The adhesive has not spread all over the inner surface of the grip 4. In this case, sufficient adhesive strength cannot be obtained, and the grip 4 is removed from the operation lever main body 3. It becomes easy to come off.

[0009]   As described above, the resin grip is press-fitted into the operation lever body, so the lever -The above-mentioned axis is determined by the ratio of the outer diameter of the main body to the inner diameter of the grip before press fitting (press fitting margin) The shape and size of the directional gap and the circumferential gap are different. That is, the axial direction The flow of the adhesive injected from the gap depends on the press-fitting margin. According to Between the outer diameter of the lever body and the inner diameter of the grip (especially the inner diameter of the grip) between lots. The adhesive strength also varies due to the variation.

[0010]   As the adhesive, a cyanoacrylate-based adhesive is generally used, Since the adhesive strength of this adhesive has a great influence on the storage condition, there are variations in adhesive strength. It is easy to occur.

[0011]   Also, the adhesive will deteriorate after bonding and it will not be possible to obtain sufficient fixing strength. There are cases.

[0012]   In addition, in order to use the adhesive, remove the oil previously attached to the operation lever body. Since it has to be removed, a process for this is required, resulting in high cost. Cause.

[0013]   In particular, in recent years, this grip has been added to improve the feel of the grip. Increase in those made of soft resin (for example, soft polyvinyl chloride) There is a tendency, but when the grip is made of soft resin, the plasticizer required for this is As it increases, it will adversely affect the adhesive used to secure the operating lever body to the grip. These problems will become even more prominent, as they will accelerate their deterioration. The development of technology to solve this was eagerly awaited.

【Example】

  Hereinafter, an embodiment of an operation lever according to the present invention will be described with reference to a parking brake for a vehicle. A case where the rake operation device is used will be described as an example.

[0022]   FIG. 1 shows the structure of a parking brake operating device for a vehicle according to this embodiment. FIG.

[0023]   In such a device, the operating lever 10 includes the operating lever body 3 and the operating lever. The grip 4 is mounted and fixed to the tip of the main body 3. And The operation lever body 3 can be freely rotated around the pin 13 provided on the sector 12 as a rotation center. It is mounted so that it can rotate. In addition, at the base of the operation lever body 3, The brake cable 14 is connected. According to this configuration, the operation lever body 3 is rotated in the direction indicated by A in the figure, the brake cable 14 is indicated by A'in the figure. The brake (not shown) is activated by pulling in the direction indicated by the arrow. On the contrary, this operation record When the bar main body 3 is rotated in the direction indicated by B in the figure, the brake cable 14 will be It is pushed out in the direction indicated by middle B ', and the brake is released.

[0024]   A pole 15 is provided in the operation lever body 3. This pole 15 Is rotatably supported by a pin 16, and the release rod 1 is attached to one end. In addition to being attached, a claw portion 17 is provided at the other end.

[0025]   When the operation lever 10 is not operated, the release rod 1 has a rod insertion hole. A spring 5 provided inside 18 is biased in the direction indicated by C in the figure. Therefore, a rotational force in the counterclockwise direction (C 'in the figure) is applied to the claw portion 17, and the engagement of the sector 12 is Engages with the stop teeth 12a. This may prevent the operation lever body 3 from rotating. Since the tilt angle of the operation lever body 3 can be fixed to a predetermined angle, The brake operating state or the released state can be maintained.

[0026]   On the other hand, when operating the operation lever 10, the operator holds the grip 4. Then, push the operation knob 2 into the inside of the lever body 3 with the thumb. This allows Lely The rod 1 is pushed out in the direction indicated by D in the figure, and the pole 15 is rotated clockwise (in the figure). Rotate to D '). At this time, the engagement with the locking teeth 12a of the sector 12 is released. Therefore, the operation lever body 3 can be rotated.

[0027]   Here, in the parking brake operating device for a vehicle according to the present embodiment, the A grip core member (first member) that covers the outer peripheral surface of the operation lever main body 3, And a grip surface material (second member) that covers the outer peripheral surface of the grip surface material. ing.

[0028]   FIG. 2A shows the grip 4 in an enlarged manner. In addition, FIG. It is an AA sectional view in a).

[0029]   As can be seen from the figure, in this embodiment, the grip 4 is provided with a grip for forming the first member. And a grip surface member 4b forming a second member. The grip 4 and the operation lever body 3 are fixed by screws 6.

[0030]   The grip core material 4a is formed of a hard material (for example, hard resin or metal) To be done. The hardness of the grip core material 4a at this time is as follows. Has a value such that the grip 4) can be fixed by the screw 6. An example For example, hard polyvinyl chloride, polypropylene, etc. are used as the shape of the grip core material 4a. It can be preferably used as a constituent material.

