Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shift device for an automatic transmission used in the floor of an automobile.

[Prior Art and Problems to be Solved by the Present Invention] As a conventional shift device for an automatic transmission used in the floor of an automobile, there is, for example, one shown in Japanese Utility Model Application No. 60-131425.

However, according to such prior art, since the system uses a switch button to switch between parking range, reverse range, neutral range, drive range, 2nd speed and L speed range, it is necessary to switch between 2nd speed and 1st speed when climbing a steep slope. There is a risk of accidentally pressing the reverse range when switching to the fast range, so improvements are desired.

Therefore, according to the present invention, in view of such conventional problems, two
When switching to the 2nd and 1st speed ranges, the purpose is to enable switching to the 2nd and 1st speed ranges only when the drive range is in the drive range.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a shift device for an automatic transmission that includes a console box supported on a vehicle body, an elongated slide opening that covers the top opening of the eight console box, and two longitudinally elongated slide openings. a cover having a switch opening; a first lever protruding so as to be slidable back and forth within the slide opening of the cover; and a first lever supported so as to be swingable back and forth about a shaft portion with respect to the vehicle body; a second lever integrally extending downward and connected to a control rod of the automatic transmission; a third lever extending upward from the shaft portion and standing at a predetermined angle with respect to the first lever; A switch plate is pivotably supported to be vertically movable with respect to the vehicle body and is always urged downward by an urging means, and a changeover switch for 2nd speed and 1st speed supported by the switch plate; The second lever is connected to a third lever, the other of which is in contact with the lower part of the free end of the switch plate, and when the first lever is rotated to the drive position, the two switch openings of the cover are connected to the second gear; It is characterized by having a bell crank-shaped fourth lever that moves the switch plate upwardly against the urging force so that the first speed changeover switch protrudes.

[For production]

Since the present invention has such a configuration, its operation will be explained next.

When the first lever is rotated to the drive range, the third lever is moved simultaneously, and one of the fourth levers is lowered and the other is lifted, thereby pushing up the switch plate and shifting the second gear supported by the switch plate. , the first speed selector switch protrudes from the two switch openings in the cover, and both switches are kept pressable.

Therefore, even though the first lever is in the drive range, the second lever is in the drive range.
By pressing the selector switch for 1st and 1st speeds, the range can be changed to 2nd or 1st speeds.

At the same time, if you don't set the first lever to the drive range,
Since the switch for 2nd and 1st speeds cannot be operated, for example, when the 1st lever is in reverse range, 2nd and 1st speeds cannot be operated.
There is no possibility of accidentally switching to 1st speed.
