An adaptor is secured to a first object. The adaptor includes an anchoring part and an adjustment part. The anchoring part includes a distally facing anchoring surface and a proximally facing first control surface. The adjustment part has a distally facing second control surface positioned to abut against the first control surface. The first control surface or the second control surface or both is/are helical. Thereby a relative z position of the adjustment part with respect to the anchoring part is defined by the relative orientation of the adjustment part with respect to the common axis while the second control surface abuts against the first control surface. This is used to adjust the z position of the adjustment part relative to the first object, in connection with the orientation of the adjustment part being defined and possibly fixed by the function of the adaptor/the adjustment part

Mud flap assemblies including a frame, a securing assembly and mud flap panels; the securing assembly enabling the frame to be secured to a hitch assembly having a shaft, for further attachment to a hitch receiver secured to a vehicle; the frame having two side portions secured to a center portion to which the securing assembly is attached. The center portion of the frame is preferably configured to rest on a portion of a bumper of the vehicle to minimize vibration of the frame during use. The frame includes two side portions having channels within which reside at least a portion of fasteners that attach mud flap panels to each of the respective side portions. Methods of installing mud flap assemblies and attaching the flap panels are also disclosed.

A vehicle includes a vehicle body having an underbody, the vehicle body defining an inner fender, the inner fender forming an opening in the underbody of the vehicle body. A wheel assembly has a rim and a tire, and the wheel assembly is positioned within the inner fender. A suspension knuckle is disposed within the inner fender to permit motion of the wheel assembly relative to the vehicle body. A brake shield is mounted on the suspension knuckle and an inner fender undercover panel is secured on one of the brake shield and the suspension knuckle and disposed inboard of the wheel assembly. The inner fender undercover panel is configured to move up and down with vertical movement of the suspension knuckle and to move with turning movement of the wheel assembly.

A fender suspension arrangement for suspending a fender of a vehicle, the fender suspension arrangement comprising a bracket, connectable to a frame of the vehicle, an elongated tube attached to the bracket, a pair of fender brackets connectable to the fender of the vehicle, wherein the fender brackets are attached to the elongated tube at a distance from each other, and an elongated washer element, arranged in abutment with the elongated tube, the elongated washer element extending between, and being connected to, the bracket and at least one of the fender brackets.

A mounting structure for a vehicular resin component provided with a panel body having a design surface on a surface of the panel body; a reinforcement rib arranged upright on a back surface of the panel body; and a mounting member for a vehicle. The reinforcement rib includes a proximal end portion connected to the panel body and formed with a thickness thinner than a thickness of a distal end portion. The distal end portion of the reinforcement rib includes an inclined surface formed between the distal end portion and the proximal end portion with increasing thickness toward the leading end side, and is provided with a locking hole with a hole direction inclined in the direction of inclination of the inclined surface. In the mounting member, a locking claw capable of being fitted in the locking hole is formed.

An optically and aerodynamically improved body for a motor vehicle has a wheel well cover with at least one wheel well for receiving a wheel. The wheel well cover is designed in such a way as to be adjustable by an adjusting mechanism in accordance with the wheel angle, and includes at least two ring portions which surround part of the wheel and which are arranged in such a way as to be movable at least partially into each other and at least partially relative to one another.

An improved removable and installable fender for the bolsters of a trailer group relies on the use of a bracket on the bolster, the bracket having two retaining arms. A single fastening means is provided on the bolster to receive a bolt securing a medial portion of the end of the fender to the bolster, allowing the distal sides of the fender to be retained between the two retaining arms of the bracket and the body of the bolster.
