Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle anti-theft device and a motorcycle anti-theft device provided on a handle grip of a motorcycle such as a scooter.

[0002]

2. Description of the Related Art Conventionally, motorcycles have been provided with a handle lock mechanism for fixing the left and right movements of the steering wheel and the front wheel with the steering wheel fully turned left or both left and right. Locking and unlocking operations can be performed on the main key portion of almost all vehicle models. Because it is a mechanism that can be easily locked,
At present, almost all motorcycles that are parked are locked with this handle lock.

Incidentally, it can be said that such a bicycle parking state is closer to an unprotected state than a four-wheeled vehicle. That is, in a four-wheeled vehicle, even if someone tries to steal, neither the main key nor the control device can be touched at all without first entering the inside of the vehicle. As shown in FIG.
The main key switch 2 also functions as a handle lock lock even when the handle is locked (see FIG. 7B).
Is exposed to the outside and can be freely touched, including other control devices, so even if someone is touching the motorcycle 1, it is possible to ask a third party whether they are trying to steal or not. I do not know at all.

[0004] Specifically, as shown in FIG.
The handle operation section 3 has a front car 4 on the front side and a pocket storage space 5 on the rear side.
The main key switch 2 is provided above the pocket storage case 5. On the right side of the handle operation unit 3, a handle grip unit 6R (accelerator grip) and a front brake lever 7, which can perform an accelerator operation by rotating the grip, are provided, and an engine start cell switch 8 is provided near the center thereof. Have been. On the other hand, a handle grip 6L and a rear brake lever 10 are provided on the left side of the handle operation unit 3, and a headlight low / high switch 11, a turn signal switch 12, and a horn switch 13 are provided near the center thereof. I have. Further, a right rear-view mirror 14 and a left rear-view mirror 15 are provided at the center of the both handle grips 6R and 6L, and a meter panel 16 is provided at the center. Thus, in general, in a motorcycle,
All the control devices including the main key switch 2 can be freely touched.

[0005] Therefore, a person who wants to steal the motorcycle should destroy the main key switch 2 using a hammer, a driver, or the like, unlock the handle lock, and turn the main key switch 2 to the ON position. Since it is possible to drive a motorcycle freely and to be able to escape, a great number of motorcycles, especially scooters, have been stolen all over the country.

Therefore, as a device for preventing theft, an antitheft device generally called a U-shaped lock is very widely used. As shown in FIG.
Reference numeral 01 is used by being attached to the rear wheel 1a or the front wheel of the two-wheeled vehicle 1, and makes traveling impossible. In addition, the two-wheeled vehicle 1
When parking a bicycle, the bicycle is generally housed in the bicycle parking space from the front wheel side. Therefore, in most cases, the bicycle is mounted on the rear wheel 1a.

The U-shaped lock 101 has a high effect as an anti-theft device, and thus not only has a high penetration rate, but also has a high degree of certainty as a highly reliable anti-theft device and has gained the trust of motorcycle users. That is the current situation.

[0008]

However, since such a U-shaped lock 101 is used by attaching it to a wheel, it has the following disadvantages. (1) Since the wheel is mounted at a low position, it cannot be mounted or removed unless it is squatted down, and the mounting / removing work is considerably troublesome. In addition, at night or the like, since the lighting is blocked by the vehicle body and the hand tends to be dark, the workability of attachment and detachment may be extremely deteriorated. (2) If a person who intends to steal prepares a tool that can sufficiently cut and break even a sturdy U-shaped lock, the cutting and breaking work is the same as the installation and removal work. Since the user is required to squat down, it is difficult to find the crime because the user can work while hiding his / her hands behind his back. In particular, in a place where many motorcycles are parked, they are completely hidden behind the motorcycles, making it more difficult to find them. This is an adverse effect due to the low mounting position. Further, as similar to the U-shaped lock, a wire-type lock and a chain-type lock are also known. However, since they are inferior in strength to the U-shaped lock, they are more easily damaged. (3) Regardless of two-wheeled vehicles or four-wheeled vehicles, the periphery of the wheels is a particularly easy-to-dirt portion, and even if it is cleaned frequently, it gets dirty quickly. Since the U-shaped lock is to be mounted on the wheel, the U-shaped lock is also easily soiled, and the hands are often stained during the mounting / removing operation. In particular, since the exhaust pipe and the exhaust port are provided near the rear wheel of the motorcycle, as shown in FIG.
The portions S2 and S3 are liable to be stained with oil, and the clothes may be rubbed with the oil stains near the exhaust port and the vicinity by the carelessness at the time of attachment / detachment work, and the clothes may be stained. Since this oil stain cannot be completely removed even after washing, the clothes may be spoiled. (4) Further, since the exhaust pipe is hot immediately after traveling, if a hand touches the exhaust pipe in the work of attaching the U-shaped lock, a burn may occur.

