Problems solved by technology

However, in the roof body of such a structure, thermal strain caused by the difference in thermal expansion coefficient between the outer layer and the inner layer may occur, and there is room for improvement in a structure that suppresses the occurrence of this thermal strain.

Abstract

A resin roof is provided with: a roof body including a resin outer layer constituting a roof panel of a vehicle and a resin inner layer provided in a predetermined region other than a peripheral edge portion of the outer layer; a first joining part provided on the peripheral edge part of the outer layer and joined by a first adhesive to a first joined part provided on a first base material on the vehicle body side; and a second joining part provided in the inner layer and joined by a second adhesive to a second joined part provided on a second base material on the vehicle body side, one of the first adhesive and the second adhesive corresponding to one of the outer layer and the inner layer having a higher coefficient of thermal expansion is configured so as to have higher followability than the other of the first adhesive and the second adhesive.

Description

technical field [0001] The present invention relates to a resin vehicle roof. Background technique [0002] A roof interior for a vehicle in which a foamed molded body is integrally molded on the outside of the vehicle interior of a panel-shaped base material disposed so as to face the vehicle interior at the interior side of the vehicle's roof panel is known. (for example, refer to Japanese Patent Laid-Open No. 2011-225150). The shape of the outer side of the vehicle interior of the foam-molded body is set to be approximately equal to the shape of the inner side of the vehicle roof panel, and the foam-molded body is attached to the vehicle in a state in which the outer side of the vehicle body is press-contacted to the interior side of the roof panel. top panel. [0003] As described above, an inner layer made of a resin such as a foamed molded body is provided between the roof panel of the vehicle and the base material disposed on the inside of the vehicle interior rathe...
