Description

Ejaculation stimulating device

Technical Field

The present invention relates to an ejaculation stimulating device, and more particularly, to an improvement of an ejaculation stimulating device used in the past based on social needs such as medical research, medical needs, sexual crime prevention, marketing prevention, and venereal disease transmission.

Background

Various ejaculation stimulating devices (sperm collecting devices) for collecting male sperm have been suggested for satisfying medical research and medical needs. For example, ejaculation stimulating devices are used for medical needs, such as detecting sexual function of husband with collected sperm to find out the cause of infertility of couples, treating sexual dysfunction, or retaining and storing sperm for artificial insemination, etc. Further, in order to satisfy various social needs such as prevention of sexual crime, prevention of selling, reduction of the number of infected persons by solving individual sexual desire, there has been also known a simple ejaculation stimulating device which is conventionally available at low price and does not cause problems in terms of hygiene or health since it is disposable or washable.

For example, patent document 1 (japanese unexamined patent application publication No. 2006-334176) discloses an ejaculation stimulating device. The ejaculation stimulating device comprises a cylindrical container made of relatively hard plastic and having one end opened in the longitudinal direction, and a gel-like resin core member, which is accommodated in the container and has an insertion space extending from an insertion opening at one end in the longitudinal direction to the inside.

However, in this ejaculation stimulating device, when the penis is inserted into the insertion space of the core member to inflate the core member, the internal pressure of the space formed between the core member and the container cannot be reduced to a predetermined value or less, and therefore, there is a limit to increase of the tightening force of the penis.

That is, the intensity of the stimulus suitable for promoting ejaculation varies between individuals, and both of the person who has a weak stimulus and the person who has no effect on the stimulus other than the strong stimulus are present. In order to obtain strong stimulation, it is effective to increase the adhesion (suction) of the core member to the tip (glans) of the penis. In order to increase the stimulation applied to the tip portion of the penis when rubbing the penis in the state where the penis is inserted into the insertion space, it is effective to reduce the internal pressure of the space formed between the core member and the container so as to increase the close contact force (adsorption force) between the tip portion of the penis and the core main body. However, in the structure of patent document 1, there is a limit to such pressure reduction (pressure adjustment).

Patent document 2 (japanese patent application laid-open No. 2015-112317) discloses an ejaculation stimulating device in which a plurality of slit-shaped through holes extending in a longitudinal direction are formed in an outer sheath that houses a cylindrical inner sheath having a male genital insertion portion, and a fastening ring body that is movable in the longitudinal direction along an outer surface of the outer sheath by manual operation is disposed while being expandable and contractible in inner and outer diameter directions, and the insertion pressure of the cylindrical inner sheath is changed by changing the diameter of the outer sheath by changing the position of the ring body in the longitudinal direction.

In this ejaculation stimulating device, the pressure to the cylindrical inner body is mechanically adjusted by the pressure from the annular body, without using a method of adjusting the air pressure between the outer body and the cylindrical inner body.

However, the operation of moving the ring body in the longitudinal direction of the outer package is not only troublesome, but it is also difficult to finely adjust the pressure applied to the penis by the cylindrical inner package in such a configuration. In particular, even if the annular body is moved to a position in the longitudinal direction of the exterior body corresponding to the front end portion of the inner wall of the cylindrical interior body in which the front end portion of the penis is located, the pressure applied from the annular body to the front end portion of the penis by the cylindrical interior body is constant, and the pressure cannot be arbitrarily increased or decreased.

(basic constitution)

The present invention will be described in detail below with reference to embodiments shown in the drawings.

Fig. 9(a) to (d) are a front view, a plan view, a longitudinal sectional view, and an open side perspective view of the operation portion. Further, fig. 10(a), (b) and (c) are a partial sectional view and an X-X sectional view showing a state where the inner cover housed in the container main body holds the pressing member, and a partial sectional view showing a relationship between the operation portion and the movable portion of the pressing member. Fig. 11(a) and (b) are perspective views showing the state before and after deformation of the pressing member.

Note that in this specification, for convenience of explanation, the lower side of fig. 1 is referred to as a front end side (front), and the upper side is referred to as a rear end side (rear).

