  In a mud guard that is divided into a mud guard upper and a mud guard lower as in Patent Document 1, the distance between the mounting portion on the vehicle body side (the mud guard upper attached portion) to which the mud guard upper is fixed and the tire (mud guard lower) is There may be differences depending on vehicle specifications. In this case, if the mudguard upper is formed in a shape that matches the specification (low specification) with a short distance (upper setting distance) between the mudguard lower and the mudguard upper mounting part, the mudguard is used for the specification with a long upper setting distance (high specification). The upper and the mudguard lower are separated from each other to generate an opening (non-covering portion), and the function as a mudguard is deteriorated. On the other hand, if the mud guard upper is formed in a shape that matches the high specification, the lower part of the mud guard upper interferes with the mud guard lower and the mud guard upper cannot be attached in the low specification.

  Such inconvenience can be solved by using different types of mud guard uppers (two types in the case of low specification and high specification) corresponding to the difference in the upper setting distance. However, a plurality of types of mudguard uppers having different shapes depending on the upper set distance must be prepared, which is complicated.

  Therefore, an object of the present disclosure is to provide a mudguard structure that can flexibly cope with a change in the position of the mudguard upper attached portion without deteriorating the function as a mudguard.

  In order to achieve the above object, the mudguard structure for a vehicle according to the first aspect of the present invention is divided into an upper mudguard upper and a lower mudguard lower, and a mudguard that covers the tire from above and a mudguard.
