However, when configured as described above, the face wearability can be improved by adjusting the nose belt in a stepless manner with the shape memory resin, and it can be adjusted and stopped tightly to prevent the ingress of water. In addition, the wearing feeling of the swimming goggles can be improved and fixed securely.
(5) The nose belt may be heated to adjust the distance to a Shore D hardness of about 25 to 35, and cooled to use the Shore D hardness of about 70 to 80.
[0014]
With this configuration, the shore D hardness is about 25 to 35 when adjusting by heating the nose belt, and the operability when bending by hand is excellent, and the shore D hardness is about 70 to 80 when used. Therefore, when the belt is attached to the head, the nose belt is not easily deformed by the tension.
[0015]
In addition, the cushioning material for the face with respect to the eye cup may or may not be provided.
In swimming goggles for competitive swimming, a soft cushioning material is not attached to secure the face.
(6) It is good also as a thing which is not provided with the cushioning material to the face with respect to an eyecup.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
As shown in FIGS. 1 to 6, the swimming goggles of this embodiment include an eye cup 1 for protecting eyes.