[0009] Because of such a problem, when parking a bicycle, there is often a case where the user hasten in a hurry without time, or neglected to attach a U-shaped lock because he thought it would be okay because only a little time was spent. In particular, when a woman is wearing fashionable clothes, she does not like to stain her hands and clothes and sometimes parks her bicycle without dare to wear a U-shaped lock while thinking that she is careless.

[0010] Therefore, the U-shaped lock has a high penetration rate and can be expected to have a high effect. However, the mounting and detaching work is not easy. It is lower than, and despite having a U-shaped lock, because it was not installed,
It is the present situation that the person who meets the damage of the theft does not end.

By the way, among the two-wheeled vehicles, the arrangement of the steering devices and switches around the handle of the scooter, which is particularly popular, is as shown in FIG. Such devices and switches are arranged so that they can be operated without removing their hands from the handle grips 6R and 6L during driving. In a scooter, devices operated by foot are provided in only a few types of vehicles. It is configured so that it can be operated only by hand in most vehicle types.

Among them, the handle grip 6R and the front brake lever 7, which are operated by the right hand, are common to all motorcycles irrespective of vehicle types, such as scooters, clutches, and motorcycles requiring transmission operation. However, in a scooter or the like that does not require a clutch operation, as long as the handle grip 6R and the front brake lever 7 can be operated, the driving operation is simplified as the driving becomes possible.

However, conversely, if the handle grip 6R (accelerator grip) and the front brake lever 7 operated by the right hand cannot be freely operated, the operation of the motorcycle becomes impossible.

The inventor paid attention to the arrangement of the steering device of the motorcycle, and covered and concealed the handle grip portion and the brake lever or the clutch lever with a robust protective cover member so that they could not be freely touched. This has led to the development of a motorcycle anti-theft device that disables the operation of the motorcycle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a motorcycle anti-theft device and a motorcycle anti-theft device which disable a free operation of a handle grip and a brake lever or a clutch lever. And

[0016]

SUMMARY OF THE INVENTION A motorcycle anti-theft device according to the present invention makes it impossible to steer a motorcycle. The anti-theft system is designed to cover a handle grip of the motorcycle and a brake lever or a clutch lever. A protection cover member provided on the hand grip portion and made of a material having high rigidity; a mounting member provided on the handle grip portion for mounting and fixing the protection cover member to the handle grip portion; and the protection cover member. , For the mounting fixture,
Locking means for locking the mounting fixture so that it cannot be removed. Here, as the material having high rigidity, a metal material is usually adopted, but high rigidity is required because a third party breaks the protective cover member and touches the handle grip portion and the front brake lever. In other words, any other material that satisfies such conditions can be used as a material equivalent to a metal material. Further, the locking means may be any one that makes it impossible for a third party to remove the protective cover member from the fixture, and may be provided on any of the protective cover member or the fixture, It may be configured by combining an element movably provided on the protective cover member and another element provided on the fixture.

With this configuration, the protective cover member is fixed to the mounting member of the handle grip portion of the two-wheeled vehicle so as not to be detachable via the locking means, and the handle grip portion, the brake lever or the clutch are fixed by the protective cover member. The lever is covered. The protective cover member is made of a highly rigid material, and covers the handle grip portion (accelerator grip) and the front brake lever or the clutch lever.
When the protective cover member is fixed by the locking means, the motorcycle cannot be operated because the handle grip, the front brake lever or the clutch lever cannot be freely touched and cannot be operated. Is done.

The protective cover member has a tubular cover body having one end opened and the other end closed, and a grip holder having a tubular portion fitted inside the handle body inside the cover body. It is desirable to provide

With this configuration, the cylindrical holder body of the grip holder of the protective cover member is externally fitted to the handle grip, so that the handle grip and the brake lever or the clutch lever have a fixed positional relationship. Thus, the protective cover member is attached, and the protective cover member is easily stored in the protective cover member so that it cannot be touched.

