A connecting structure has a first member (10) and a second member (20). The first member has a first base portion (11), a protruding portion (12) that protrudes from an end surface (31) of the first base portion, and a protrusion (15) that extends in a protruding direction of the protruding portion from an end surface of the protruding portion. The second member has a second base portion (21), and a groove portion (22) formed in the second end surface (32) of the second base portion. The protruding portion fits into the groove portion. The first member and the second member are connected together by a side surface (13, 14) of the protruding portion contacting a side surface (23, 24) of the groove portion. A length (D1) from the end surface of the first base portion to a tip end of the protrusion is longer than a length (D2) from the end surface of the second base portion to a bottom of the groove portion. |
