[Problems to be solved by the device]

 By the way, since the alarm sound is emitted into the water, it is attenuated in the water before it reaches the user. Further, the diving equipment 1 needs to downsize the alarm device 5 itself in response to a request for downsizing as a whole, and cannot output a high-power alarm sound. Therefore, the conventional alarm device 5 may miss the alarm sound, resulting in a very dangerous situation for the user.

In order to solve the above problems, an object of the present invention is to provide a diving equipment with an alarm device that surely transmits an alarm to a user by means other than an alarm sound.

[0006]

[Means for Solving the Problems] Means adopted by the present invention is a diving equipment with an alarm device, in which an alarm device is attached to a body of a diving device to which a mouthpiece is connected. Was established.

[0007]

[Action]

 When the vibration generator of the alarm device vibrates, the body of the diving equipment vibrates. This vibration is transmitted to the mouth of the user via the mouthpiece. This vibration is reliably transmitted to the user's mouth because the transmission medium is the body of the diving equipment and the mouthpiece.