In the above-described anti-theft device for a motorcycle, the attachment is provided with a rod-shaped member having a base end portion inserted and fixed in the handle grip portion and a front end portion protruding outside, and the front end portion is directed toward the base end side. A tapered portion whose diameter gradually increases, and an engaged portion formed on the base end side of the tapered portion, wherein the locking means is movably provided on the protective cover member, and A locking member having a distal end portion removably engaged with the engaged portion of the rod-shaped member, and a biasing member for biasing the locking member in a direction to be engaged with the engaged portion;
It is possible to have a cylinder key unit that is linked to the base end of the locking member and that releases the engagement between the engaged portion and the locking member. Here, "linkage"
The base end of the locking member and the cylinder unit are connected in some way, which means that the engagement between the engaged portion and the locking member can be released by operating the cylinder unit. .

According to this structure, since the locking member on the protective cover member side is urged by the urging member in the direction of engaging with the engaged portion on the handle grip portion side, the protective cover member is By providing so as to cover the handle grip portion and the brake lever or the clutch lever, the locking member moves on the surface of the tapered portion while the tip portion is guided by the tapered portion,
Finally, it is engaged with the engaged portion. In this engaged state, the engagement member is urged by the urging member in the direction in which the engagement member engages with the engaged portion, so that their engagement relationship is not released. Then, by performing a key operation of the cylinder key unit, the locking member is retracted in a direction opposite to the biasing direction by the biasing member, so that the engagement between the engaged portion and the locking member is released. It will be easy.

Further, the mounting tool includes a rod-shaped member having a base end portion inserted and fixed in the handle grip portion and a front end portion protruding outside, and an engaged portion is formed at the front end portion. A locking means movably provided on the protective cover member, a locking member having a distal end portion removably engaged with an engaged portion of the rod-shaped member, and a locking member linked to a base end portion of the locking member; It is also possible to have a cylinder key unit for engaging and disengaging the engaged portion and the locking member.

With this configuration, the protective cover member is provided so as to cover the handle grip portion and the brake lever or the clutch lever, and the locking member moves by performing a key operation of the cylinder key unit. Engagement and disengagement between the engaged portion and the locking member are easily performed.

In such a case, while the engaged portion of the rod-shaped member is a circumferential groove, the tip of the locking member is
If the base end portion has an engagement hole that is linked to the cylinder key unit as the cutout concave portion that is removably engaged with the orbiting groove portion, the engaged portion and the locking member can be formed with a simple structure. Can be reliably performed.

Further, the protective cover member may have an extension cover portion which covers a fixing screw and switches of a rearview mirror located at a central portion side of the handle grip portion.

With this arrangement, the extension cover covers the fixing screws and switches of the rearview mirror mounted near the handle grip, so that the rearview mirror cannot be removed and the rearview mirror cannot be removed. Theft can be avoided, and by covering the switches, mischief of the switches is also prevented.

Further, the anti-theft device for a motorcycle according to the present invention utilizes the mounting device when a mounting device (including a device that can be used as a mounting device) is already provided in the vicinity of a handle grip portion of the motorcycle. The operation of the two-wheeled vehicle is disabled by attaching the two-wheeled vehicle. Specifically, a protective cover member made of a rigid material provided on the hand grip portion so as to cover a handle grip portion of the motorcycle, a brake lever or a clutch lever, and a protective cover member provided on the protective cover member, Protective cover member,
Locking means is provided for the mounting fixture so as to be irremovably locked from the mounting fixture. In this case, various shapes are conceivable for the attachment provided near the handgrip portion of the motorcycle, and according to the shape of the attachment, the shape of the portion for locking the attachment is also described above. Various shapes will be adopted in order to disable the operation of the motorcycle.

With this configuration, the handle grip and the brake lever or the clutch lever can not be detached by the protective cover member by effectively using the attachment already provided near the handle grip of the motorcycle. Since the cover can be covered, in a state where the protective cover member is irremovably locked, a third party cannot freely touch the handle grip portion, the front brake lever or the clutch lever, and can operate it. No, it is impossible to control the motorcycle.

[0029]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an entire scooter (motorcycle) with a motorcycle anti-theft device according to the present invention attached thereto.
FIG. 2 is an exploded perspective view of the motorcycle anti-theft device according to the present invention, shown in relation to a scooter handle portion.

As shown in FIGS. 1 to 3, the handle grip 6 on the right side of the handle operation unit 3 in the motorcycle 1.

