[0002]

2. Description of the Related Art In a conventional pitcher's headgear, a protective shell made of a hard synthetic resin is formed integrally in a substantially C-shape in plan view so as to cover from both sides of the head to the back of the head along the shape of the human head. A pair of left and right foamed polystyrene cushioning materials divided into two parts at the left and right center positions of the occiput are adhered to the inner surface of the occipital region in such a manner that a vertically extending groove is formed between their adjacent ends, and each of the cushioning materials is Has an ear mounting through-hole larger than a through-hole formed at a position corresponding to the ear hole of the protective shell, and furthermore, at the upper portion of both front ends of the protective shell, a mounting portion for a belt of adjustable length is provided. (For example, see Japanese Patent No. 3001872).

[0003]

In a conventional pitcher headgear, a protective shell starts from a thin portion at the center of the right and left occipital region corresponding to the groove due to the presence of a groove formed between adjacent ends of both cushioning members. Since the body can be elastically deformed to the reduced diameter side or the increased diameter side, it can be worn in a state where it is fitted to each of a plurality of users with different head sizes. Since the operating force on the reduced diameter side or the increased diameter side applied to both front end portions is concentrated at one position at the center of the back of the protective shell, cracks are likely to occur in the protective shell due to repeated stress concentration.

Furthermore, after the pitcher's headgear is mounted on the head, when the belt mounted over the mounting portions on the upper front ends of the protective shell is tightened, the rear half of the left and right cushioning material is placed on the back of the human body. Because the elastic deformation starting from the right and left center position of the back of the protective shell is limited,
The protective shell is elastically deformed toward the reduced diameter side substantially starting from a portion corresponding to the relatively large ear mounting through hole formed in each cushioning material. Stress concentration occurs at the periphery of the hole, and cracks are likely to occur at the periphery of the ear mounting through hole of each cushioning material due to repetition of the stress concentration.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and a main problem thereof is that a protective shell is configured to be elastically deformable on a reduced diameter side or an increased diameter side so that the size of a head can be increased.