The ejaculation stimulating device 1 comprises a container (container body 11, cover 20)10 having an opening 11a at least in part; an inner closure 40 installed in a container body 11 constituting the container 10 and configured to be non-rotatable with respect to the container body; an operation unit 60 configured to be rotatable with respect to the container body; a core member 80 housed in the container body and having an insertion space 84 extending inward from an insertion port 82 located on the opening 11a side; and an (elastic) pressing member (elastic deformation member) 100 that is activated (elastically deformed) by a rotational operation of the operation portion 60 to change the pressing force applied to the core member 80.

The container 10 is made of resin produced by blow molding, and includes a hollow substantially cylindrical (drum-shaped) container body 11, and a lid 20 provided at an opening portion 11a at one end (rear end) of the container body to open and close the opening portion. The container body 11 is a hollow cylindrical body penetrating in the axial direction, and has

openings

11a and 11b at both ends in the axial direction.

The inner cover 40 is a hollow substantially cylindrical body made of resin produced by injection molding and penetrating in the axial direction, and accommodates the pressure member 100 therein. As for the inner closure 40, a shape including a diameter and an axial length thereof is set such that the inner closure 40 can be accommodated in the container body 11. By fitting the locking recesses 46 as square holes into the locking projections 114, the inner cover 40 of the present example is locked immovably in both the axial direction and the circumferential direction. And is positioned and fixed in the container body by the pressurizing member 100 located at the inner side thereof. That is, since the one end portion (rear end portion) of the inner cover 40 is locked to the outer surface of the one end portion of the pressing member 100 so as to be unrotatable and immovable in the axial direction, the one end portion of the pressing member 100 is locked to the one end portion of the container body so as to be unrotatable and immovable in the axial direction, whereby the inner cover 40 can be locked to the container body. It should be noted that this is only one embodiment, and it is also possible to directly latch the inner closure with respect to the container body.

The inner cover 40 and the pressing member 100 are collectively referred to as an inner unit.

The inner unit is detachable from the container body, and is accommodated by fitting a tongue-shaped locking piece 42 provided at one end of the inner cover 40 into a part of the container body, and is fixed to such an extent that it does not come off when used, and can be pulled out by applying a certain load. Thus, the internal unit can be taken out and cleaned independently.

A plurality of rectangular locking holes 43 formed to penetrate at a predetermined pitch in the circumferential direction and 2 elongated guide long holes 45 provided in parallel with the row of locking holes and extending in the circumferential direction are provided near the other end (front end) of the inner cover 40. Each of the short locking holes 43 is a positioning means for locking the pressing member 100 disposed inside at a predetermined rotation angle, and the long guide hole 45 is a guide means for stably rotating the pressing member along a predetermined track, and also has a stopper function to prevent the pressing member 100 from being contracted in the axial direction and to have a small clearance. The 2 guide long holes 45 are arranged in the vicinity of the other end of the inner cover in a line-symmetrical positional relationship with respect to the center axis of the inner cover.

The operation unit 60 is attached to close the other end opening (front end opening) 11b of the container body, and includes a lid (bowl) -shaped operation member 61, and the operation member 61 is supported to be rotatable about the axis of the container body and to be manually operable. The operation member 61 is assembled so as not to fall off the container body by slidably engaging the convex portion 12 provided on the outer peripheral surface of the container body with the groove portion 62 provided in the circumferential direction on the inner peripheral surface close to the opening of the operation member 61 (fig. 10(a) (c)). Further, the plurality of projections 13a projecting from the outer peripheral surface of the other end portion of the container main body are configured to be engageable with the plurality of projections 63 provided on the corresponding inner peripheral surface of the operation member 61, thereby restricting the range of rotation of the operation member with respect to the container main body (fig. 10 (b)).

In the present example, the operating portion 60 is freely rotatably supported by the container body, but this is just one example, and the operating portion may also freely rotate relative to the container body.

