1 is a cross-sectional view taken along the line AA of the arrow shown in FIG. 1, FIG. 3 is a cutaway top view of the one shown in FIG. 1, and FIG. 4 is a cross-sectional view taken along the line BB of the arrow shown in FIG. . In the figure, 1 is a shift knob, 2 is a support part, 3 is a belt, 4 is a first gear, 5 is a second gear, 6 is a pinion gear, 7 is a sector gear, 8 is a force transmission part, 9 is a position plate, And 10 are frame bodies. Each configuration will be described below.

First, the shift knob 1 is operated by a driver, and includes a push button 1a, a rod 1b for transmitting an operating force of the push button 1a, and a cam 1c abutting the rod 1b so as to receive the operating force from the rod 1b. A spring 1d for pressing the cam 1c, and a pin 1 formed integrally with the cam 1c
e, a slide block 1f in which the rod 1b is loosely fitted therein and supported by the support portion 2, and a convex portion 1g which is fitted to the belt 3 to attach the slide block 1f to the belt 3.

The supporting portion 2 is composed of a rod for linearly movably supporting the shift knob 1 and is loosely fitted in a hole 1h provided in the slide block 1f.

The belt 3 has the shift knob 1 attached thereto, and is composed of, for example, a metal belt such as a steel belt and a chain, a rubber belt and a synthetic resin belt, and has a concave portion 3a into which the convex portion 1g is fitted. Have

The first gear 4, the second gear 5, the pinion gear 6, and the sector gear 7 form a gear mechanism. The first gear 4 and the second gear 5 are arranged so as to face each other, the pinion gear 6 is integrally formed with the first gear 4, and the sector gear 7 is engaged with the pinion gear 6 to form the first gear. The belt 3 is installed between the gear 4 and the second gear 5.
Here, the diameter of the first gear 4 is set to be larger than the diameter of the second gear 5. The first gear 4 and the second gear 5 are fixed to the frame body 10 by the first support shaft 4a and the second support shaft 5a, respectively. Then, the number of teeth of each gear 4 to 7 is appropriately selected to set the operating force of the shift knob 1 to an appropriate value.

The force transmitting portion 8 has one end connected to the sector gear 7 of the gear mechanism and the other end connected to a transmission (not shown), and is commonly called an operating lever. The force transmitting portion 8 is axially fixed to the frame body 10 by the third support shaft 8a.

The position plate 9 has a step portion 9 with which the pin 1e of the shift knob 1 is engaged, as shown in FIG.
It has a long hole 9b through which a and the convex portion 1g are inserted, and the shift knob 1 is set to "P", "R", "N", "D", "2",
And "1" positions (positions indicated by symbols a to f in FIG. 3) are held at the respective shift operation positions.

It should be noted that the electromagnetic actuator 11 may be added to the structure of the above embodiment if necessary. In that case, the electromagnetic actuator 11 may be composed of a step motor, a solenoid, or the like and connected to the second gear 5. Furthermore, when the electromagnetic actuator 11 operates,
In order to remove the pin 1e from the position plate 9 in conjunction with it, a solenoid (not shown) is added to the cam 1
It is advisable to activate c.

The electromagnetic actuator 11 can be configured to operate upon receiving a control signal from a control circuit (not shown). Thereby, for example, in response to an engine stop operation, the electromagnetic actuator 11 is operated, the second gear 5 is rotated to drive the belt 3, and the operation position of the shift knob 1 is automatically switched to the parking (P) position. It is also possible to perform a so-called vehicle runaway prevention operation.

The embodiment having the above construction operates as follows. For example, when the shift knob 1 is in the position shown by the solid line in FIG. 1, the shift range is the "N" range. When the push button 1a is pressed from this state, the pin 1e is disengaged from the position plate 9, and the shift range can be switched between the "P" range and the "1" range.

When the shift knob 1 is operated, the operating force is transmitted to the belt 3 and the first gear 4 is rotated by the belt 3. When the first gear 4 rotates, the pinion gear 6
Also rotates and the operating force is transmitted to the force transmitting portion 8 via the sector gear 7. For example, when the shift knob 1 is operated to the "P" position, the force transmitting portion 8 is displaced to the "P '" position as shown in FIG. . Similarly, the shift knob 1 is set to "R", "N", "D",
When operated to the "2" and "1" positions, the force transmission portion 8 is displaced to the "R '", "N'", "D '", "2'" and "1 '" positions, respectively. As a result, the transmission connected to the force transmission unit 8 is driven.

Since the present invention has the above-described function, it has the following effects. That is, since the operation force of the shift knob is transmitted via the belt, the operation feeling is good, and the operation force of the shift knob can be set to an appropriate value by the gear mechanism to improve the operability. Further, the operation of the shift knob may be performed by means other than manual operation, for example, an electromagnetic actuator.
