A protective cover including a bellows portion wherein a plurality of valleys and peaks are arranged alternately. The valleys include a plurality of large valleys and a plurality of intermediate valleys whose inside and outside diameter dimensions at bottoms are greater than those of the large valleys, and the large valleys and the intermediate valleys are arranged alternately. Small valleys whose inside and outside diameter dimensions at bottoms are greater than those of the intermediate valleys are respectively arranged between the large valleys and the intermediate valleys. The peaks are respectively arranged between the large valleys and the small valleys as well as between the intermediate valleys and the small valleys, and apexes of the peaks have a same outside diameter dimension as one another. The apexes of the peaks are made thinner than the bottoms of the large valleys.
