1. An ultrasound probe comprising:
a probe casing in which acoustic coupling liquid is sealed;
a motor fixed to the probe casing;
a first arm fixed to a first rotational shaft, and configured to rotate along with rotation of the first rotational shaft;
a protrusion provided to the first arm;
a first rotation transmission section attached to the first rotational shaft;
a second rotation transmission section engaged with the first rotation transmission section, and configured to rotate when the first rotation transmission section rotates in a direction opposite to a direction in which the first rotation transmission section rotates;
a second rotational shaft fixed to the second rotation transmission section, and configured to serve as a rotational shaft of the second rotation transmission section;
a second arm fixed to the second rotational shaft, and configured to rotate along with rotation of the second rotational shaft;
a third arm attached to the second arm such that the third arm is rotatable with respect to the second arm; and
an ultrasound device connected with the third arm, wherein:
the first arm, the second arm and the third arm are located in the probe casing;
the motor is connected with the first rotational shaft or the second rotational shaft;
the first rotational shaft or the second rotational shaft connected with the motor rotates along with rotation of the motor; and
the protrusion provided to the first arm is connected with the third arm such that the protrusion provided to the first arm is slidable along a longitudinal direction of the third arm.