As shown in fig. 9, a gas discharge hole 64 is formed through the center of the inner bottom surface of the operation member 61, and a plurality of thin plate-

like ribs

65a, 65b are provided so as to protrude at a predetermined circumferential pitch in a plurality of groups on the inner wall of the operation member, one rib 65a is more elongated (has a large protruding length toward the inner diameter side) on the inner diameter side than the other rib 65b, and the inner diameter side end portion of each elongated rib 65a is configured so as to be fitted into and positioned in a valley portion 122b of the movable portion 120 provided on the front end side of the pressing member 100. That is, the elongated rib 65a is a means for determining the circumferential position of the movable part 120 and fixing the movable part so as not to rotate relative to the operation member. Each short rib 65b is a means for contacting the outer peripheral surface of the movable portion 120 (the outer peripheral surface of the ridge portion 122 a) to determine the radial position of the movable portion 120. That is, each short rib 65b is a means for preventing the inner diameter and outer diameter positions (positions of the outer peripheral surface) of the movable portion from being deviated in the circumferential direction. In other words, each short rib 65b is a means for maintaining the shape of the movable portion 120 in the operation member 61 in a substantially cylindrical shape.

The core member 80 is made of gel-like resin such as elastomer, and is substantially provided with a core main body 81 having an insertion port 82 and an insertion space 84, and a flange 86 provided to protrude from the outer periphery of the core main body 81 on the insertion port 82 side. The outer periphery of the core body 81 has a plurality of 1 st ribs 81a which are protrudingly provided at the outer peripheral end edge with a desired interval and spirally extend in substantially the same direction (substantially parallel) to each other; and a plurality of 2 nd ribs 81b protrudingly provided on an outer circumferential surface of the core main body at a desired interval and crossing the 1 st ribs 81 a.

It should be noted that the shape of the

ribs

81a, 81b extending spirally on the outer periphery of the core main body 81 is only an example, and is not limited to this shape and structure.

The pressing member 100 is disposed in a gap between the inner surface of the inner cover 40 and the outer surface of the core member 80, and has one end outer periphery thereof locked by the corresponding one end inner periphery of the container body 11, and locked portions 122 (mountain portions 122a, valley portions 122b) provided at the other end edge (movable portion 120) thereof are locked and held by ribs (locking portions) 65a, 65b provided at the inner surface of the operating member 61, so that the other end thereof is fixed to the operating member. The pressing member 100 includes an elastic deformation portion 101 that changes a pressure applied to an outer peripheral surface of the core member located inside by elastically deforming in the inner and outer diameter directions. In this example, the elastic deformation portion 101 has a configuration (spiral member) in which an elastic band-shaped resin plate (thin plate-shaped elastic member) 101a is molded into a spiral cylindrical shape, and maintains an original shape when an external force in a twisting direction is not applied, but reduces its diameter by applying a twist in a contracting direction. The annular fixed portion 110 to which the inner cover 40 is locked (fixed) is integrated with one axial end of the elastic deformation portion 101, and the movable portion 120 including the locked portion 122 is integrated with the other axial end.

The engaged portion 122 provided in the movable portion 120 is composed of the peak portions 122a and the trough portions (slits) 122b alternately provided at a predetermined circumferential pitch, and as described above, the movable portion 120 is brought into a state of being rotatable integrally with the operation member 61 by fitting the ribs 65a into the respective trough portions 122 b.

A plurality of locking projections 111 are provided on the outer peripheral surface of the fixed part 110 so as to project with a predetermined gap in the circumferential direction, and a plurality of locked parts 15 provided on the inner peripheral surface of the corresponding one end of the container body so as to project are fitted between the gaps (elastically fitted), whereby the fixed part 110 is supported so as to be immovable in the rotational direction with respect to the container body. The plurality of locking projections 111 are arranged at predetermined intervals in the circumferential direction, and the interval of the gap between the ends of the locking projections is set to allow the locked portion 15 to be fitted in the gap. That is, when the front end portion of the pressing member 100 in which the inner cover is assembled is inserted into the one end opening 11a of the container body 11 and assembled, the engaged portion 15 on the container body side is fitted into the space between the locking ribs 111, whereby the engaged portion can be fitted between the ends of the locking ribs (into the space), and the inner cover is converted into a state in which it cannot rotate relative to the container body.

