Device for preventing reverse input and steering device for preventing reverse input

A steering device, comprising:

• a member;
• a motor connected to the member;
• a controller connected to the member and configured to control the motor;
• and
• a device connected to the motor and configured to prevent a reverse input,
• wherein the device connected to the motor and configured to prevent the reverse input comprises:
• a first housing;
• a second housing coupled with the first housing to define an internal space along with the first housing;
• an output shaft comprising an output disk disposed in the internal space and having one or more concave curved surfaces on an outer circumference surface of the output disk and an output shaft body configured to protrude from the output disk;
• an input shaft comprising an input disk having one or more concave grooves on an outer circumference surface thereof and an input shaft body disposed on a same rotation axis as a rotation axis of the output shaft body and configured to protrude from the input disk;
• and
• one or more moving pins disposed on the concave grooves, respectively, and configured to come into contact with the concave curved surfaces, respectively.

• and
• one or more moving pins disposed on the concave grooves, respectively, and configured to come into contact with the concave curved surfaces, respectively,
• wherein when rotatory power is input to the output shaft, rotatory power of the one or more concave curved surfaces of the output disk pressurizes the one or more moving pins toward an inner circumference surface of the first housing or an inner circumference surface of the second housing.
