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.

Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In addition, for convenience of description, the arrow UP suitably shown in each figure is a vehicle upward direction, an arrow FR is a vehicle front direction, and an arrow LH is a vehicle left direction. Therefore, when the directions of up and down, front and rear, and left and right are described in the following description, the up and down directions of the vehicle vertical direction, the front and rear directions of the vehicle front and rear direction, and the left and right directions of the vehicle (vehicle width direction) are indicated.

[0025] like figure 1 , figure 2 As shown, a pair of left and right metal roof rails 20 extending in the front-rear direction are provided at both ends in the vehicle width direction of the roof 12 of the vehicle of the present embodiment. The roof rail 20 includes a lower reinforcement 22 having a substantially top-hat sh...

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...
