2 is provided so as to protrude toward the inside of the base portion 7. The shaft rod body 22 is integrally formed with the bowl-shaped body 20, and the projecting axis line thereof coincides with the rotation axis line of the bowl-shaped body 20. The cover shaft hole 12
Are provided at a total of four positions corresponding to the pair of shaft rods 22 of each of the two bowl-shaped bodies 20, and the shaft rods 22 on one side of the two bowl-shaped bodies 20 are provided on both sides of the base portion 7. Two cover shaft holes 12, which are pivotally connected to each other, are provided adjacent to each other.

In the above structure, the punching hole 10 of the support board 6
By fitting the fitting piece 11 of the base portion 7 to the nipple 2, the nipple portion 2 is provided so as to project from the base body 3. Further, by pivotally attaching the shaft rod body 22 of the bowl-shaped body 20 to the cover shaft hole 12 of the base portion 7, the cover 4 can store or expose the nipple portion 2 in the base body 3.
Be pivoted to. That is, the cover 4 is a storage state in which both cups 20 are combined so that the mouth of the bivalve is closed so that the cover 4 completely covers the nipple portion 2, and each of the bowls 20 is stored so that the mouth of the bivalve is opened. It is possible to perform a pivoting operation between the position and an exposed state where the cover 4 is unfolded approximately 90 ° around the cover shaft hole to the outside orthogonal to the split surface and the cover 4 is exposed.

Next, the urging mechanism 25 has two bowl-shaped bodies 20.
4 projecting pieces 26, which are cam members projectingly provided on each of the pair of shaft rods 22 provided on the rotation fulcrums 21, and a pressing spring 27 made of a plate-shaped spring material that presses the projecting pieces 26.
And is configured. Each of the projecting pieces 26 is formed in a substantially rectangular shape, and is provided so as to project its longitudinal direction outward and in a direction orthogonal to the combined surface of the bowl-shaped bodies 20. The pressing spring 27 is formed in a substantially elliptic ring shape along the outer periphery of the rectangular wall 9 of the support board 6, and one long side is cut at the center. This pressure spring 27
Are assembled in the base body 3 such that the four shaft rod bodies 22 of the pair of bowl-shaped bodies 20 together with the respective protruding pieces 26 are constantly pressed against the back surface of the support board 12. The two adjacent protruding pieces 26 on one side of the bowl-shaped body 20 are individually pressed by two cut ends provided at the center of one long side of the pressing spring 27, and the two adjacent protruding pieces on the other side. 26 is a pressing spring 2

Therefore, since the pressing spring 27 presses the side portions of the projecting pieces 26 of the two bowl-shaped bodies 20 toward the support board 12, each of the bowl-shaped bodies 20 is rotated around the pivot axis. Power will always be applied. Therefore, the pair of bowl-shaped members 20, that is, the cover 4 is constantly urged by the pressing springs 27 via the respective protruding pieces 26 in the direction of closing their mouths so as to maintain the stored position.

In the lock mechanism 30, the cover 4 has a bowl-shaped body 20.
When the nipple portion 2 is exposed by widening the mouth of the bowl, the contact surface between each protruding piece 26 and the pressing spring 27 becomes a neutral state in which the rotational force around the pivot axis of the bowl 20 disappears. As described above, the shape and angle of each protruding piece 26 are set. As shown in FIG. 3, the protruding piece 26 is formed at an angle such that its protruding direction is orthogonal to the pressing direction of the pressing spring 27. The lock mechanism 30 allows the cover 4 to maintain its exposed state.

According to the above construction, the cover 4 for accommodating the nipple portion 2 is pivotally attached to the base body 3. Therefore, when not in use, the nipple portion 2 is accommodated in the cover 4 to prevent the nipple portion 2 from being contaminated. You can Further, the cover 4 and the base body 3 are not separated from each other regardless of whether they are used or not used.
Can be prevented from being lost.

Further, since the urging mechanism 25 is provided in the base body 3, when the cover 4 is located at a position other than the exposed position, the cover 4 is urged to the stored position so that the nipple 2
Can be stored. Therefore, it is possible to store the nipple portion 2 in the cover 4 while omitting the work of closing the mouth, and it is possible to prevent contamination of the nipple portion 2 more easily. In addition, since the lock mechanism 30 is provided in the base body 3,
The opening of the cover 4 can be opened wide to stop the biasing of the cover 4 in the storage direction, and the cover 4 can be maintained in the exposed state. Therefore, when using the pacifier, it is possible to eliminate unpleasant contact with the face by the cover 4 and the like, and a good feeling of use can be obtained.

In addition, since the lock mechanism 30 and the urging mechanism 25 are provided together in the base body 3, when the cover 4 is located at the exposed position, a force larger than that for maintaining the neutral state is obtained. If it is momentarily applied in the rotation direction around the axis of the bowl-shaped body 20, as shown in FIG. 4, the exposed state by the lock mechanism 30 is released, and the nipple 2 is moved by the urging mechanism 25.
It is possible to switch to a storage state in which the cover 4 is stored.
For example, even when the pacifier 1 is exposed and dropped on an unsanitary place such as a floor during use, the nipple 2 is housed in the cover 4 due to the impact to prevent the contamination more reliably. Is possible.

FIG. 5 shows another embodiment of the lock mechanism 30. The lock mechanism 31 is provided on both sides 2 of the pressing spring 27.
It is configured by including a bent portion 29 provided in each of the vicinity of 8 and a protruding piece 26 of the shaft rod body 22. Each protruding piece 2
6 is provided so as to project at an angle that engages with the bent portion 29 of the pressing spring 27 when the cover 4 is exposed. Therefore,
By engaging the protruding piece 26 and the bent portion 29, the bowl-shaped body 20
Is applied with a larger engaging force than the rotational force always applied in the storage direction, so that the exposed state of the cover 4 can be maintained and the bias in the storage direction can be stopped.
With this configuration, the exposed state of the cover 4 can be maintained more reliably.
