices have been proposed in which horizontal movement or rotation is performed without moving up and down. As a parking device that moves in the horizontal direction, the wheels of the automobile are placed on a trolley, etc., and it is possible to move in the lateral direction at right angles to the traveling direction of the automobile without steering the automobile. It has been proposed that the vehicle can be parked in a parking lot having a slightly longer than the length.

For example, in Japanese Utility Model Publication No. 48-10183,
It is equipped with a pair of rollers that engage with the drive wheels of the automobile, and one of the rollers is driven to rotate by the drive wheels, and the drive force is transmitted to the wheels provided on the trolley so that it is substantially perpendicular to the traveling direction of the automobile. There have been proposed trolleys for moving vehicles that are designed to travel in the direction. Further, Japanese Utility Model Laid-Open No. Sho 53-70587 has a transmission mechanism for transmitting the rotational force of the roller to at least one of the trucks and a roller stopper device for fixing the roller, and the rotational force of the drive wheels of the automobile mounted on the truck. Proposes a moving device for an automobile in which the wheels of the truck are rotated via rollers and a transmission mechanism. The publication is provided with a transmission mechanism for transmitting the rotational force of one roller to the other roller, and both rollers are configured to be rotationally driven by the drive wheels of the automobile. Furthermore,
Japanese Utility Model Unexamined Publication No. 52-86188 discloses an automobile storage trolley having a pair of rollers provided on an underframe, in which a traverse wheel is rotationally driven by drive wheels of the automobile through a power transmission mechanism. The driving force is transmitted from the two rollers to the traverse wheel.

[0004]

In each of the mobile parking apparatuses disclosed in the above publications, in order to transmit the driving force of the driving wheels of the automobile to the wheels of the carriage, both have a roller and a power transmission mechanism, and a part of them is provided. With the exception of the conventional device, a lock mechanism is provided to prevent rotation of the rollers or the wheels of the carriage so that it can escape from the carriage after moving to a predetermined position.

In the mobile parking apparatus having such a lock mechanism, in order to place the drive wheels on the support stand and hold the drive wheels in a stable state in order to park the vehicle, the first and second lock mechanisms are used. It is necessary to release the rotation blocking state for the roller. Further, when the vehicle is to be escaped from the mobile parking device, the lock mechanism must be operated to prevent the rotation of either the first roller or the second roller. Therefore, the driver has to get off the vehicle once to operate the lock mechanism both when the vehicle is parked and when the vehicle is evacuated from the mobile parking device, which is complicated. In particular, during parking, after the vehicle is placed on the mobile parking device, the vehicle can be moved to the parking area as it is without getting off to release the rotation blocking state of the first and second rollers by the lock mechanism. Is desirable.

Therefore, according to the present invention, in the above-described mobile parking device, the support base can be moved in a predetermined direction while supporting the drive wheels on the first and second rollers in a stable state, and the first structure by the lock mechanism is used. It is another object of the present invention to be able to automatically release the rotation blocking state of at least one of the second rollers at least when the drive wheel is mounted on the support base.

[0007]

In order to achieve the above object, a mobile parking apparatus of the present invention includes a support base for rotatably supporting wheels and at least one drive wheel of an automobile mounted thereon.
A first roller and a second roller, which are rotatably supported by the support base at a predetermined distance in parallel to each other and frictionally engage with the drive wheel.
Roller, a rotation transmission mechanism for transmitting the rotational force of the first and second rollers to the wheels, and a side end of the support base that is supported so as to be vertically movable and swingable. And a flap that supports downward movement when the load of the drive wheel is applied, and a rotation of at least one of the first and second rollers that is prevented when the flap moves upward. , A lock mechanism that allows the rotation when the flap moves downward, and a lock mechanism that drives the flap upward to prevent the rotation of at least one of the first and second rollers by the lock mechanism. And a drive wheel other than the drive wheel of the automobile and a driven wheel are movably supported in accordance with the movement of the support base.

Further, in the movable parking apparatus, the lock mechanism has an engaging portion capable of engaging with an outer peripheral surface of at least one of the first and second rollers, and is provided below the flap. A lock plate supported by the support so that the engaging portion moves in a direction away from the outer peripheral surface in response to the movement of the lock plate, and the operating member drives the lock plate upward to drive the lock plate upward. A lever mechanism for engaging the engagement portion with the outer peripheral surface of at least one of the first and second rollers may be provided.