As shown in fig. 1(a), 9, and the like, a plurality of scales 67 are formed at a predetermined circumferential pitch on the outer peripheral surface of the operation member 61, and a mark 17 is added to a position along the other end edge of the container body 11 so that the rotation angle of the operation member can be determined when the operation member 61 is rotated relative to the container body. The pitch between the respective scales 67 coincides with the pitch of the respective locking holes 43 formed near the other end (front end) of the inner cover 40, and when a locking protrusion 123 described later provided to the pressing member 100 is fitted to any one of the locking holes 43, the positional relationship is set such that the marks 17 are one-to-one opposed to one of the scales 67 corresponding to the locking hole 43. That is, by checking the position of the scale 67 in the positional relationship corresponding to the mark 17, the relative rotational angle of the operating member 61 with respect to the container body 11 can be visually checked (the relative rotational angle of the movable portion 120 of the pressing member with respect to the container body is the amount of twisting of the elastically deforming portion 101 of the pressing member which is the amount of pressing force applied to the core member).

In a state where the fixed portion 110 is fixed to the inner cover 40, the pressing member 100 rotates the movable portion 120 by the operating member 61, so that at least a part of the elastic deformation portion 101 is elastically deformed in the inner and outer diameter directions to change the pressing force applied to the core member. The elastic deformation portion 101 is not able to expand and contract in the axial direction, but adjusts the pressure applied to the core member by deforming in the inner and outer diameter directions.

The O-ring 140 shown in fig. 1(b), 3 and 4 is fitted into a recess near the other end of the container body, and maintains airtightness between the opening-side end of the operating member 61 disposed outside the O-ring.

Next, a structure in which the pressing member 100 is assembled to the inner cover 40 will be described.

The pressing member 100 is mounted inside from an opening at one end (rear end) of the inner cover 40, and in a state where the mounting is completed, as shown in fig. 1 and 10, the fixed portion 110 having a large diameter is located (projected) rearward of one end edge of the inner cover. In this state, the locking recess 46 (fig. 7 a) provided at one end of the inner cover 40 is fitted into the locking projection 114 (fig. 8 a), whereby the relative movement of the pressing member 110 in the circumferential direction and the axial direction is restricted. Further, the relative movement in the axial direction is also restricted by the frictional resistance between the outer peripheral surface of the fixed portion 110 of the pressing member and the inner peripheral surface of the one end opening portion of the inner cover.

A slide projection 121 projecting from the outer surface of the movable portion 120 of the pressing member is fitted into a guide long hole 45 formed through the other end (front end) of the inner cover 40 so as to be slidable in the circumferential direction. By fitting the slide projection 121 into the guide long hole 45, the movable portion 120 can be rotationally moved on a stable orbit with respect to the inner cover. Further, a locking protrusion 123 to be fitted into any one of the locking holes 43 is provided to protrude from an outer surface of the movable portion 120 corresponding to the arrangement direction of the locking holes 43.

As shown in fig. 11, the sliding protrusion 121 and the locking protrusion 123 are protrusions provided in an elastic deformation portion in which two parallel notches are formed at appropriate positions of the annular movable portion 120 formed of a resin plate material, and rectangular portions between the notches are elastically deformable in the inner and outer diameter directions. When a force in the direction of rotating the operating member 61 (movable portion 120) is applied with a predetermined or more force while the locking protrusion 123 is fitted in any of the locking holes 43 with a constant fitting force, it is elastically deformed (retracted) in the inner diameter direction so as to be disengaged from the locking hole 43 and can move and fit into another adjacent locking hole 43.

The locking projection 123 has a projection length that can maintain the fitted state in the state fitted in the locking hole 43. On the other hand, the shape, frictional resistance, and the like of the locking projection 123 are selected so that, when a force of a predetermined amount or more is applied in the rotational direction, the locking projection is retracted in the inner diameter direction, is disengaged from the locking hole 43 fitted so far, and is movable into the adjacent locking hole.

According to the present invention, the operating member 61 is rotated by manual operation to increase or decrease the pressure applied to the outer surface of the core member 80 by the pressurizing member 100, so that stimulation and tightening force with a large variation in appropriate pressure can be applied to the penis (the whole penis, not only the tip portion) positioned inside the core member.

