BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a knob of a shift operation lever of a vehicle transmission.

[0002]

2. Description of the Related Art As a knob mounting structure of a shift operation lever of a vehicle transmission, for example, as shown in Japanese Utility Model Laid-Open No. 43540/1988, the knob is inserted into the operation lever at the upper end of the knob body and upwardly. Push the compression rod protruding to the position plate to form a push button fitting hole for disengaging the position pin with the position plate, insert the knob body into the upper end of the operation lever, and The nut is screwed and fastened to the threaded portion at the upper end of the operating lever, which fits into the escutcheon positioned and arranged at the upper end of the operating lever and protrudes from the bottom of the fitting hole. Are fixed to the upper end of an operation lever.

[0003]

The push button is fitted into the fitting hole after the nut is tightened to the upper end of the operating lever of the knob body. Therefore, when the knob body needs to be removed, this push button is required. Workability is degraded due to the removal work of

[0004] Further, since the push button cannot be sub-assembled to the knob body, there is a disadvantage that the number of man-hours for parts management and work in the body assembly line increases. Further, since the nut is tightened in the fitting hole at the upper end of the knob main body, the fitting hole needs to secure a tool space for the nut tightening operation, and the degree of freedom in shaping the knob main body is restricted. There are disadvantages. The same can be said for an operation lever for a manual transmission in which the fitting hole at the end of the knob body is closed with an ornament without providing a push button.

Accordingly, the present invention provides a knob mounting structure of a speed change operation lever which can be easily mounted and removed, and can increase the degree of freedom in shaping the knob body.

[0006]

Means for Solving the Problems At the upper end of the operation lever,
While inserting and attaching the knob body and an escutcheon connected to the lower end of the knob body, a push button is fitted into an arrangement hole opened on the upper surface of the knob body, and the operation lever is attached to the operation lever by the push button. In a shift operation lever adapted to push the inserted compression rod, a shift stop means for restricting upward movement of the push button is provided, and a sliding contact portion between the operation lever and the knob body is provided.
A positioning step is formed to engage with each other to restrict the downward movement of the knob body, and a sliding part is engaged with the sliding contact portion between the operation lever and the escutcheon to regulate the upward movement of the escutcheon. While the stopper mechanism is provided, female and male threads are formed in the knob body and the escutcheon, these female and male threads are screwed together, and the knob body and the escutcheon are fastened and fixed.

[0007]

[Function] By screwing the female and male threads of the knob body and the escutcheon, the knob body is pressed against the operation lever at the stepped portion, while the escutcheon is pressed against the operation lever at the retaining mechanism. The knob body and the escutcheon are securely fixed to the operation lever.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an operating lever, into which a compression rod 2 having a lower end protruding a position pin (both not shown) engaged with a groove of a position plate is inserted. A pair of flat surfaces 3 are formed on the upper end portion of the operation lever 1 so as to face each other to form a non-circular shape, and a step portion 4 is formed on a molding base thereof.

Reference numeral 5 denotes a knob body inserted and arranged at the upper end of the operation lever 1.
A non-circular engaging hole 6 is formed to engage with the non-circular portion having the flat surface 3 formed therein. A stepped portion 7 is formed, and a downward movement is regulated by engagement with the stepped portion 4 so as to be positioned and arranged. The upper part of the engagement hole 6 of the knob body 5 is provided as a mounting hole 8 for a push button 9, and the mounting hole 8 has a push button 9
The compression rod 2 protruding from the upper end of the operation lever 1 is pushed downward by the push operation of the push button 9, and the engagement of the position pin with the position plate (not shown) is released. is there. Note that the retaining means 20 of the push button 9 is
Click 9a of the button 9 to the step 1 of the button guide 10.
0a. Further, a female screw portion 11 for connecting an escutcheon 12, which will be described later, is formed below the engagement hole 6 of the knob body 5.

Reference numeral 12 denotes an escutcheon which is inserted into the upper end of the operating lever 1 and is connected to the lower end of the knob body 5. The escutcheon 12 is prevented from moving upward with respect to the operating lever 1 by a retaining mechanism 14. I have.

In this embodiment, the retaining mechanism 14 includes a ring 16 fitted in a groove 15 formed on the outer periphery of the operation lever 1.
And a step 17 formed below the lever insertion hole of the escutcheon 12 and engaged with the ring 16. On the outer periphery of the upper part of the escutcheon 12, a male screw part 13 is formed which is screwed to the female screw part 11 of the knob main body 5. And operation lever 1
Is fastened and fixed.

According to the structure of the above embodiment, the escutcheon 12 is inserted into the upper end of the operating lever 1 and
The ring 16 is fitted in the groove 15 of the
After the upper part of the operation lever 1 is stopped, the knob body 5 with the sub-assembly of the push button 9 is similarly inserted into the upper end of the operation lever 1 to engage the engagement hole 6 with the non-circular end. The knob body 5 is positioned by engaging the parts 4 and 7 with each other.
Then, the end of the male thread portion 13 of the escutcheon 12 is inserted into the female thread portion 11 of the knob main body 5, and the escutcheon 1
The step 7 of the knob body 5 is pressed against the step 4 of the operation lever 1 by rotating the knob 2 and screwing the female and male screw sections 11 and 13 together.
Is pressed against the ring 16 of the operating lever 1, and the knob body 5,
The escutcheon 12 can be securely pressed and fixed to the operation lever 1. Since this fastening operation can be performed by rotating the escutcheon 12 outside, the operation can be easily performed.

On the other hand, when it is necessary to remove the knob body 5 for replacement of the operating lever 1, compression rod 2, knob body 5, etc., maintenance, inspection, etc., the above-mentioned assembling procedure is reversed, that is, If the escutcheon 12 is rotated to release the male screw portion 13 from the female screw portion 11, the knob body 5 can be easily removed from the operation lever 1, and the push button 9 does not need to be removed. Work can be performed easily.

The knob body 5 does not need to secure a tool space inside the knob body 5 unlike the conventional structure in which the knob body 5 is fixed to the upper end of the operation lever by a nut. In addition to being able to be enlarged, the push button 9 can be sub-assembled to the knob main body 5, so that there is an advantage that the number of man-hours for parts management on the vehicle body assembly line can be reduced.

[0016] It is not possible pullout prevention mechanism 14 described above to be limited to the examples, have good even ones of the hook structure.

[0017]

As described above, according to the present invention, the knob body can be easily assembled and removed from the outside by screwing or loosening the female body and the male thread of the knob body and the escutcheon. In particular, the removal work does not involve removal of attached parts such as push buttons and ornaments mounted on the top of the knob body, so that the work can be remarkably improved, and a tool space is secured inside the knob body. Since there is no need, the degree of freedom in shaping the knob main body can be increased. Also, push button
Since falling off from the arrangement hole is prevented by the retaining means,
Workability is also significantly improved.