In the lever mechanism, one end is connected to the lock plate, the other end extends to the opposite side of the engaging portion, and the other end side is pivotally supported by the support base, and the lever shaft. With a pedal that drives the lever around
By operating the pedal, the engaging portion of the lock plate can be engaged with the outer peripheral surface of the roller.

[0010]

In the mobile parking apparatus having the above structure, the drive wheels of the automobile are mounted on the first and second rollers by riding on the support base via the flaps. At this time, even if the flap is moved upward and the lock mechanism blocks the rotation of at least one of the first and second rollers, the drive wheel runs on the flap. At this time, the load of the drive wheel is applied to the flap, and the flap moves downward, allowing the rotation of the first and second rollers. That is, the rotation prevention state of the first roller or the second roller by the lock mechanism is automatically released. Then, by rotating the drive wheels of the automobile in this state, the rotational force of the first roller or the second roller is transmitted to the wheels of the support base via the rotation transmission mechanism, and the wheels are rotationally driven. As a result, the automobile moves in a predetermined direction, for example, a direction perpendicular to the traveling direction of the automobile. The other drive wheels and driven wheels of the automobile are mounted on another support base that rotatably supports the wheels, for example.

When the drive wheels are to be escaped from the support base,
If the operating member is operated to drive the flap upward, and the lock mechanism is operated in response to the operation, the rotation of the drive wheel is prevented after the rotation of the first roller or the second roller on the escape side is blocked, Since the driving force is applied to the support stand that is stopped at the predetermined position in the direction of escape, the drive wheels can be easily removed from the support stand. At this time, since the drive wheel rides on the flap, the flap moves downward, and the rotation blocking state for the first or second roller by the lock mechanism is automatically released.

In the case where the lock mechanism having the structure of claim 2 is adopted, for example, when the drive wheel rides on the flap and the flap moves downward, the engaging portion of the lock plate engages the first and the first of the engaging objects. The first and second rollers are allowed to rotate by moving in a direction away from the outer peripheral surface of at least one of the two rollers. On the other hand, when the lever mechanism is operated, the lock plate is driven upward, and the engagement portion thereof engages with the outer peripheral surface of at least one of the first and second rollers to prevent rotation. For example, if the lever mechanism is composed of a lever and a pedal, the lock mechanism can be easily driven by operating the pedal.

However, when the drive wheel DW1 is placed at a predetermined position on the support frame 1, the flap 7a moves As shown in FIG. 8, the free end returns to the state of being separated from the road surface. The other flaps 7b to 7f are similarly supported.

The lock mechanism 70 of this embodiment is shown enlarged in FIG. 3, the assembled state is shown in FIGS. 8 and 9, and the constituent parts are shown in FIGS. In this embodiment, as shown in FIG. 13, a lock plate 71 is provided integrally with the flap 7a, and a hook portion 72 formed at the tip of the lock plate 71 has a groove on the surface of the second roller 20 as shown in FIG. It is configured to engage with and disengage from 20a.
In this embodiment, as shown in FIGS. 3 and 8, the joint plate 84 is fixed to the side surface of the frame member 1c by bolts (not shown). This joint plate 84 is a long plate body as shown in FIG. 10, notches 84c are formed, and support plates 83 are fixed to both sides by welding or the like, and the surface of the joint plate 84 as shown in FIG. To the vertical direction.

The support plate 74 is supported by the joint plate 84 by the bolt 81 via the spring 82 so as to overlap with the joint plate 84. still,
The support plate 74 may be directly supported on the side surface of the frame member 1c. The support plate 74 is an elongated plate body, and as shown in FIG. 11, a pair of elongated holes 74b and a cutout portion 74c are formed, and the above bolt 81 is inserted into the elongated hole 74b, and the support plate 74 is inserted through the cutout portion 74c. The support plate 83 extends and a bolt (not shown) is provided. That is, the support plate 74 is connected to the joint plate 84 by the spring 8
It is pressed and supported by the joining plate 84 by the elastic force of 2, and is supported by the elongated hole 74b so as to be movable in the vertical direction.

A drive plate 73 is fixed to the support plate 74 by welding or the like so as to extend in a direction perpendicular to the surface of the support plate 74. A lock plate 71 is fixed to the opposite surface by welding or the like so as to extend in the vertical direction. The support plate 74 is

Further, a pedal 88 is cantilevered at one end of the shaft 85, and the lever 86 is rotated about the shaft 85 in the counterclockwise direction of FIGS. Is configured.

