A cylindrical waterproof rubber plug to be inserted into a hole formed in a housing is provided. The center of the waterproof rubber plug, has a through-hole into which a wire of outer diameter A is inserted. The plug consists of a main body part and a crimping part of inner diameter B formed integral with the main body part. The dimensions A and B are related by the equation (A-B)/B=0.1 DIFFERENCE 0.8. Thus, even when the wire engaged in the plug is obliquely bent, sufficient sealability can be ensured.
