Abstract: A damper apparatus includes a piston having a flange-shaped piston main body and piston rods which project from both ends of the piston main body, a cylinder having a cylinder main body which accommodates the piston main body slidably and cylindrical portions which support slidably the piston rods, respectively, a fastener which is attached to the one cylindrical portion so as to secure the cylinder to an opening/closing member, and a coil spring which biases the one piston rod to project from the other cylindrical portion such that a distal end portion of the piston rod abuts a circumferential edge of an opening portion of a vehicle.

Abstract: There is provided a piping installation structure for a vehicle which is installed under a floor of a vehicle body and configured to support and fix a long part including at least piping, the piping installation structure including: a clamp member for supporting and fixing the long part; a stud for fixing the clamp member under the floor of the vehicle body; a stud fixing member to which the stud is fixed; and an underfloor structural member installed under the floor of the vehicle body, in which the stud fixing member and the underfloor structural member are joined to form a closed cross section on a plane which is orthogonal to a front-rear direction of the vehicle body.