The operation of the lock mechanism 70 will be described with reference to FIGS. 3 and 8. Normally, the flap 7a is held by the elastic force of the spring 82 so that the tip of the flap 7a has a predetermined gap with respect to the road surface. There is. When the drive wheel DW1 of the automobile rides on the flap 7a, the flap 7a swings around the lower end of the support plate 74 as a fulcrum against the elastic force of the spring 82, and stops when the tip end contacts the road surface. . In this case, if the hook portion 72 of the lock mechanism 70 and the groove 20a on the surface of the second roller 20 are in the engaged state, the support plate 74 side moves downward due to the load applied on the inclined plate 75, Accordingly, the lock plate 71 moves downward and its engagement is released.

Thus, the driver drives the drive wheel DW1 through the flap 7a and the first and second rollers 1 of the support frame 1a.
The lock mechanism 70 is automatically released simply by mounting the lock mechanism 70 on 0, 20. Then, in the state where the drive wheel DW1 is placed on the first and second rollers 10 and 20, the lock mechanism 70
Is in the released state unless the pedal 88 is operated
The rotation of the second rollers 10 and 20 is not hindered.

When the drive wheel DW1 is to be removed from the support frame 1, the lever 8 can be depressed by pushing down the tip of the pedal 88.
6 rotates counterclockwise in FIGS. 3 and 8, the drive plate 73 and the lock plate 71 are driven upward by the pin 86b, move to the position shown by the chain double-dashed line in FIG. 3, and the hook portion 72 moves to the first position. It engages with the groove 20a on the surface of the second roller 20. As a result, the rotation of the second roller 20 is blocked. Therefore, if the drive wheel DW1 is rotationally driven in the direction opposite to the direction in which the drive wheel DW1 enters the support frame 1, the drive wheel DW1 is released from the support frame 1. Become. At this time, the drive wheel DW1 is moved to the flap 7a.
Therefore, the flap 7a moves downward, and the engagement between the hook portion 72 of the lock mechanism 70 and the groove 20a of the second roller 20 is automatically released.

As described above, the lock mechanism 70 is driven by the operation of the pedal 88, and the rotation blocking state for the second roller 20 is automatically released by the downward movement of the flap 7a. , The vehicle can be easily moved to a predetermined parking area. The lock mechanism 70 of the present embodiment is configured such that the hook portion 72 of the lock plate 71 is engaged with the groove 20a on the surface of the second roller 20, but a disc is separately provided on the shaft of the second roller 20. Provided,
A mechanism may be used in which the hook portion 72 is engaged with and locked to a groove formed on the outer peripheral end surface.

The operation when the front wheel drive vehicle (not shown) is parked at a predetermined position using the mobile parking apparatus of the present embodiment having the above-mentioned structure will be described. In FIG. 2, the front drive wheel DW is shown.
1 and DW2 ride on the support frames 1 and 2, respectively,
The vehicle is operated so that the driven wheels FW1 and FW2 ride on the support frames 3 and 4, respectively. At this time, drive wheel DW
Since the vehicle 1 rides on the flap 7a, even if the flap 7a is in the upper position, the lock mechanism 70 shown in FIG.
Lock plate 71 moves downward together with the support plate 74 (moves from the two-dot chain line in FIG. 3 to the solid line), and the hook portion 72 and the groove 20a of the second roller 20 are automatically engaged. It will be canceled. In this state, drive wheels DW1, DW
When 2 is rotationally driven, the drive wheel DW2 does not rotate due to frictional engagement with the rods 10r and 20r of the support frame body 2,
The first and second rollers 10 and 20 of the support frame 1 rotate as follows according to the rotation of the drive wheel DW1.

For example, when the drive wheel DW1 is rotationally driven in the direction in which the vehicle is moved forward as it is, that is, when the drive wheel DW1 is rotationally driven clockwise when viewed from the lower side of FIGS. The rollers 10 and 20 are rotationally driven by frictional force, the shaft 11 rotates counterclockwise, and the shaft 21 rotates counterclockwise. At this time,
The shaft 21 is engaged with the bevel gear 42 via the second one-way clutch mechanism 32, and the rotating force of the shaft 21 causes the bevel gear 4 to rotate.
It is transmitted to 2 and rotates counterclockwise. This torque is
It is transmitted to the wheels 61 and 62 via the bevel gear 52 and the spur gears 53 to 56 shown in FIG. 4, and the wheels 61 and 62 rotate. On the other hand, on the first roller 10 side, the engagement between the outer cylindrical body 31a and the inner cylindrical body 31b of the first one-way clutch mechanism 31 is released, and the first roller 10 is in the idling state.

