A door device for a vehicle includes: a cable (35) for connecting a handle device (31), which is mounted to the door panel (23) of the door body (21) covering a door opening (14) of the vehicle body (11) in an openable and closable manner, and a lock unit (32), with which the door body (21) is engaged. A cable holding member (58) mounted to the handle device (31) is displaced between an engagement position (A1) at which the cable holding member (58) engages with the cable (35) and a non-engagement position (A2) at which the cable holding member (58) does not engage with the cable (35). An interference section (44) is provided to the door panel (23). The interference section (44) is configured in such a manner that, in a state in which the handle device (31) is mounted to the door panel (23), the interference section (44) interferes with the cable holding member (58) located at the non-engagement position (A2) and does not interfere with the cable holding member (58) located at the engagement position (A1).
