Neck cover for full face type helmet and full face type helmet

摘要

A neck cover ( 51 ) includes a flexible cover member ( 53 ) and a to-be-attached portion ( 52 ) which serves to attach the flexible cover member ( 53 ) to a head protecting body ( 3 ) of a full-face-type helmet ( 1 ). The flexible cover member ( 53 ) comprises a substantially plate-like flexible cushion member ( 56 ) and a flexible support member ( 57 ) which supports the flexible cushion member ( 56 ). The flexible cover member ( 53 ) is mainly made of a substantially plate-like foamed synthetic resin, a permeability of which measured by using a Frajour type method based on JIS L 1096 falls within a range of 0.1 to 10 cc/cm².sec (preferably 0.2 to 5 cc/cm².sec and more preferably 0.3 to 2 cc/cm².sec). Therefore, a sound which is generated by a traveling wind as it is caught in a ventilator, stabilizer, or the like is effectively prevented from being heard as loud noise to a helmet wearer.