Then, for example, when the movement of the support frame 1 is blocked by an obstacle or the like while the drive wheel DW1 is rotating,
As the wheels 61 and 62 decelerate and stop, the first and second bevel gears 41 and 42 also decelerate and stop. Therefore, while the second roller 20 cannot rotate, the drive wheel DW1
Since it continues to rotate, it kicks the second roller 20 to move in the traveling direction of the vehicle, that is, to the right in FIG. 4, and rides on only the first roller 10. However, with the counterclockwise rotation of the first roller 10 at this time, the shaft 11 that is in a rotating state and the bevel gear 4 that is in a decelerating or stopped state.
Due to the relationship with 1, the outer cylinder body 31a and the inner cylinder body 31b in the first one-way clutch mechanism 31 do not engage with each other, and thus the first roller 10 idles. in this way,
Since the first roller 10 on the traveling direction side idles, the drive wheel DW1 does not ride over the first roller 10 and jump out in the traveling direction.

Further, when the braking device of the automobile is operated to stop the rotation of the drive wheel DW1, the inertial force applied to the support frame 1 gives a rotational force to the wheels 61 and 62 in a direction in which the wheels continue to rotate, While the rotational force is transmitted to the bevel gears 41 and 42, the shafts 11 and 21 are in a state of deceleration to stop, and the relationship between the two is opposite to the above-described driving time. That is, the inertial force of the support frame 1 is the wheel 6
1, 62 to spur gears 56, 55, 54, 53, bevel gears 5
1, 52 are transmitted to the bevel gears 41, 42, but the rotation of the first and second rollers 10, 20 is blocked by the braking force of the vehicle. Therefore, the first and second one-way clutch mechanisms 31 , 32, the relationship between the relative velocities of the outer cylinder and the inner cylinder is reversed. Therefore, while the second roller 20 is in the idling state, the braking force applied to the first roller 10 is transmitted to the wheels 61 and 62 as a negative rotational force, and finally the support frame 1 is It will be stopped.

As described above, when the support frame 1 is prevented from moving and the wheels 61 and 62 decelerate and stop, the drive wheel DW is used.
When 1 is rotationally driven, the first roller 10 on the traveling direction side of the vehicle runs idle. On the other hand, the wheels 61, 6
When decelerating and stopping the drive wheel DW1 while 2 is rotating,
The braking force applied to the first roller 10 is transmitted as a negative rotation force to the wheels 61 and 62 that continue to rotate due to inertia, and the support frame 1 is stopped. Then, the mobile parking device moves in the direction of the white arrow Pa (the direction perpendicular to the traveling direction of the vehicle) in FIG. 2 with the vehicle mounted, and operates the vehicle braking device to rotate the drive wheel DW1. By stopping, it is possible to stop at a predetermined position in a stable state.

Since the drive wheel DW2 on the other side is generally connected to the drive wheel DW1 via a differential gear (not shown), it is driven when both the drive wheels DW1 and DW2 are rotationally driven. When the wheel DW2 idles, the load on the drive wheel DW1 side interlocking with the wheels 61 and 62 becomes larger than that on the drive wheel DW2 side, and the support frame 1 cannot be moved by the drive wheel DW1. Therefore, as described above, the rods 10r, 20 fixed to the support frame 2 are prevented so that the drive wheels DW2 do not idle.
It is supported by r. Therefore, both drive wheels DW1, DW2
When the mobile parking device is configured to be driven by, the support frame 2 may be provided with the same mechanism as the drive wheel DW1 side.

In order to return the vehicle from the parking area to the original position, the drive wheel DW1 is driven to rotate in the opposite direction to the above-mentioned movement, so that the vehicle moves in the direction of the outline arrow Pb in FIG. In either case, if the vehicle braking device is operated, the drive wheel DW1
Since the rotation of the car stops and the mobile parking device also stops,
The lateral movement of the mobile parking device can be controlled by the same operation as the driving operation when the vehicle moves forward and backward.

When the vehicle is to be removed from the supporting frames 1 to 4, the pedal 88 is operated to drive the lock plate 71 of the lock mechanism 70 (from the state shown by the solid line in FIG. 3 to the state shown by the chain double-dashed line). When the tip of the hook portion 72 is engaged with the groove 20a on the surface of the second roller 20, the second roller 20 is locked and the drive wheel DW is moved.
By rotationally driving 1 and DW2 in opposite directions, the vehicle can be ejected in a direction opposite to the approach direction to the support frames 1 to 4.

