  As shown in FIG. 2, the oxygen cylinder 7 is inserted into the storage pocket 61, and the neck portion 71 or the regulator body 81 is fixed by a fixing band 64. Then, the storage pocket 61 is covered with the pocket cover 62, and the pocket cover 62 is fixed with the hook-and-loop fastener 622 and the hook-and-loop fastener 16 of the jacket main body 1. Then, the oxygen cylinder 7 is attached to the jacket main body 1 by covering the oxygen cylinder 7 head with a bag-shaped cylinder head cover 63.

  A regulator main body 81 integrated with an indicator, an on-off valve and the like is detachably provided on the head of the oxygen cylinder 7. The regulator main body 81 and the mouthpiece 82 are connected by a high-pressure hose 83. The high pressure hose 83 descends in the pocket cover 62, extends from the open side 621 at the bottom of the pocket cover 62 to the outside of the oxygen cylinder storage portion 6, and guides 111 for guiding the high pressure hose 83 at the skirt portion of the body 1. It is guided by a guide 112 provided on the end side of the left front body 11 and is connected to a mouthpiece 82 that is detachably stored near the neck of the left front body 11. In this way, by extending the high-pressure hose outward from the open side 621 at the bottom and guiding it to the vicinity of the neck of the left front body 11, the high-pressure hose 83 does not get in the way during operations such as steering.

  Here, the regulator main body 81, the high-pressure hose 83, and the mouthpiece 82 constitute a regulator. The regulator and the oxygen cylinder 7 constitute an emergency breathing apparatus section.

  The mouthpiece 82 is detachably fixed by a mouthpiece cover 84 near the neck of the left front body 11 as shown in FIG. The mouthpiece cover 84 includes a bag-like mouthpiece cover main body 85 and a fixing band 86 for fixing the mouthpiece 82. Then, the gripping portion 821 of the mouthpiece 82 can be inserted into the mouthpiece cover main body 85, and the fixing band 86 can be wound around the middle portion 823 of the gripping portion 821 and the mouthpiece main body 822 to be fixed to the neck.

  Due to such a configuration, the oxygen cylinder 7 is inserted into the storage pocket 61 as shown in FIG. 2, and the neck portion thereof is fixed by the fixing band 64. After that, the oxygen cylinder 7 is attached to the jacket main body 1 by covering the oxygen cylinder 7 head with a bag-shaped cylinder head cover 63. At this time, the high-pressure hose 83 extending from the regulator body 81 is extended outward from the open surface 621 of the pocket cover 62 beyond the oxygen cylinder storage unit 6.

  When landing in such a state, as described above, the gas in the cylinder 3 is injected into the air chamber 2 of the life jacket and inflated to ensure buoyancy. However, it may be assumed that the air chamber 2 sinks deeply into the water before it expands. In such a case, the distress removes the fixing band 86 near the neck of the left front body 11 with the right hand and pulls it with the mouthpiece body 822. Then, the mass piece 82 comes out of the mouthpiece cover body 85, and then holds the mouthpiece 82. At the same time, by turning on the on-off valve of the regulator main body 81 of the oxygen cylinder storage section 6, oxygen from the oxygen cylinder 7 is supplied to the victim via the high-pressure hose 83 and the mouthpiece 82. For this reason, oxygen can be secured until buoyancy is obtained and the surface rises to the surface of the water.

  Since the oxygen cylinder and the regulator are attached to the life jacket main body, even if it is submerged in water, the oxygen in the oxygen cylinder can remain in the water for a considerable period of time, and the survival possibility can be remarkably improved. In addition, since the oxygen cylinder and regulator are concentrated on the left side and the left front body, it is possible to easily hold the mouthpiece just by operating the right hand and turn on the regulator. There is an advantage of not. Further, since the positional relationship is as described above, there is an advantage that it does not interfere with operations such as steering.
