<p>PROBLEM TO BE SOLVED: To improve assembly ability by a method wherein a main piercing stand is mounted on a support member placed in a cooking chamber, and a number of auxiliary piercing stands can be pierced in a coupling member attached to the support member or pulled off therefrom. SOLUTION: A support member 210a is provided with a cut annular drum body 213, and support legs 212a and 212b extending from the two ends of the drum body 213. The support leg 212b is extended to the center of the support member 210a and a main piercing stand 220 is vertically upward extended from the end part of the support leg 212b. A coupling member 240a is removably mounted so that a number of auxiliary piercing stands 230 can be pierced in and pulled out from the support member 210a. A through-hole 241 is vertically formed in the central part of the coupling member 240a so that the main piercing stand 220 is pierced through, and a number of insertion holes are radially formed around the through-hole 241 serving as a center. The sizes of the through-hole 241 and the insertion hole are properly set to a value enough to allow insertion and pull-off of the main piercing stand 220 and the auxiliary piercing stand 230.</p> |
