Elastic cloth and protector

An elastic cloth comprising an array of unit sheet bodies which are connected to one another and which are aligned in a first direction and a second direction that intersects the first direction, each of said unit sheet bodies including:

• a main sheet body part having a first sheet surface and a first boundary which loops around said first sheet surface, said first boundary including a first lateral side, and a second lateral side, said first lateral side having two opposite ends respectively connected to two opposite ends of said second lateral side at two junctions to form a loop that loops around the first sheet surface;
• and
• a connecting part connected to said main sheet body part and having a first connecting surface which adjoins said first boundary and faces in the same direction as said first sheet surface;
• said first lateral side including two first lateral side segments which are respectively parallel to the second direction and the first directions, and a first corner segment which is connected between said first lateral side segments;
• said first corner segment forming a center of said first lateral side, said center of said first lateral side being disposed between said two opposite ends of said first lateral side which connect said second lateral side at said two junctions;
• said second lateral side including two second lateral side segments which are respectively parallel to the first direction and the second direction, and a second corner segment which is connected between said second lateral side segments;
• said second corner segment forming a center of said second lateral side, said center of said second lateral side being disposed between said two opposite ends of said second lateral side which connect said first lateral side at said two junctions (ja);
• said connecting parts of adjacent ones of said unit sheet bodies adjoining each other, said first connecting surface of said connecting part of each of said unit sheet bodies being sloped to indent from said first sheet surface such that a first groove is formed around said main sheet body part of each of said unit sheet bodies;
• for each of said unit sheet bodies, an average slope of said first connecting surface adjacent to said center of said first lateral side being greater than an average slope of said first connecting surface adjacent to said center of said second lateral side.