Fig. 17(a), (b) and (c) are a partial sectional view and an X-X sectional view showing a state where the container main body holds the pressing member, and a partial sectional view showing a relationship between the operation portion and the pressing member.

Note that in this specification, for convenience of explanation, the lower side of fig. 12 is referred to as the front end side (front), and the upper side is referred to as the rear end side (rear).

The ejaculation stimulating device 1 comprises a container (container body 11, cover 20)10 having an opening 11a at least in part; an operation unit 60 configured to be rotatable with respect to the container body; a core member 80 housed in the container body and having an insertion space 84 extending inward from an insertion port 82 located on the opening 11a side; and an (elastic) pressing member (elastic deformation member) 100 that is activated (elastically deformed) by a rotational operation of the operation portion 60 to change the pressing force applied to the core member 80.

The constitution of the container 10 and the core member 80 is basically the same as that of embodiment 1, and therefore the same portions are given the same reference numerals, and the description of the repetitive constitution is omitted.

The operation unit 60 is attached to close the other end opening (front end opening) 11b of the container body, and includes a lid (bowl) -shaped operation member 61, and the operation member 61 is supported to be rotatable about the axis of the container body and to be manually operable. The operation member 61 is assembled so as to be inseparable and freely rotatable with respect to the container body by slidably engaging the convex portions 12 provided at the respective outer peripheral surfaces of the container body in the groove portions 62 provided in the circumferential direction on the inner peripheral surface close to the opening portion of the operation member 61 (fig. 12(b) — that is, the operation member 61 is supported so as to freely rotate with respect to the front end side of the container body without changing the axial position.

As shown in fig. 12(b), an air vent hole 64 is formed through the center of the inner bottom surface of the operating member 61, and a female screw portion (screw portion) 71 is formed on the inner wall of a sleeve 70 projecting from the inner wall of the operating member.

The pressing member 100 is disposed in a gap between the inner surface of the container body 11 and the outer surface of the core member 80, one end outer circumference thereof is locked by the corresponding end inner circumference of the container body 11, and an external thread portion (thread portion) 125 provided at the other end edge (movable portion 120) is threadedly engaged with an internal thread portion 71 provided at the inner surface of the operating member 61. That is, the pressurizing member 100 includes a fixed portion 110 which is provided near the rear end and is non-rotatably locked to the container body 11; a movable portion 120 provided near the distal end and having a male screw portion 125 screwed into the female screw portion 71 of the operating member 61; and an elastic deformation portion 101 whose both end portions are integrally formed with the fixed portion 110 and the movable portion 120, respectively. When the operating member 61, whose axial position does not change even when rotated, is rotated forward and backward, the movable portion 120 is retracted in the axial direction by the male screw 125 screwed into the female screw 71, and therefore the elastic deformation portion 101 is elastically deformed in the inner and outer radial directions.

That is, the pressing member 100 includes an elastic deformation portion 101 that changes the pressure applied to the outer peripheral surface of the core member located inside by elastically deforming in the inner and outer diameter directions. In this example, the elastic deformation portion 101 has a configuration (spiral member) in which an elastic band-shaped resin plate (thin plate-shaped elastic member) 101a is formed into a spiral cylindrical shape, and maintains an original shape when no external force in a twisting direction is applied, but reduces its diameter (deforms in a pressing direction) by applying twisting in a contracting direction. An annular fixed portion 110 to be locked (fixed) by the container body is integrally formed at one axial end of the elastic deformation portion 101, and a movable portion 120 having an external thread portion 125 is integrally formed at the other axial end.

It should be noted that by making the inclination of each of the threaded portions of the internal threaded portion 71 and the external threaded portion 125 gentle to narrow the pitch, the frictional resistance generated between the thread teeth can be increased when the operating member 61 is rotated in the circumferential direction. Therefore, the operating member can be held at an arbitrary circumferential position (rotational direction angle with respect to the container body) without particularly providing a lock mechanism, and the tightening force from the pressing member corresponding to the circumferential position of the operating member can be adjusted steplessly.

