PROBLEM TO BE SOLVED: To provide a mask which does not generate positional shift easily at the time of receiving strong wind pressure or mounting a helmet and never covers ears by providing a belt for mounting the mask with an ear part detouring circuit of a nonlinear type capable of detouring the ear part of a mounting person at the time of mounting. SOLUTION: A composite mask 1 suitably used at the time of riding a motor bike, etc., consists of a filter mask 2, belts 42a and 42b for mounting the mask and a mask cover 3 connecting these belts and being in contact on the gas flow-in side of the filter mask 2, and the cover 3 is provided with a mask mounting tool. The mask mounting tool is provided with a mounting belt part of a nonliner type 40 and consists of an internal belt-like part overlapped with the cover 3 and the two external belt-like parts 42a and 42b respectively extending in a direction opposite to the cover 3 from both tip parts of the cover 3. In addition, a bending part to be in contact with the ear part of a mounting person at the time of mounting is provided to allow the bending part to operate as an ear part detouring part 44. |
