When assembling the face protection plate assembly 10, the packing 13 is attached to the back surface of the support plate 11 and the fixture 25 is attached to the support plate 11. Next, the face protection plate 1 is arranged on the front surface of the support plate 11, and the female engagement member 12a of the engagement member 12 is inserted into the mounting hole 1a from the front side of the face protection plate 1 to form the male engagement member. 12b is pushed from the rear surface side of the support plate 11 into the female engagement member 12a. Then, after all the engaging members 12 are attached to the face protection plate 1, the sheet 14 is attached to the back surface of the packing 13.

When the face protection plate assembly 10 is assembled to the cap body 2, the outer mounting hole 23 of the support plate 11 is engaged with the fixing tool 5a of the hammock 4, and the inner mounting hole 24 of the ear string 8 is attached. Engage the fixture 5b and engage the rest of the hammock 4 with the fixture 25 of the face protection plate assembly 10. As a result, the central portion 11a of the support plate 11 has an inclination angle that allows the face protection plate 1 to be moved up and down in front of the wearer's eyeglasses.

When the helmet with a face protection plate is used, the wearer wears the face protection plate 1 on the head while pushing it up. Then, when the face protection plate 1 is pulled down as shown in FIG. 7, the face protection plate 1 maintains the most forwardly inclined angle as shown at the position P1 in FIG. At this time, the left and right engaging members 12 of the face protection plate assembly 10 engage with the wide portions 22b of the left and right guide holes 22, respectively. The position of the face protection plate 1 in this case passes through the front of the eyeglasses even when the wearer wears the eyeglasses.

As shown in, the central engaging member 12 engages with the wide portion 21c of the central guide hole 21, and holds the position P3 of the face protection plate 1. At this time, part of the support plate 11 is deformed, so that the engaging member 12 can engage with the wide portion 21c.

In this embodiment, since the face protection plate 1 can be pulled down to the position P1 having a large pulling down angle, the face protection plate 1 does not hit the eyeglasses. Then, since the face protection plate 1 can be drawn right before the eyeglasses shown at the position P2 and immediately before the naked eye shown at the position P3, the gap between the eyeglasses or the naked eye and the face protection plate 1 can be kept to a minimum. It is possible to prevent flying objects, dust, etc. from getting into the wearer's eyes and improve work safety.

Further, since the face protection plate 1 is only supported by the support plate 11 fixed to the cap body 2 so as to be able to move up and down, the structure is simplified. Further, since the face protection plate 1 is moved up and down inside the cap body 2, the face protection plate 1 does not collide with or get caught in an obstacle. Since the packing 13 for shock absorption is attached to the back surface of the support plate 11, it is possible to doubly absorb the shock applied to the front head of the wearer.

In the above embodiment, the support plate 11
Although the three guide holes 21 and 22 are provided in the above, it goes without saying that four or more guide holes can be provided. In this case, the guide hole may be made longer toward the center. Further, although one wide portion 21b is provided in the middle of the extension portion of the central guide hole 21, if a plurality of wide portions are provided, the pulling down angle of the face protection plate 1 can be set in multiple stages. The face protection plate 1 is transparent, but it may be a colored body.

[0034]

As described above, the helmet with a face protection plate according to the present invention can be drawn to the wearer's face side after pulling down the face protection plate, so that the wearer wearing glasses can see the naked eye. It is also suitable for wearers. Since the face protection plate is supported by the supporting member, the structure is simplified. Further, since the face protection plate is moved up and down inside the cap body, the face protection plate is less likely to collide with or be caught by an obstacle, and safety is improved.