It should be noted that the screw portion on the operation portion side may be an external screw portion, and the screw portion on the movable portion side may be an internal screw portion.

A plurality of locking projections 111 are provided on the outer peripheral surface of the fixed portion 110 so as to project with a predetermined gap in the circumferential direction, and a plurality of locked portions 15 provided on the inner peripheral surface of one end of the container body so as to project are fitted into the gaps, whereby the fixed portion 110 is supported so as to be immovable in the rotational direction with respect to the container body. The plurality of locking projections 111 are arranged at predetermined intervals in the circumferential direction, and the interval of the gap between the ends of the locking projections is set to allow the locked portion 15 to be fitted in the gap. That is, when the distal end portion of the pressing member 100 is inserted into the one end opening 11a of the container body 11 and assembled, the engaged portion 15 on the container body side is fitted into the space between the locking ribs 111, whereby the engaged portion can be fitted between the ends of the locking ribs (into the space) and can be shifted to a state in which the engaged portion cannot be displaced in the rotational direction with respect to the container body.

In the above configuration, as shown in fig. 17(c), when the operating member 61 is rotated in one direction R1, this rotational force is transmitted from the female screw portion 71 to the male screw portion 125, and the movable portion 120 moves in the axial direction AD1 (extending direction), so that the elastic deformation portion 101 is reduced in diameter while being extended, thereby pressing the outer peripheral surface of the core member 81 inward. On the other hand, when the operating member 61 is rotated in one direction R2, this rotational force is transmitted from the internal thread portion 71 to the external thread portion 125, and the movable portion 120 is moved in the axial direction AD2 (shortening direction), so that the elastically deforming portion 101 expands in diameter while shortening, thereby weakening the pressure applied to the outer peripheral surface of the core member 81.

< embodiment 3 >

(basic constitution)

Fig. 18(a) and (b) are a front view and a longitudinal sectional view showing an external configuration of a ejaculation stimulating device (sperm collecting device) according to embodiment 3 of the present invention. Fig. 19 is an exploded perspective view showing each component of the ejaculation stimulating device. Fig. 20 is an exploded front view showing each component of the ejaculation stimulating device. Fig. 21(a), (b) and (c) are vertical sectional views showing the starting sequence of the pressing member associated with the operation of the ejaculation stimulating device.

Note that in this specification, for convenience of explanation, the lower side of fig. 18 is referred to as the front end side (front), and the upper side is referred to as the rear end side (rear).

The ejaculation stimulating device 1 comprises a container (container body 30, cover 35)10 having an opening 30a at least in part; an operation unit 150 configured to be rotatable with respect to the container body 30; a core member 80 housed in the container body and having an insertion space 84 extending inward from an insertion port 82 located on the opening 30a side; and an (elastic) pressing member (elastic deformation member) 200 that is activated (elastically deformed) by a rotational operation of the operation portion 150 to change the pressing force applied to the core member 80.

The container 10 comprises a container body 30, in which a core member 80 and a pressurizing member 200 are accommodated; and a lid 35 for closing the opening 30a of the container body 30 (via the operation portion 150).

Note that, in a state where the lid 35 is fixed to the opening portion 30a side of the container main body, only the operation portion 150 may be freely rotated with respect to the container main body and the lid, or the lid and the operation portion may be freely rotated with respect to the container main body together in a state where the operation portion 150 is locked to the lid 35.

The configuration of the core member 80 is basically the same as that of the 1 st and 2 nd embodiments, and therefore the same portions are given the same reference numerals, and a description of the repetitive configuration is omitted.

The operation unit 150 includes an operation member 151 formed of an annular body, which is disposed so as to be rotatable with respect to the outer periphery of the one end opening (rear end opening) 11b of the container main body, and is a manually operated dial supported so as to be rotatable about the axis of the container main body. The operating member 151 is supported by the container body such that the axial position with respect to the container body does not change greatly when the operating member 151 rotates.