Denotes a right protection cover member 21R, and the handle grip 6L and the rear brake lever 10 on the left side of the handle operation unit are covered by the left protection cover member 21L. The two protective cover members 21R, 21L are attached to the handle grips 6R, 6L.
(Only the right side portion is shown), which is attached and fixed using a locking means described later, so that the handle grip portions 6R and 6L are fixed.
In this state, the user cannot freely touch the handle grips 6R, 6L, the front brake lever 7, and the rear brake lever 10, and cannot operate the motorcycle 1. In this way, the protective cover members 21R, 21L, the attachment 31R, and the locking means constitute left and right motorcycle anti-theft devices 20L, 20R that disable the operation of the motorcycle.

In the following description, since the left protective cover member 21L has the same shape and structure as the right protective cover member 21R except that it is symmetrical, only the right protective cover member 21R will be described. .

The right protective cover member 21R is shown in FIG.
As shown in detail in FIG. 2, a metal cover main body 22R which is inserted into the cylindrical shape with one end opened and the other end closed to cover the handle grip 6R (accelerator grip) and the front brake lever 7 is inserted. It has. Here, the reason why the cover body 22R is made of metal is that the cover body 22R is broken by a third party and the handle grip portion 6R is made.
Or the front brake lever 7 cannot be touched. In this case, the surface may be coated with a resin to improve the appearance (a resin coating layer is formed around the cover body 22R in FIG. 2). An example is shown by a broken line), but instead of metal, it may be made of plastic. However, if it is made of plastic, from the viewpoint of prevention of theft, it has high strength so that it is not easily broken. It is desirable to use fiber reinforced plastic.

A clip holder 23 which is fitted to the handle grip 6R is fixed inside the cover body 22R. The grip holder 23 has a cylindrical holder main body 23a (cylindrical part) fitted to the handle grip portion 6R, one end fixed to the holder main body 23a by welding, and the other end provided on the inner surface of the cover main body 22R. Mounting portions 23b, 23b each having a U-shaped cross section fixed by welding are provided. The holder main body 23a is fixed to one side in the cover main body 22R so that the holder main body 23a and the inner surface of the cover main body 22R are in a state where the holder main body 23a is externally fitted to the hand grip portion 6R. A space in which the front brake lever 7 is located is formed therebetween.

An opening 22a is formed at the other end of the cover body 22R. The cylinder key unit 24 is supported so that the key insertion portion 24a of the cylinder key unit 24 is exposed through the opening 22a. It is attached to the inner surface of the cover body 22R via the bracket 25.

The support bracket 25 is attached to the cover body 2.
It has a bent shape having a base 25a fixed to the inner side surface of the 2R by welding, and a tip 25c extending substantially parallel to the base 25a from the base 25a via an intermediate portion 25b. Then, at the tip portion 25c of the support bracket 25,
The base 26b of the guide member 26 having the guide groove 26a is mounted and fixed together with the mounting portion 24b of the cylinder key unit 24 with a screw 27. A locking claw 28 having a notch concave portion 28a at a distal end portion is slidably (movably) engaged with the guide groove 26a of the guide member 26, and a spring member 29 is provided between the locking claw 28 and the guide member 26. Is provided, and the notch concave portion 28a of the locking pawl 28 is urged in a direction to engage with a later-described circumferential groove portion 32a. An engagement hole 28b is formed at the base end of the locking claw 28, and the cylinder key unit 24 is inserted into the engagement hole 28b.
When the movable portion 24c is engaged with the locking claw 28, the cylinder key unit 24 is linked to the locking claw 28. When the cylinder key unit 24 is unlocked by operating the key, the locking claw is opposed to the spring force of the spring member 29. 28 is forcibly retracted, and the engagement between the cutout recess 28a and the circumferential groove 32a is released.

As described above, the locking pawl 28 serving as the locking member, the spring member 29 serving as the urging member, and the cylinder key unit 24 allow the protection cover member 21R to be provided.
Is fixed to the attachment 31R in such a manner that it cannot be detached from the attachment 31R.

On the other hand, as shown in FIG. 3, the handle grip 6R is formed in a triple structure of a handlebar pipe 6a, an accelerator wire holder 6b and a grip rubber 6c, and a protective cover member 21R is provided at the grip end. A mounting tool 31R for mounting and fixing is provided. The attachment 31R includes a rod-shaped member 32 whose base end portion is inserted and fixed in the handle grip portion 6R (specifically, the handlebar pipe 6a) and whose distal end portion projects outside.
2 includes a cap bolt 33 for inserting and fixing the base end portion into the handlebar pipe 6a, a split collar 34, and a truncated conical nut 35. The rod-shaped member 32 has a tapered portion 32a whose diameter gradually increases toward the base end side.
And a locking claw 2 formed on the base end side of the tapered portion 32a.
8 (locking member) has a circumferential groove portion 32b (engaged portion) with which the notched concave portion 28a is detachably engaged. In order to insert and fix the base end portion of the rod-shaped member 32 of the attachment 31R, a hole is formed in the grip rubber 6c.

