(One embodiment)
As shown in FIGS. 1 and 2, the continuously variable automatic transmission 1 for an electric vehicle according to the present embodiment includes a brake disk 2, a fitting member 3, a first lever 33, a second lever 34, a first elastic part 4, A second elastic part 5 and an operation member 6 are provided.
A continuously variable automatic transmission 1 for an electric vehicle has a transmission shaft 11.
The brake disk 2 is connected to the transmission shaft 11 and has a fitting portion on the brake disk 2.
In the present embodiment, the fitting portion is located in one or more fitting recesses 21 on the periphery of the brake disk 2.

The fitting member 3 has a shaft member 31.
The fitting block 32 is pivotally connected to the shaft member 31. The fitting block 32 has a fitting projection 321 on the fitting block 32 and corresponds to the fitting recess 21 on the brake disk 2.
In addition, the fitting convex portion 321 corresponds to the fitting concave portion 21 from the radial direction of the brake disk 2.
The width of the fitting concave portion 21 is larger than the width of the fitting convex portion 321.
The first lever 33 has a rotation center 331, is opposed to the rotation center 331, and has a first arm 332 and a second arm 333.
One end of the second lever 34 pivots on the second arm 333, and the other end pivots on the fitting block 32.

  The first elastic part 4 is installed on the fitting member 3.

The second elastic part 5 is installed on the fitting member 3.
In the present embodiment, the first elastic part 4 and the second elastic part 5 are torque springs.

  The operation member 6 is connected to the first arm 332 of the first lever 33.

As shown in FIGS. 1 and 2, when the electric vehicle is stopped, the fitting convex portion 321 of the fitting block 32 is fitted in correspondence with the fitting concave portion 21 on the brake disk 2.
As a result, the transmission shaft 11 of the continuously variable automatic transmission 1 of the electric vehicle becomes non-rotatable, and the tire of the electric vehicle becomes non-rotatable.
Thus, it is possible to avoid a situation in which the electric vehicle easily slides due to an external force action. At this time, the first elastic part 4 stores elastic potential energy.

As shown in FIGS. 1 and 3, when starting the electric vehicle, the operation member 6 is operated, and the operation member 6 interlocks the first arm 332 of the first lever 33, whereby the first lever 33 is rotated at the center of rotation. Rotates relative to 331.
At this time, the second arm 333 of the first lever 33 is interlocked, and the rotation of the second lever 34 is interlocked.
Thus, the second lever 34 rotates the shaft member 31 around the fitting block 32 in conjunction with the second lever 34.

Thus, the fitting convex portion 321 is released from the fitting concave portion 21 of the brake disk 2, the transmission shaft 11 of the continuously variable automatic transmission 1 of the electric vehicle rotates, and the electric vehicle tire is interlocked to Is activated.
When releasing the fitting, the first elastic part 4 releases the elastic potential energy.
Thereby, the fitting convex part 321 reliably separates from the fitting concave part 21 of the brake disk 2 to ensure the safety of traveling, and the second elastic part 5 stores elastic potential energy.

When the electric vehicle is parked, the operation member 6 is released, and the second elastic part 5 releases elastic potential energy.
Thereby, the fitting member 3 operates in the opposite direction, and the fitting convex portion 321 is fitted into the fitting concave portion 21 again.
Since the width of the fitting concave portion 21 is larger than the width of the fitting convex portion 321, the fitting convex portion 321 is engaged with the fitting concave portion 21 relatively easily.
In this structure, even if the fitting convex portion 321 moves in the fitting concave portion 21, if the movement angle of the fitting convex portion 321 at the fitting concave portion 21 is good, the electric vehicle moving distance is detected by the human body. It is hard to be done.

As shown in FIG. 4, in another type of brake disc 2A, the brake disc 2A has one or more fitting recesses 21A.
The width of the fitting concave portion 21A is substantially equivalent to the width of the fitting convex portion 321 described above.
In practice, the fitting convex portion 321 does not move in the fitting concave portion 21A, so that the tire of the electric vehicle can be fitted more firmly.

As shown in FIG. 5, the brake disc 2B of another type has one or more fitting holes 21B on the axial direction of the brake disc 2A.
The above-mentioned fitting convex part 321 can be fitted into the fitting hole 21B from above in the axial direction.
