A mudguard device adapted to conceal a cable which is disposed therein, said mudguard device being characterized by : a mudguard having a cover plate that extends along a curved line (L), and two opposite fixing plates , each of which is parallel to the curved line (L), extends from a bottom surface of said cover plate toward the other one of the fixing plates , has a bent end portion distal from said cover plate , and cooperates with said cover plate to define a first receiving space ; and a cable holding member having two engaging portions that respectively and removably engage said first receiving spaces , a connecting portion that is connected between said engaging portions , that cooperates with said cover plate to define a second receiving space that is larger than said first receiving spaces , that is formed with a plurality of openings spaced apart from each other in a longitudinal direction parallel to the curved line (L), that is flexible in both the longitudinal direction and a transverse direction perpendicular to the longitudinal direction, and that has a flexibility in the longitudinal direction larger than that in the transverse direction, said second receiving space and said first receiving space being adapted for receiving the cable , and characterized in that a plurality of abutting portions are disposed on a side of said connecting portion facing said second receiving space , and have a flexibility in the transverse direction larger than that of said connecting portion in the transverse direction. a mudguard having a cover plate that extends along a curved line (L), and two opposite fixing plates , each of which is parallel to the curved line (L), extends from a bottom surface of said cover plate toward the other one of the fixing plates , has a bent end portion distal from said cover plate , and cooperates with said cover plate to define a first receiving space ; and a cover plate that extends along a curved line (L), and two opposite fixing plates , each of which is parallel to the curved line (L), extends from a bottom surface of said cover plate toward the other one of the fixing plates , has a bent end portion distal from said cover plate , and cooperates with said cover plate to define a first receiving space ; and a cable holding member having two engaging portions that respectively and removably engage said first receiving spaces , a connecting portion that is connected between said engaging portions , that cooperates with said cover plate to define a second receiving space that is larger than said first receiving spaces , that is formed with a plurality of openings spaced apart from each other in a longitudinal direction parallel to the curved line (L), that is flexible in both the longitudinal direction and a transverse direction perpendicular to the longitudinal direction, and that has a flexibility in the longitudinal direction larger than that in the transverse direction, said second receiving space and said first receiving space being adapted for receiving the cable , and two engaging portions that respectively and removably engage said first receiving spaces , a connecting portion that is connected between said engaging portions , that cooperates with said cover plate to define a second receiving space that is larger than said first receiving spaces , that is formed with a plurality of openings spaced apart from each other in a longitudinal direction parallel to the curved line (L), that is flexible in both the longitudinal direction and a transverse direction perpendicular to the longitudinal direction, and that has a flexibility in the longitudinal direction larger than that in the transverse direction, said second receiving space and said first receiving space being adapted for receiving the cable , and <EOS>