In this way, the handle grip 6
When the protection cover member 21R is pushed into the R and front brake lever 7 so as to be fitted to the outside, the locking claw 28 is urged by the spring member 29.
The notch recessed portion 28a of FIG. 8 engages with the tapered portion 32a of the attachment 31R and is gradually guided to the larger diameter side, and finally is smoothly engaged with the circumferential groove 32b of the attachment 31R.
The locking claw 28 is configured such that the notch recess 28a is elastically engaged with the orbital groove 32b by the spring member 29, so that the protective cover member 21R is irremovably locked.

When the protective cover member 21R is removed, the movable portion 24c of the cylinder key unit 24 is engaged with the engaging hole 28b of the locking pawl 28. By inserting and rotating the key, the locking pawl 28 retreats against the spring force of the spring member 29, and their engagement is released. Therefore, the protection cover member 21R can be removed. When the movable portion 24c of the cylinder key unit 24 is engaged with the engaging hole 28b of the locking pawl 28, the engaging state is maintained, and the locking pawl 28 is It can be moved only within a certain range in relation to the spring force.

Accordingly, as a device for protecting the motorcycle from theft, the U-shaped lock is equivalent in terms of effect and reliability, but has a very simple mounting / removing workability, thereby shortening the time. A higher anti-theft effect can be exhibited by obtaining a high attachment ratio even when bicycles are parked for a long time.

Incidentally, the anti-theft device according to the present invention comprises:
It can be attached to either the left or right huddle grip,
It is intended to prevent a burglary person from driving freely to prevent theft. Therefore, at least the right-hand handle grip portion 6R (accelerator grip) and the right-hand portion where the front brake lever 7 is provided should be mounted. Is enough.

However, if the anti-theft device is mounted not only on the right handle grip 6L but also on the left handle grip 6L, the rear brake lever 7 provided on the left handle grip 6L cannot be operated. However, it is very difficult to push and move the scooter, especially if there is a slight uphill and downhill slope, moving the scooter without braking is a very dangerous act without braking, so try to force it and steal it It is also possible to give up those who do.

When the motorcycle is to be stealed by destroying the anti-theft device, the handle grips 6R and 6L are located at the highest position of the motorcycle. Is more noticeable in the surroundings and is more noticeable.

In addition, if the anti-theft device is made of a material and structure stronger than the handle grips 6R, 6L of the motorcycle, the handle grips 6R, 6L of the motorcycle are also damaged when the anti-theft device is destroyed. There is a high possibility that even if the anti-theft device is destroyed by any method, the steering device of the handle grip portion will be damaged, and eventually it will be impossible to drive and it will not be possible to escape. For this purpose, it is effective to create an anti-theft device with a small gap to the handle grip so that it fits snugly. The only way to destroy the equipment is to cut it with time, for example, using a saw, and it is almost impossible to work on the spot where the motorcycle is stolen, because it is noticeable. Becomes

Also, being attached at a high position such as the handle grip and being conspicuous means that it is easy to appeal to those who are going to steal the use of the anti-theft device. It is also difficult to be done. Also, as described above, when the user tries to push and take away the device, the protective cover member stands out easily, so that it is easy to catch the eyes of the surrounding people, and it is easy to find that the user is stealing.

As described above, according to the present invention, the start-up of the engine and the escape of the vehicle are prevented by covering the handle grip, the brake lever, and the like. It seems that there is a possibility that it can be pushed away and removed, compared to an object that can not be moved unless it is removed like this, but it seems that the effect is slightly inferior, but first, it is very noticeable that you are wearing it, it is very noticeable when you try to break it That is, the feature that the handle grip portion is also likely to be broken can be sufficiently compensated for the lacking portion, and furthermore, the locking means,
If it is configured as shown in FIG. 2, the locking operation can be performed with one touch. For example, in a scooter, a pocket storage space provided under a foot or a front car during driving,
If you store it in the pocket of your clothes, it can be taken out immediately, so it is almost always attached even when parking for a short time or when you are in a hurry, just like the handle lock part of the main key part. It is conceivable that the above mounting rate is obtained, and as a result, a theft prevention effect higher than that of the U-shaped lock can be expected.

Further, since the handle portion is a portion that is much less likely to be stained than the wheel portion to which the U-shaped lock is attached, there is also a great advantage that there is no fear of getting dirty hands or clothes and there is no risk of burns. .

