1. A sperm collector driving device that detachably holds a sperm collector and rotates the sperm collector in a state of being held, the sperm collector including a core member that is constituted of an elastic material and has an insertion void for a penis provided therein and a container that is constituted of a hollow member having an opening in one end in an axial direction and having a ventilation hole in an other part in the axial direction, wherein the container accommodates the core member in an internal space thereof, the sperm collector driving device comprising:
a holding unit that detachably holds the sperm collector; and
a negative pressure-introduction and rotation unit configured to rotate the sperm collector held by the holding unit about an axis, and introduce a negative pressure into the container via the ventilation hole;
wherein
the negative pressure-introduction and rotation unit includes:
a motor,
a pump configured to generate the negative pressure,
a shaft configured to be rotated by the motor about an axis, wherein a channel within the shaft communicates between one end opening provided in one end of the shaft in the axial direction and an outer peripheral surface opening provided in an outer peripheral surface of the shaft, and
a bearing unit that rotatably supports the shaft and forms a pressure regulating space to which the negative pressure generated by the pump is introduced around the outer peripheral-surface opening, and
the holding unit includes:
a cup-shaped rotation holder to which the one end of the shaft is fixed, wherein the cup-shaped rotation holder is configured to rotate with the shaft and detachably hold the other part of the sperm collector, and
a holder-side packing that is attached on the cup-shaped rotation holder, wherein the holder-side packing communicates between the one end opening of the shaft and the ventilation hole of the sperm collector in an air-tight state when the rotation holder holds the other part of the sperm collector.
