At this time, as shown in FIG. 5D, the presence of the mask dropout suppressing protrusion 140 causes the lower end edge portion Mbd of the mask main body Mb to be pressed against the mask lower end edge locking piece 130.

<5. Effect of this example>
According to the mask spacer 100 of this embodiment, the mask main body Mb can be attached by inserting the upper end edge portion Mbu of the mask main body Mb from the mask wearer U side and flipping it back to the front side by providing it in the upper portion of the annular spacer main body 110. By providing a pair of left and right mask upper end edge locking pieces 120 that are locked to the left and right mask upper end edge locking pieces 120, the upper end edge portion Mbu of the mask body Mb is locked to the left and right pair of mask upper end edge locking pieces 120, respectively, when the mask M is worn. As a result, the mask body Mb is integrated with the mask spacer 100, so that the mask wearer U makes a loud voice when wearing the mask M and raises and lowers the mouth while preventing the suffocation due to the pressure of the mask M. Even if it is moved greatly, the gap between the face and the mask M is less likely to occur, and the function of the mask M such as preventing the inflow of dust and pollen can be fully exhibited.
Further, the mask M is worn by providing the nose accommodating portion 111 formed on the mask wearer U side of the annular spacer main body 110 in the upper portion of the annular spacer main body 110 to position the nose Un of the mask wearer U. Even in a situation where the mask wearer U sometimes opens wide or the mask body Mb is subjected to some external force to cause a relative deviation between the face and the mask M, the mask wearer U protrudes from the face. Since the nose Un is reliably positioned at the nose accommodating portion 111 of the annular spacer main body 110, the adhesion between the mask spacer 100 and the face can be improved.
Therefore, it is possible to prevent the suffocation due to the pressure of the mask M while surely wearing the mask M on the face.
In particular, when the mask M is worn at a construction site or a manufacturing site where a safety helmet is worn, the above-mentioned effect is remarkable.

By providing the piece 130, when the mask M is worn, the upper end edge portion Mbu of the mask body Mb is locked to the pair of left and right mask upper end edge locking pieces 120, and the lower end edge portion Mbd of the mask body Mb is the lower end of the mask. The mask Mb is locked to the edge locking piece 130, and as a result, the mask main body Mb is securely held at two upper portions and one lower portion of the annular spacer main body 110, so that the mask M is like a construction site. Even in a situation where the mask wearer U opens wide when wearing the mask, or when some external force is applied to the mask body Mb to cause a relative deviation between the face and the mask M, a deviation between the face and the mask M occurs. It can be made difficult.

Further, since the mask dropout suppressing protrusions 140 for suppressing the mask main body Mb from falling off from the mask lower end edge locking piece 130 are provided on both sides of the mask lower end edge locking piece 130, the lower end edge portion of the mask main body Mb Since Mbd is pressed against the lower end edge locking piece 130 of the mask and is difficult to fall off from the lower end edge locking piece 130 of the mask spacer 100, the mask M is mounted only on the upper end edge Mbu of the mask body Mb. The mask M can be held more reliably even when the mask M is provided.
