THE INVENTION RELATES TO A CUSHIONING BODY HAVING AN L-LETTER SHAPED CROSS SECTION, IN WHICH THE THICKNESS AT THE END OF THE L-LETTER IS THICKER THAN THAT AT THE CORNER PORTION. SPECIFIC CONSTITUTIONS FOR MEETING THE THICKNESS REQUIREMENT INCLUDE THE FOLLOWINGS: (1) FIXING MEMBER- GUIDING GROOVES ARE FORMED SUCH THAT THE DEPTH THEREOF BECOMES DEEPER FROM THE ENDS OF THE L-LETTER TOWARD THE CORNER PORTION, THEREBY MAKING THE THICKNESS OF THE CUSHIONING BODY BASED ON THE BOTTOM PORTION OF THE FIXING MEMEBER-GUIDING GROOVE GRADUALLY REDUCING FROM THE ENDS OF L-LETTER TOWARD THE CONNER PORTION; (2) WITHOUT FORMING THE FIXING MEMBER-GUIDING GROOVES, THE CUSHIONING BODY IS MOLDED SO THAT THE THICKNESS OF ITSELF IS GRADUALLY REDUCED FROM THE ENDS OF L-LETTER TO THE CORNER PORTION; AND (3) PROTRUSIONS ARE FORMED OUTSIDE AT BOTH ENDS OF THE L-LETTER OF THE CUSHIONING BODY. WHEN BOUND WITH A FIXING MEMBER, THE CUSHIONING BODY PREVENTS THE BINDING FORCE OF THE FIXING MEMBER FROM CONCERTRATING ON THE CORNER PORTION.FIGURE 1