[0031]   The grip surface member 4b is made of a soft material (for example, soft resin). Be done. This improves the feel when the operator holds the grip 4. This is because you can That is, the hardness of the grip surface material 4b at this time is The value should be such that a person can obtain a favorable feeling when gripping the grip 4. Good. For example, soft polyvinyl chloride is a material for forming the grip surface material 4b. Can be preferably used as

[0032]   The position of the screw 6 (the position where the screw is fixed) is not particularly limited. However However, the operator does not touch the hand when gripping the grip 4 and is hard to see It is desirable to set the position. For example, change the position of this screw 6 to boots (parking Hidden in the cover that covers the brake operating device except the tip of the operating lever 10) Position.

[0033]   The method of fixing the grip core material 4a and the grip surface material 4b is particularly limited. Although it is not a thing, there are the following methods, for example.

[0034]   When the grip core material 4a and the grip surface material 4b are made of the same material Both can be fixed to each other by welding. For example, the grip core material 4a Hard polyvinyl chloride is used as a material for forming the grip surface material 4b When soft polyvinyl chloride is used as this, this method can be applied.

[0035]   On the other hand, the grip core material 4a and the grip surface material 4b are made of different materials. When the grip core material 4a and the grip surface material 4b are respectively engaged, By forming a mating portion and an engaged portion and engaging the engaging portion with the engaged portion, Both can be fixed together. FIG. 3 shows an example of such a method. like this In addition, a hole is formed in the grip core material 4a to form an engaging portion 4a ', and a grip surface material 4b is formed. If the convex portion is formed to be the engaged portion 4b ', the engaging portion 4a' and the engaged portion 4b 'are engaged with each other. Both can be fixed by combining. Also, the grip surface material 4b When insert is formed by insert molding, grip core material 4a hole or under It is also possible to fix both by providing a cut. For example , A pipe made of aluminum is used as the grip core material 4a, and the grip surface material 4b This method is applicable when soft polyvinyl chloride is used as the forming material of Wear.

[0036]   As described above, in this embodiment, the grip 4 is attached to the grip core member 4a and the grip table. The grip core 4a is made of a hard material, and the grip core 4a is made of a hard material. Since the table 4b is made of a soft resin, the grip core material 4a (further, Can be fixed with screws 6 and gripped by hand It is possible to obtain the operation lever 10 that is excellent in the feeling at the time.

[0037]   In other words, in the present embodiment, the grip 4 is replaced with the grip core member 4a and the grip table. Because it is composed of 2 layers of 4b, it is hard enough to screw the grip core material 4a. Even if it is made of a material, by forming the grip surface material 4b with a soft material, It does not worsen the feel when grasped.

[0038]   In addition, in this way, the grip core 4a (and thus the entire grip 4) is attached to the screw 6. Therefore, by fixing it, there is no need to use an adhesive. When fixing the grip to the main body, there is uneven adhesive, which has been a problem in the past. Due to variations in the fixing strength, and deterioration of the adhesive may cause the fixing strength to change over time. There is no possibility that the oil will deteriorate, and the oil that adheres to the operation lever body Since it is not necessary to remove the amount in advance, the manufacturing process can be simplified.

[0039]   Further, by fixing the grip 4 with the screw 6, the grip 4 can be gripped even in a vehicle. As it is possible to replace the grip 4, it is convenient when replacing the grip 4 as an option. Is.

[0040]   In addition, when fixing the grip 4 with the screw 6, the parking brake of this embodiment is After mounting the rake operation device on the vehicle, the grip 4 is assembled to the operation lever body 3. You can find it. Therefore, manufacturers of parking brake operating devices When transporting from the field to the automobile manufacturing plant, only the grip 4 should be packed separately and transported. It is also possible to prevent the grip 4 from being damaged during transportation. it can.

[0041]   It should be noted that the present invention is not limited to the embodiments described above, and its gist is Of course, it can be applied by appropriately changing it within the range not to be changed.

[0042]   For example, in this embodiment, a hand for fixing the grip core member 4a and the operation lever body 3 to each other. Although the screw 6 is used as the step, the fixing means is not limited to this. is not. For example, as such a fixing means, an instant adhesion that is conventionally used. Agents may be used. In this case also, the grip core material 4a is made of a hard material. This makes it easier to compare with a conventional grip made of soft resin only. For example, the fixing strength of the instant adhesive can be increased. Therefore, the above It is possible to reduce the variation in fixed strength and the decrease in fixed strength over time. It becomes Noh.

[0043]   Further, in this embodiment, the operation lever of the present invention is used to operate the parking brake for the vehicle. Although the description has been given by taking the case where it is applied to the device as an example, it may be applied to other devices. It's sloppy.

[0044]

[Effect of device]
