界によって規定されることとなっていた。(c) Problems to be solved by the invention However, in the conventional automatic transmission oil suction device as described above, the suction port is fixedly set, so that sudden turning, starting, and stopping are not possible. When driving on a slope with a large inclination angle, the oil in the oil reservoir is affected by inertia and
Due to gravity, etc., the oil reservoir may be biased to one side, and air may be sucked in from the suction port. If air is sucked in from the intake port, the specified oil pressure will not be obtained.
Therefore, the limits of the turning performance of both vehicles and the limits of running performance on slopes were to be determined by the above-mentioned air intake limit.

所定の位置でつり合うようにしである。(F) Embodiment FIG. 1 shows an embodiment of the present invention. An oil reservoir 12 is attached to the lower part of the casing 10 of the automatic transmission, and the oil reservoir 12 is filled with a predetermined amount of oil. An oil strainer 16 is fixed to the lower part of the valve body 14 provided at the lower part of the casing 1o. The upper end of a flexible tube 18 is attached to the suction port 16a of the oil strainer 16 in a sealed manner. A ring-shaped weight 20 having a predetermined mass is attached to the lower end of the flexible tube 18. The flexible tube 18 is made of a thin metal plate and has a bulky shape, and the lower end thereof is movable in any direction relative to the upper end thereof. The elastic force of the flexible tube 18 and the weight of the weight 20 are balanced at a predetermined position.

防止される。Next, the operation of this embodiment will be explained. When a vehicle equipped with this automatic transmission turns at high speed, the oil in the oil reservoir 12 moves to one 11 in the oil reservoir 12 due to centrifugal force. The centrifugal force generated during turning also acts on the weight 20, and the weight 20 deforms the flexible tube 18 and moves in the same direction as the oil movement direction. The flexible tube 18 is configured in a bulky manner, and is bowed downward by the weight of the weight 20.
In order to extend the bow, the flexible tube 18 is moved laterally with the opening at the F end facing downward (that is, the flexible tube 18 becomes an inclined tube). This allows the flexible tube 18
The opening at the lower end of the cylinder moves in the same direction as the oil movement direction, so that it is always submerged in oil and air is prevented from being sucked in.

ューブ１８の下端部の移動方向が前後方向となり、同様
の作用を得ることがてきる。Furthermore, when driving on a slope with a large inclination angle, the direction of oil movement is the front-back direction, and accordingly, the direction of movement of the lower end of the flexible tube 18 is the front-back direction, making it possible to obtain the same effect. .
急制動時及び急加速時についても同様である。The same applies to sudden braking and sudden acceleration.

■児ル：目１塾匂することはなくなる。Therefore, in all driving conditions of the vehicle, the ability to suck in air is eliminated, and the automatic transmission prevents the vehicle from drawing air.
■Chiru: First, you won't have to worry about cram school anymore.

However, it is possible to prevent the automatic transmission from restricting the driving performance of the vehicle.
