PROBLEM TO BE SOLVED: To freely and finely adjust the rotation speed and rotation direction of a sperm sampling device by simply operating and adjusting the rotation direction posture (angle) of the device without performing complicated operation with a plurality of switches. Provided is a sperm sampling device driving device. SOLUTION: A rotary holder 30 rotatably arranged in an opening of a casing 10 and detachably holding a part of a sperm sampling device, a motor 50 for rotationally driving the rotary holder, a control means 60, and a battery 70. And a single switch 20, 67 and an angular velocity sensor 61 for detecting the rotational angular velocity of the casing, and the control means controls the rotational direction and rotational speed of the motor according to the change of the rotational angle of the casing. Change.
