PROBLEM TO BE SOLVED: To provide a spacer wherein the width of a connection part thereof can be made smaller to reduce the width of a spacer body so that materials can be saved, and the construction of a molding device can be simplified to easily manufacture the spacer, thereby reducing the cost of products. SOLUTION: A projection 2a is formed on each of the upper and lower sides of a planar spacer body 2. Connection parts 3, 4, which are to be connected respectively to the opposite ends of another spacer body 2, are provided respectively on the opposite ends of the spacer body 2. In one of the connection part 3, an engaging recess 3c and an engaging projection 3d are formed orthogonally to the upper surface of the body 2, while in the other connection part 4, an engaging recess 4c and an engaging projection 4d are formed orthogonally to the upper surface of the body 2. |
