<p>To provide a coupling structure for a roof portion and side portions of a vehicle, in which the coupling structure can improve rigidity of entire grooves without increasing the number of parts. In a coupling structure for a roof portion and side portions of a vehicle, a roof portion 1 is constructed at an intermediate position on an underside of a roof panel 3 in a front-back direction of a vehicle body by disposing a strip-like roof center member 4 along a car width direction; a side body portion 2 is constructed by installing a roof side rail 6 in an upper end portion on an interior side of each side body outer panel 5 along the front-back direction of the vehicle body; grooves 8 are formed in the front-back direction of the vehicle body by joining together opposite side portions of the roof portion 1 and upper end portions of the side body portions 2; and a bead 41 of a fixed length is formed on both left and right ends of the roof center member 4, extending in the car width direction from end edges, and an edge portion 42 located at each side of the bead 41 is joined to an upper edge portion 61a of the roof side inner rail 6.
