Patent attributes
A chin guard support mechanism includes first and second fixed-side members, and a moving-side member fixed to the chin guard. When the chin guard pivots forward from a down position in a rising direction, an annular following surface provided on the moving-side member pivots forward while following an annular followed surface provided on the second fixed-side member to make the chin guard rise while moving forward. It is possible to provide a helmet that allows the chin guard support mechanism capable of relatively excellently raising/lowering the chin guard to have a simple structure, allows to operate the chin guard support mechanism smoothly, obviates the necessity of making the structure in a region including an end of the chin guard including the chin guard support mechanism and a vicinity thereof bulky, and obviates the necessity of making the widthwise size of the helmet large.
