According to the inner cap 5 according to the above, the impact force applied to the inner cap 5 can be sufficiently absorbed.

  That is, when an oblique impact force is applied to the inner cap 5 (a downward impact force that is inclined obliquely with respect to the vertical direction of the inner cap 5), each beam extends in the horizontal direction with the conventional inner cap. Therefore, the inner cap is displaced in the horizontal direction with respect to the wearer's head, and the impact force cannot be sufficiently absorbed. On the other hand, in the inner cap 5 according to this embodiment, since the beams 9 and 11 extend obliquely, the inner cap 5 remains against the head of the wearer P even when an oblique impact force is applied. There is almost no deviation and the impact force can be absorbed sufficiently.

  In addition, when a downward impact force (for example, a vertical impact force) is applied to the inner cap 5, the conventional inner cap exerts the impact force mainly by bending (elastic deformation) of the beam extending in the horizontal direction. In the inner cap 5 according to this embodiment, the impact force is absorbed by both the bending (elastic deformation) of the front beam 9 and the bending (elastic deformation) of the rear beam 11. Are dispersed in the front-rear direction and the like, and the impact force can be sufficiently absorbed.

  Furthermore, according to the inner cap 5, the left and right front beams 9 </ b> A and 9 </ b> B and the left and right rear beams 11 </ b> A and 11 </ b> B are provided, and the wearer P wears the inner cap 5. The intermediate portions 19 and 21 of the beams 9 and 11 are in contact with the head of the wearer P (the head of the wearer P is contacted at four points). Since it pinches | interposes from a direction and the left-right direction, the wearer P can wear the inner cap 5 in the more stable state.

  Further, according to the inner cap 5, the front beam 9 is provided on the center side in the left-right direction of the inner cap 5, and the rear beam 11 is provided on the outer side of the front beam 9. The inner cap 5 can be covered without a sense of incongruity. That is, the width of the person's head is generally wider on the rear side than on the front side, so depending on the form of the person's head, each beam 9, 11 (each beam 9, 11 and worn) A contact portion with the head of the person P) is provided, and when the wearer P wears the inner cap 5, the feeling of strangeness is eliminated.

  Moreover, according to the inner cap 5, since each beam 9 and 11 is circular, the impact force can be absorbed more reliably. That is, if each beam 9 and 11 is circular arc shape, when the inner cap 5 receives impact force, not only each beam 9 and 11 will bend, but each beam 9 and 11 11 is twisted (elastically deformed) around the axis in the extending direction, so that a larger impact force can be absorbed.

  Moreover, according to this inner cap 5, since the attachment part (projection part 35A-35F, neck part 37, 37A, 37B) for attaching to the inner side of a cap body (hood part 3) was provided, the cap body (hood part) 3) It can be attached so that it does not come off easily.

  Incidentally, as described above, two front beams 9 are provided, two rear beams 11 are provided, and intermediate portions 19 and 21 of the four beams 9 and 11 are provided on the head of the wearer P. The inner cap 5 is in contact with the head of the wearer P at least at four places. Here, the description of at least four places is that when the wearer P wears the inner cap 5, the portion other than the beams 9 and 11 (for example, the portion of the edge 17 of the bowl-shaped main body portion 7) is the wearer P. This is because it abuts against the head.

  In addition, when the wearer P wears the inner cap 5, if the inner cap 5 is installed in the head of the wearer P in a stable state, the number of the beams 9, 11 may be appropriately changed.

  For example, in the left-right direction of the inner cap 5, one front beam may be provided at the center, one rear beam may be provided on the left side, and one rear beam may be provided on the right side. A configuration in which five or more beams are appropriately provided may be used.

  Moreover, although the attachment part was provided in three places, the attachment part may be one place, two places, or three places or more.

  In the above description, the inner cap 5 is installed in the hood portion 3, but the inner cap 5 is disposed inside a cap-shaped cap (for example, a cap such as a baseball cap) 41 as shown in FIG. 11. You may install in a hat of other forms.

  The inner cap 5 described above has a main body portion 7 and a plurality of beams 9 and 11 provided on the main body portion 7 on the inner side (concave side) of the main body portion 7 and is worn by the wearer P. Sometimes, each of the beams 9 and 11 comes into contact with different parts of the head of the wearer P from different directions and is placed and supported on the head of the wearer P, and the main body portion 7 is an example of the inner cap configured to cover the head of the wearer P.

  That is, each of the beams in the inner cap is provided integrally with the main body at a position different from each other, and one end of each beam is positioned on the top side of the main body, Each other end of the beam is located on the edge side of the main body. When a person wears an inner cap, each beam extends in an oblique direction with respect to the horizontal direction and the vertical direction.

  Further, when the inner cap is viewed from the side in a predetermined direction (for example, when viewed from the right to the left), at least a pair of the beams has a “C” shape, a “F” shape, or The lower two line segments have a long “X” shape. Each beam sandwiches the wearer's head from the front-rear direction and the left-right direction.

  When viewed from the front, instead of or in addition to the fact that the lower two line segments of at least a pair of beams have a long “X” shape or the like when viewed from the side in a predetermined direction, (E.g., when viewed from front to back), at least one pair of beams is “X” -shaped, “X” -shaped, or “X” having two long lower line segments. It may be in the shape of a letter. And each beam may pinch | interpose a wearer's head from the front-back direction or the left-right direction.

  Furthermore, as already understood when focusing on the pressing force of each beam pressing the wearer's head when the wearer wears the inner cap (the pressing force when the wearer wears the inner cap) The horizontal component of the pressing force at the contact portion of the beam located on the front side of the inner cap (the contact portion located on the front upper side of the head) is directed from the front to the rear. The horizontal component of the pressing force at the abutting portion of the beam located on the rear side (the abutting portion located on the rear upper side of the head) is directed from the rear to the front, and the inner cap The horizontal component force of the pressing force at the abutting portion of the beam located on the right side (the abutting portion located on the upper right side of the head) is from right to left and is on the left side of the inner cap. The abutment part of the beam (positioned in the upper left of the head) Horizontal component force of the pressing force in the in the contact portion that) and is from left to right. Further, the vertical component force of the pressing force at the contact portion of each beam is from the top to the bottom.
