Description

[Detailed description of the invention] The present invention relates to a shift lever device for a vehicle in which a shift knob is formed by simultaneous integral molding of a knob main body made of a hard resin and a knob exterior made of a soft resin. The soft resin constituting the body is designed to protrude into a hollow hole inside the knob main body and come into elastic contact with an operating member movably provided in the hollow hole.

The following is an example of the present invention shown in Figures 1 and 2.
This will be explained with reference to the figures. Reference numeral 1 denotes a shift lever of an automatic transmission rotatably installed on the floor of a vehicle, for example, an automobile, and a shift knob 2 is fixed to the tip of the shift lever with screws 3, 3. In the following, the shift knob 2 will be described in detail.The main body of the shift knob 2 is a cylindrical knob made of hard resin such as polyacetal. Two upper and lower step portions 6 and 7 are formed in the intermediate portion, and four communication holes 6a and 7a are provided near the step portions 6 and 7, respectively, for communicating between the outer wall of the knob main body 4 and the inside of the hollow hole 5. It is being Reference numeral 8 denotes a knob exterior body which is simultaneously integrally molded with a soft resin such as soft vinyl chloride so as to cover the outer periphery of the knob main body 4. During molding, the resin material flows into the hollow hole 5 through the communicating holes 6a and 7a. Annular contact portions 9 and 10 as soft protrusions are integrally molded on the upper surface of the stepped portion 6 and the lower surface of the stepped portion 7, respectively. Reference numeral 11 denotes a rod that passes through the inner peripheral portion of the shift lever 1, and a cylindrical connecting member 12 having a female threaded portion 12a on the inner surface is screwed and connected to a threaded portion 11a at the upper end of the rod. And the connecting member 12
An engaging pawl 12b and a flange 12c are protruded from the outer periphery of the step 7, and the flange 12c faces the annular contact portion 10 that is in contact with the lower surface of the stepped portion 7. 1
Reference numeral 3 designates a push button as an operating member provided in the hollow hole 5 so as to be slidable up and down, and an engaging claw 12c of the connecting member 12 is engaged with an engaging hole 13a at the lower end of this push button.
Then, the lower end of the cylindrical portion 13b on the outer periphery of the push button 13 contacts the upper surface side of the stepped portion 6.
is facing.

Since the rod 11 is biased upward (in the direction of arrow A) by a biasing means (not shown), normally the flange 12c is made of a soft resin.
0, thereby preventing the push button 13 or the connecting member 12 from producing chattering noise due to vibrations or the like during running.

Also, when shifting the shift lever 1 to the "P" position, from the "P" position to the "R" position, from the "D" and "N" positions to the "R" and "L" positions, As is well known, when shifting to a position, a rotation restriction is applied to prevent misshifting, so in this case, it is necessary to release the rotation restriction by pressing the push button 13 before shifting. When the push button 13 is pushed in, the lower end of the cylindrical part 13b comes into elastic contact with the annular contact part 10, and the pushing of the push button 13 is restricted, so that no shock is applied to the finger and no impact noise is generated.

By the way, in the past, the annular contact parts 9 and 10 were manufactured as separate parts or were omitted, which resulted in an increase in the number of parts, which made assembly difficult, or caused impact noise when the push button was operated. However, with the above configuration, it is possible to reliably prevent collision noise when operating a push button, chatter noise during driving, etc. without increasing the number of parts at all.

FIG. 3 shows another embodiment of the present invention, and only the parts different from FIGS. 1 and 2 will be described. 14 is a shift knob; 15 is a substantially T-shaped knob main body made of hard resin; the lower end of a hollow hole 16 formed inside is fitted into the upper end of the shift lever 1; The horizontal portion of the hollow hole 16 is open at one end and forms a stepped portion 17 near the other end.
A communication hole 17a that communicates between the outer wall of No. 5 and the inside of the hollow hole 16
There are multiple protruding pieces. Reference numeral 18 denotes a knob exterior body integrally molded with a soft resin so as to cover the outer periphery of the knob main body 15, and the communicating hole 17 is formed when this is molded.
A soft resin material flows into the hollow hole 16 through a, and an annular contact portion 19 as a soft protrusion is integrally molded on the side surface of the stepped portion 17. On the other hand, 20 is a push button as an operation member movably provided in the horizontal part of the hollow hole 16, and an engagement hole part 21 is formed in the middle part of this button by penetrating it vertically. 21
A substantially arc-shaped pressing portion 21a is formed on the right wall. A compression coil spring 22 is inserted on the left side of the push button 20, and the spring force of the compression coil spring 22 applies a return force to the push button 20 in the direction of arrow B, which is the right direction. . A rod 23 is vertically movably inserted into the shift lever 1 and urged upward by a spring (not shown), and its upper end is positioned in the engagement hole 21 to prevent the push button 20 from coming off. A large diameter portion 24 is integrally fixed. This large diameter portion 24 is formed with an inclined cam surface 24a that contacts the pressing member 21a, and the inclined cam surface 24b is formed on the side surface of the large diameter portion 24 by the spring force of the compression coil spring 22. It is provided so that it is brought into pressure contact. Then, when the push button 20 is pushed to the maximum in the direction opposite to the arrow B, the push button 20 comes into elastic contact with the annular contact portion 19, so that the same effect as in the embodiment described above is achieved.

In the present invention, the soft resin constituting the knob exterior protrudes into the hollow hole inside the knob main body and can come into elastic contact with the operating member movably provided in the hollow hole, so the number of parts is increased. Therefore, it is possible to provide a shift lever device for a vehicle that has an excellent effect of being able to prevent collision noise when operating an operating member, chatter noise while the vehicle is running, etc.
