The first end portion includes a first projected portion that protrudes outwardly in a block-width direction from the middle portion so as to form a steplike side, and the second end portion includes a second projected portion that protrudes outwardly in an opposite block-width direction to the first projected portion from the middle portion so as to form a steplike side. |