The operating member 151 has an annular cam portion 155 (fig. 21) integrally provided concentrically inside thereof, and the cam portion 155 is configured to engage (slide) with a cam follower 205 provided to protrude from a rear end edge of the pressing member 200. By rotating the operation member 151 relative to the container body, the distance by which the cam portion 155 presses the cam follower in the axial direction is changed, so that the elastically deforming portion 215 of the pressing member is deformed (displaced) in the inner and outer radial directions.

The cam portion 155 has a structure in which a plurality of inclined surfaces 155a having a predetermined circumferential length are circumferentially continuously provided via a step portion 155 b. When the operating member 151 is rotated forward and backward, the tip end portion of the cam follower 205 of the pressing member moves forward and backward along the inclined surfaces, and the axial position of the cam follower can be changed.

The pressing member 200 is disposed in a non-rotating manner in the gap between the inner surface of the container body 30 and the outer surface of the core member 80 such that the plurality of cam followers 205 provided at one end are in free sliding contact with (or come close to) the inclined surface 155a of the cam portion 155 of the operation member 151 and the other end (the front end portion 210) is in contact with the inside of the front end of the container body. The pressing member 200 according to the present example is a substantially bag-shaped body having an open rear end and a closed front end portion 210. The cam followers 205 are projections having an arc shape at the front end protruding from the annular portion 202 provided at the rear end of the pressing member, and in this example, 4 cam followers 205 are protruding at intervals of 90 degrees.

The pressing member is made of a resin plate or a rubber plate having a hardness (shape retainability) not lower than a predetermined level and elasticity.

An elastic deformation portion 215 is integrally formed between the annular portion 202 and the distal end portion 210 of the pressing member. That is, the pressing member 200 includes an elastic deformation portion 215 that changes the pressure applied to the outer peripheral surface of the core member located inside by elastically deforming in the inner and outer diameter directions. The elastic deformation portion 215 according to the present example has a configuration in which a plurality of thin plate-like elastic members (elastic deformation members) 216 extending in the axial direction, which are substantially band-shaped resin plates having elasticity, are arranged at intervals (long holes 217) in the circumferential direction. Then, when the operation member 151 is rotated in one direction, the thin plate-like elastic member (elastic deformation member) is displaced (deformed) toward the inner diameter side (pressing direction), and when the operation member is rotated in the other direction, the thin plate-like elastic member is displaced toward the outer diameter side (non-pressing direction).

The thin plate-like elastic member 216 according to the present example has a configuration in which the axial intermediate portion 216a thereof is recessed further toward the inner diameter side than the axial both end portions without applying an external force. When a force that compresses the pressing member in the axial direction is applied, the intermediate portion 216a becomes more easily deformed in the inner radial direction.

In the above configuration, as shown in fig. 21 a, when the operating member 151 (cam portion 155) is rotated in one direction R1, the cam followers 205 are urged to move relative to the inclined surfaces 155a in the direction of the arrow D1, and therefore the entire annular portion 202 as the movable portion moves axially inward, and the thin plate-like elastic member 216 is compressed and deformed radially inward. Therefore, the thin plate-like elastic members 216 gradually press the outer peripheral surface of the core member 80 inward. On the other hand, when the operating member 151 (cam portion 155) is rotated in the other direction R2, since a force is applied to move the cam followers 205 relative to the inclined surfaces 155a in the direction opposite to the arrow D1, the annular portion 202 as a whole moves outward in the axial direction so as to deform the thin plate-like elastic member 216 toward the outer diameter side. Therefore, the force with which the thin plate-like elastic members 216 press the outer peripheral surface of the core member 81 inward gradually decreases.

As described above, the ejaculation stimulating device according to embodiment 3 is characterized in that the elastic deformation portion 215 includes a plurality of thin plate-like elastic members 216 extending in the axial direction and arranged at intervals in the circumferential direction (spaced apart), and when the operation portion is rotated in one direction, at least a part thereof is displaced in the inner radial direction, and when the operation portion is rotated in the other direction, at least a part thereof is displaced in the outer radial direction.

Therefore, by manually rotating the operation member 150 to increase or decrease the pressure applied by the pressurizing member 200 to the outer surface of the core member 80, stimulation and tightening force with a large variation in appropriate pressure can be applied to the penis (the whole penis, not only the tip portion) located inside the core member.
