PROBLEM TO BE SOLVED: To reinforce the joint part of a counter without imposing a load. SOLUTION: Metallic and hollow crosspieces (4), (5) are arranged on the rear surface of respective counters (1), (2) at the side of the joint part (3). The crosspiece includes bolt insertion holes to which a bolt (6) is inserted. One of the bolt insertion holes is a tapped hole. When the bolt is screwed into the tapped hole and disposed through the crosspieces, the crosspieces are fixedly separated at prescribed interval (d) by screwing between the disposed bolt and the tapped hole. Then a tight contact state is kept in the joint part of the two counters. COPYRIGHT: (C)2005,JPO&NCIPI
