A vehicle weight measurement device includes a moving body, an attachment body, a stopper ring provided between the moving body and the attachment body, and a rotation prevention part configured to prevent the moving body and the attachment body from rotating relative to each other. The stopper ring includes a fixing part fixed to one of the moving body and the attachment body and a separation and detachment prevention part provided at the other of the moving body and the attachment body and configured to prevent the moving body and the attachment body from separating and detaching, without inhibiting movement of the moving body. The rotation prevention part includes a pin fitted from the moving body to the attachment body.

A vibration damper may include an external tube and at least one internal tube. The external and internal tubes may be disposed in a coaxial manner relative to one another. An annular gap may exist between the external tube and the internal tube, and the annular gap may be fluidically connected to the internal tube. The annular gap may form a balance chamber for receiving damper oil and damper gas for preloading of the damper oil in the balance chamber. The vibration damper may further include a separating element disposed in the balance chamber. The separating element may be axially displaceable and may separate the damper oil from the damper gas in a fluid-tight manner.

Embodiments of the present invention describe a recreational vehicle spindle, including a spindle body having one or more sockets in the spindle body, and an upper attachment mechanism in contact with the spindle body and adapted to attach to a steering component. The spindle also includes a lower attachment mechanism in contact with the spindle body and adapted to attach to a ski or wheel. The one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.

The present invention provides a steering system for an in-wheel motor vehicle capable of controlling driving torques and speeds of in-wheel motors mounted in left and right wheels to be different from each other at the time of curve driving of the vehicle to generate a steering angle of the wheel for the curve driving, and performing a steering angle control of sensing the generated steering angle and fixing the steering angle to a desired steering angle.

Provided are: a slide bearing configured so that degradation in sliding performance caused by the entry of dust, muddy water, etc. can be prevented at low cost; and a strut-type suspension using the slide bearing. A slide bearing (1) is provided with: an upper case (2); a lower case (3) joined to the upper case (2) in a pivotal manner and forming an annular space (5) between the upper case (2) and the lower case (3); and an annular center plate (4) disposed in the annular space (5). An annular lip (43) is formed integrally at the outer peripheral edge (423) of the flange (42) of the center plate (4). The lip (43) is in contact, while deflecting, with an annular protrusion (252) formed in an annular groove (24) in the upper case (2) and covers a thrust bearing surface (422) and a thrust supporting surface (251).

A strut assembly including a reservoir tube that extends about and along a center axis and has an interior surface and defines a chamber. A bearing sleeve is disposed in the chamber of the reservoir tube and extends about and along the center axis between a proximal end and a distal end. The bearing sleeve presents an inner surface and an outer surface. A damper body tube is disposed in the bearing sleeve and is moveable relative to the bearing sleeve. A piston assembly is disposed in the damper body tube. The outer surface of the bearing sleeve has a tubular portion and a protrusion portion that extends radially outwardly relative to the tubular portion and annularly and providing an interference fit between the outer surface of the bearing sleeve and the interior surface of the reservoir tube.
