ABSTRACT:
A recess is provided in the inner surface of a primary shield plate which is connected to a cap body of a helmet through a pivotal mounting means, and a step depressed from the inner surface of the primary shield plate is formed at the entire peripheral edge of an opening of the recess. An inner shield plate is fitted to the step and bonded thereto with a soft adhesive, so that a heat insulating space tightly closed in the recess is defined by the primary shield plate and the inner shield plate. The inner surfaces of the primary shield plate and the inner shield plate are formed into a continuous surface which comes into close contact with a sealing member provided at a peripheral edge of a window opening in the cap body. This ensures that clouding of the inner surface of the shield can be prevented regardless of conditions of use such as the presence and absence of travel wind and the temperature of the open air.
