Abstract: In a small massaging tool, numbness in fingers, strangeness, fatigue, and other discomfort, which are caused due to vibration of a grip part that is caused by vibration of a vibration motor, are eliminated to maintain comfortable use and vibration noise is reduced. The massaging tool includes a head unit 30 including vibrating parts 50 and 52 and a vibration motor 40 that vibrates the vibrating parts, a battery that is a power source of the vibration motor, and a body 10 having the vibration motor and the battery accommodated therein and having the grip part, wherein the head unit is supported in a floating state with respect to the body by a cushioning member made of gel-like resin and fixed to the body.

Abstract: To provide a sperm collector driving device 100 that detachably holds a sperm collector 200 and rotates the sperm collector 200 in a state of being held, the sperm collector 200 including a core member 210 that is constituted of an elastic material and has an insertion void 214 for a penis provided therein and a container 202 (a container main unit 204) that is constituted of a hollow member having an opening 204b in a base end and having a ventilation hole 204c in a front portion, and accommodates the core member 210 in an internal space, the sperm collector driving device 100 including a holding unit 120 that detachably holds the sperm collector 200, and a driving mechanism DM that rotates the sperm collector 200 held by the holding unit 120 about an axis, and introduces a negative pressure into the container 202 via the ventilation hole 204c.

Abstract: The sperm collection device includes a core member having an insertion hole for a penis and an insertion space, and a container having an internal space in which the core member is accommodated. The container includes a cylindrical base unit having a base end open in an axial direction of the base unit and attached to an insertion-hole-side end of the core member, and a cylindrical movable unit having a base end open in an axial direction of the movable unit and a front end being closed, and attached rotatably around an axis of the movable unit with respect to the other end of the base unit. In an overlapping part in which the base end of the movable unit overlaps the other end of the base unit, an airflow path and an adjustment mechanism are provided.

Abstract: To include a rotating holder 30 that is rotatably arranged in an opening of a casing 10 and detachably holds a part of a sperm sampler, a motor 50 that rotates and drives the rotating holder, a control unit 60, a battery 70, a single switch 20, 67, and an angular speed sensor 61 that detects an angular speed of the casing 10, where the control unit changes a rotation direction and a rotation speed of the motor according to a change in a turning angle of the casing 10.