As described above, in the mobile parking apparatus of this embodiment, when the drive wheel DW1 rotates clockwise when viewed from below in FIGS. 1 and 4, the rotational force of the drive wheel DW1 is the second roller. While being transmitted to the wheels 61 and 62 via 20, the first roller 10 runs idle. Conversely, drive wheel D
When W1 rotates counterclockwise as viewed from below in FIGS. 1 and 4, the rotational force is transmitted to the wheels 61 and 62 via the first roller 10, but the second roller 20 idles. To do. That is, drive wheel DW1
When is driven to rotate, the rotational force is transmitted to the roller on the front side, and the other roller (which is on the backward traveling direction side of the automobile) runs idle.

Therefore, even if the drive wheel DW1 is rotationally driven in a state in which the movement of the support frame 1 is blocked, the roller located on the traveling direction side of the vehicle runs idle, so that the drive wheel DW is driven.
1 does not separate from the support frame 1, and there is no risk of the automobile jumping out in the traveling direction. That is, the roller to which the rotational force is transmitted is the first and second one-way clutch mechanism 3
1, 32 the direction of rotation of the drive wheel DW1 and the wheel 6
Since the shaft 11 or 21 of the first or second roller 10 or 20, which is the traveling direction side of the automobile, idles, it is automatically selected in accordance with the relative speed with respect to 1, 62.
There is no risk of popping out due to incorrect operation of the car. In addition, as shown by a two-dot chain line in FIG.
Blocks 1k and 2k for stoppers may be provided on the side of the first roller 10 and the rod 10r.

Rotational drive direction of drive wheel DW1 and support frame 1
When setting the relationship with the moving direction of No. 1 to the relationship opposite to the above-described embodiment, the sub-assembly consisting of the bevel gears 51 and 52, the spur gear 53, the shaft 57 and the bearing of FIG.
The sub assy of FIG. Further, if the support frames 1 to 4 and the connecting mechanism 9 are made detachable, they can be stored separately and assembled when necessary. Alternatively, the support frame 1 may be attached to the driven wheel FW.
A long plate body including the supporting frame body 3 for 1 may be used, and an opening may be formed so that the first and second rollers 10 and 20 are exposed. Further, all the support frame bodies including the support frame bodies 2 and 4 may be formed as a single plate body, and all the components may be mounted on the plate body.

In this embodiment, the wheels 61 and the like provided on the support frames 1 to 4 are both the first and second rollers 1.
Although the support frames 1 to 4 are configured to move in a lateral direction at right angles to the traveling direction of the automobile by rotating around axes perpendicular to the rotation axes of 0 and 20, they support wheels 61 and the like. If it is configured to rotate about an axis deviated by a predetermined angle with respect to the frames 1 to 4, it can be moved in a direction oblique to the traveling direction of the automobile.

FIGS. 15 and 16 show another embodiment of the lock mechanism 70. In the above embodiment, the lock plate 71 is fixed to the support plate 74, whereas in this embodiment, the lock mechanism is locked. The plate 171 is supported by the drive plate 173 so as to be rotatable around a shaft 175. Like the drive plate 73 described above, the drive plate 173 is fixed to the support plate 174, but the support plate 174 has a holding plate 174a extending in the horizontal direction. It is configured to restrict the clockwise rotation.
The holding plate 174a may be formed separately from the support plate 174 instead of being integrally formed, and may be joined later. Further, the positional relationship between the drive plate 173 and the lever 86 is different from that in FIG. 3, but of course the positional relationship similar to that in FIG.

Further, a spring 176 is arranged between the intermediate portion of the lock plate 171 and the frame member 1c, and the lock plate 171 is biased to rotate counterclockwise about the shaft 175. Therefore, the lock plate 17
In the free state, No. 1 is held in contact with a holding plate 174a as shown in FIG. 16 (shown by a chain double-dashed line in FIG. 15). In addition, instead of the spring 176, the shaft 1
A spring may be provided at 75 to urge the lock plate 171, or another urging means may be provided. Other configurations are the same as those of the lock mechanism 70 and the like in the above-described embodiment, and therefore, the same reference numerals are given and description thereof is omitted.

