PROBLEM TO BE SOLVED: To solve the problem that: a conventional jetform helmet fully covers a relevant user's flank for the purpose of the user's safety; however, if such a helmet is left worn, a cellphone cannot be used, and the helmet has to be taken off, leading to delaying response to the cellphone. SOLUTION: A jetform helmet whose flank is furnished with a space 1 enabling a cellphone to be used, is provided. Thus, as a cellphone can be used even if the helmet is left worn, the helmet is in no need of being taken off intentionally, thus enabling quick response to the cellphone.
