BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operating device for an automatic transmission, and more particularly to a shift operating device for an automatic transmission for a vehicle having a shift lock mechanism.

[0002]

2. Description of the Related Art Conventionally, in a shift operating device for an automatic transmission,
For example, a shift lock mechanism is provided so that the select lever can switch from the parking position to another range position only when the brake pedal is depressed when the vehicle starts. Further, it is preferable to prevent not only the switching operation from the parking position to another range position but also the switching operation from the neutral position to the reverse position during traveling.

The shift lock mechanism of the gear shift operating device for preventing the switching operation at such two positions generally has a lock member at each position, and each lock member is operated under a predetermined condition to operate the select lever. Is configured to block.

However, since the two lock members are operated under respective conditions, the number of parts for that is large, the structure is complicated, and the number of assembling steps at the time of assembling the shift lock mechanism is increased to increase the manufacturing cost. It becomes a factor.

Therefore, as disclosed in, for example, Japanese Unexamined Patent Publication No. 8-334167, the switching operation from the parking position to another range position and the switching operation from the neutral position to the reverse position are performed by a single lock member. A shift operation device for an automatic transmission has been proposed which includes a shift lock mechanism that blocks under certain conditions.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to the gear shift operation device disclosed in Japanese Patent No. 167, the select lever 105 is moved from the parking position P to another position by rotating the lock member 110 to an operating position where the engaging projection 106 protruding from the select lever 105 can abut. The switching operation to the range position and the switching operation from the neutral position N to the reverse position R can be effectively prevented. Further, the switching operation is permitted by rotating the lock member 110 to the non-operating position.

However, the lock member 110 supported by the support shaft 109 is brought into contact with the tip end surface of the engaging projection 106 of the select lever 105 to switch the parking position P to the parking disengagement position P1 and reverse from the neutral position N. Since the lock member 110 is rotated between the operating position that prevents the switching operation to the preparation position R1 and the non-operating position that avoids the contact, the lock member 110 becomes long and a large occupied space required for the operation is required. become.

The operation load of the select lever 105 swinging from the parking position P to the parking disengagement position P1 or from the neutral position N to the reverse preparation position R1 is substantially in the extending direction of the lock member 110 near the tip of the lock member 110. Since they act in the orthogonal direction, the load burden acting on the support shaft 109 that supports the lock member 110 and the shaft support portion of the support body 101 is large,
There is a concern that the durability may deteriorate due to wear of the part,
In order to receive this load, it is required to take measures such as supporting the support shaft 109 by straddling the support shafts 109 between the separated side portions of the support body 101.

As a result, since the relatively long support shaft 109 is arranged so as to extend between both sides of the support body 101, the space occupied by the shift lock mechanism becomes large, which inevitably leads to an increase in the size of the gear shift operating device. There is a concern that the gear shift operation device may increase in weight and manufacturing cost.

Further, it is extremely difficult to apply the present invention to a straight type speed change operation device in which a select lever is linearly rotated in the front-rear direction to perform a switching operation.

Therefore, an object of the present invention made in view of the above point is that it is possible to reliably prevent an improper select operation, has excellent durability, and is compact, and suppresses an increase in weight and an increase in manufacturing cost. (EN) It is possible to provide a straight type speed change operation device that can be performed.