According to this embodiment, when the flap 7a is located below, the hook portion 172 of the lock plate 171 is in the second position as shown in FIG. 16 as in the embodiment of FIG.
Is not engaged with the groove 20a of the roller 20 of FIG.
8 is pushed down and the support plate 17 is moved by the lever 86.
When 4 is pushed up, it will be in the state shown in FIG.
At this time, for example, when the lock plate 171 is positioned as shown by the solid line in FIG. 15, the hook portion 172 causes the second roller 2 to move.
0 groove 20a is not engaged. In such a case, in the above-described embodiment shown in FIG. 3, the hook portion 72 has the second roller 20.
Even if the pedal 88 comes into contact with the outer peripheral surface thereof, a load change occurs in the pedal 88. As a result, the driver can
If the pushing down operation is stopped, the support plate 74 may stop at that position, and the hook portion 72 may remain disengaged from the groove 20a.

On the other hand, in this embodiment, if the pedal 88 is pushed down with a force equal to or greater than the predetermined value, the support plate 174 is joined to the joining plate 84 even after the hook 172 contacts the outer peripheral surface of the second roller 20. 15, the lock plate 171 rotates clockwise around the shaft 175 against the urging force of the spring 176 and tilts downward as shown by the solid line in FIG. Held in a state. When the second roller 20 is driven to rotate slightly in this state and the positional relationship between the hook portion 172 and the groove 20a is deviated, the hook portion 172 is immediately broken by the two-dot chain line by the urging force of the spring 176. As shown, it will engage with the groove 20a.

FIG. 17 shows still another embodiment of the lock mechanism 70, showing the flap 7a in the upper position. In the embodiment of FIG. 3 described above, the hook portion 7
2 engages the groove 20a so that the second roller 20
In the present embodiment, a wedge portion 272 is formed as an engaging portion at the tip of the lock plate 271, and the wedge portion 272 is connected to the frame member 1c and the second member.
The second roller 20 is prevented from rotating due to a so-called wedge effect when the second roller 20 comes into contact with the roller 20 and comes into contact with the outer surfaces of the both rollers. Therefore, in this embodiment, it is not always necessary to form the groove 20a on the outer peripheral surface of the second roller 20. In this embodiment also, as shown in FIG. 17, the lock plates 2 are provided on both sides of the support plate 274, respectively.
71 and the drive plate 273 are fixed. Other configurations are similar to those of the above-described embodiment, and therefore, the same reference numerals are given and the description thereof is omitted.

In each of the above embodiments of the lock mechanism, it is necessary to push down the pedal 88. Therefore, when the vehicle is to be evacuated from the mobile parking apparatus, the driver must get off and press the pedal 88. It must be complicated. Therefore, in the embodiment shown in FIGS. 18 and 19, the handle 89 is connected to the pedal 88 via the wire WR.

That is, in FIG. 18, the pedal 88 of the lock mechanism 70 having the same structure as that of FIG. 3 is formed with an extending portion 88a extending toward the opposite side of the pressing portion from the shaft 85, In addition to this, for example, piano wire WR
Is fixed at its base end, and a handle 89 is fixed at its tip. Thus, the driver can drive the lock mechanism 70 by simply pulling the handle 89 from the window in the direction of the white arrow in FIG. 18 while riding in the automobile, so that better operability can be obtained. Moreover, since the wire WR has flexibility, there is no risk of damaging it even if it comes into contact with the automobile during movement.

However, in the embodiment shown in FIG. 18, when the handle 89 is pulled and then released, the wire WR is moved to the position shown in FIG.
As shown by the two-dot chain line in FIG. 8, the shape is extended in a substantially horizontal direction, and an unstable supporting state is obtained. Therefore, in the embodiment shown in FIG. 19, the pedal 88 is connected to the link mechanism 188, and the link mechanism 188 is connected to the wire WR. That is, one end of the link L1 is fixed to the shaft 85 together with the pedal 88, and the other end of the link L1 is rotatably supported by one end of the link L2. The other end of the link L2 is rotatably supported by one end of the link L3, and the other end of the link L3 is rotatably supported by the support frame 1.
Thus, a four-bar rotary chain is formed, and in this embodiment, a parallel crank mechanism in which opposing links have the same length is formed. The base end of the wire WR is fixed in the middle of the link L2.

Thus, according to this embodiment, the driver not only can drive the lock mechanism 70 by pulling up the handle 89 in the direction of the white arrow in FIG. In this operation, the handle 89 only moves substantially linearly as shown by the chain double-dashed line in FIG. 19, so that the driver can operate it very easily.