In the above-described embodiment, the locking claw 28 as the locking member is urged by the spring member 29 in the direction in which the locking claw 28 is engaged with the orbiting groove 32b as the engaged portion. The present invention is not necessarily required to do so, and as shown in FIG. 4, it is also possible to directly switch between engagement and disengagement by key operation of the cylinder key unit 24. It is possible. That is, the guide walls 25d on both sides of the distal end portion 25c of the support bracket 25A.
The locking pawl 28A is movably provided along the
By engaging the movable portion 24c of the cylinder key unit 24 with the engaging hole 28b of the 8A, the cylinder key unit 24 is linked to the base end of the locking pawl 28A, and the key of the cylinder key unit 24 is operated to lock the locking pawl 28A. Notch recess 28
a can be engaged with and disengaged from the circumferential groove 32b of the rod-shaped member 32. In this case, the locking pawl 28A
As shown in FIG. 5 (a), the notch recess 28a of the lock member 28A is engaged with the orbital groove 32b of the rod 32 (locked state), as shown in FIG. FIG. 5 (b) shows a state in which the engagement with is released (unlocked state). The change in the engagement between the notch recess 28a of the locking claw 28A and the orbital groove 32b of the rod-shaped member 32 is the same in the embodiment shown in FIG.

In addition, the rearview mirrors 14 and 15 are very susceptible to theft, and mischief of switches (for example, the switching between low and high of the headlight is often set to high, and In order to avoid them, as shown in FIG. 6, the protective cover members 21R 'and 21L'
Fixing screws (not shown) and switches (not shown) for the rearview mirrors 14 and 15 located at the center of the handle grips 6R and 6L (cell switch 8 for starting the engine, headlight low / high switch 11, turn signal switch) 12R and extension cover portions 41R, 4 covering the horn switch 13).
It is also possible to have 1L. The extension cover portions 41R and 41L are connected to the handle grip portion 6.
Rearview mirrors 14 and 1 mounted near R and 6L
Screw covers 41Ra and 41La covering the fixing screws 5
And switch covers 41Rb and 41 connected to the switch
Lb. Therefore, the extension cover portions 41R, 41L
The fixing screws of the rearview mirrors 14 and 15 are covered by the screw covers 41Ra and 41La of the rearview mirror 1.
4 and 15 cannot be removed and the switch cover 41
Since various switches are also covered by Rb and 41Lb, it also helps to prevent mischief of the switches.

In the above-described embodiment, the attachment is attached to the handle grip. However, the present invention is not limited to this, and the attachment (can be used as an attachment) near the handle grip of a motorcycle. If the attachment is already provided, the attachment can be used, so that the motorcycle is irremovably attached to the attachment, as in the case described above, It is also possible to disable the operation of the motorcycle. In this case, the motorcycle anti-theft device has a configuration excluding a mounting component which is a component of the above-described motorcycle anti-theft device,
That is, the handle grip portion of the motorcycle, a protective cover member provided on the hand grip portion to cover a brake lever or a clutch lever and made of a material having high rigidity, and a protective cover member provided on the protective cover member, the protective cover member It is to be noted that the mounting device is provided with a locking unit for locking the mounting unit so that the locking unit cannot be detached from the mounting unit. Needless to say, the shape and structure of the locking unit are appropriately changed according to the shape of the mounting unit. Nor.

The present invention is embodied in the form described above, and has the following effects.

In the motorcycle anti-theft device according to the present invention, a protective cover member made of a highly rigid material is engaged with the attachment of the handle grip so as to cover the handle grip and the front brake lever or the clutch lever. In this state, the handle grip, the front brake lever or the clutch lever cannot be touched, and they can be freely operated when the protective cover member is mounted and fixed. Can not drive the motorcycle. Therefore, the motorcycle can be prevented from being stolen with a simple configuration in which the protective cover member is provided.

If the protective cover member is provided with a grip holder having a cylindrical portion fitted to the handle grip portion inside the cylindrical cover main body, the handle grip portion has a cylindrical holder as a grip holder. With a simple operation of externally fitting the main body, the protective cover member can be attached in a fixed positional relationship with the handle grip portion and the brake lever or the clutch lever, and it is possible to cover them comfortably. .

The attachment is a rod-shaped member having a base end portion inserted and fixed in the handlebar pipe of the handle grip portion and a tip end portion projecting to the outside, and the tip end portion gradually decreases in diameter toward the base end portion side.
