A display device for a vehicle includes a first frame, a second frame configured to be move along a first direction with respect to the first frame, a roller rotatably coupled to the second frame and configured to move along the first direction based on movement of the second frame, and a flexible display that is at least partially wound around the roller and that is configured to be bent around the roller. The flexible display has an end portion fixed to the first frame. A front surface of the flexible display defines an externally exposed area that is configured to increase based on an increase of a distance between the first frame and the roller.

To provide a sprocket that reduces the influence of tension fluctuations concurrent with load torque variations to suppress noise and vibration, and that prevents an increase in tension fluctuations, noise, and vibration even when the chain tension is low and the load torque is small, and in regions where engagement between the chain and sprocket is free of the influence of tension. The sprocket has a plurality of seating points for the chain when the chain sits under no load set between adjacent pairs of the teeth such that their radial positions change in a circumferentially continuous manner. The radial positions of the seating points under no load have a variation pattern in which the radial positions increase and decrease depending on circumferential positions of the seating points.

The present invention relates to a carrier installed on the roof of a vehicle such as a car or SUV and to a lifting multi-joint roof carrier for a vehicle, which is used to easily load or unload an object on or from a vehicle roof. The present invention relates to a lifting multi-joint roof carrier for a vehicle, which is vertically movable up, rotatable, etc. in a process of loading or unloading cargo, to allow an object to be smoothly loaded or unloaded and have a structure with an aesthetically pleasing appearance.

A roof coating sprayer including a cart assembly and a sprayer assembly. The cart assembly has a frame with a plurality of wheels. The frame has a sprayer support assembly with a lateral member, and vertical spray nozzle attachment members arranged along the lateral member. The attachment members each mount a spray nozzle and can be vertically and horizontally shifted relative to the lateral member. The roof coating sprayer can be pulled over the surface of a roof at a uniform rate, enabling a coating of a uniform thickness to be sprayed on the roof. Additionally, the cart assembly can be self-propelled, enabling a uniform rate of speed for the cart and thereby enabling uniform application of coating.

A rear drive transmission system for a motorcycle includes a driving wheel, a center wheel, and a driven wheel. The center wheel includes a transmission wheel A and a transmission wheel B that are coaxially arranged. The transmission wheel A is fixedly connected to an opposite surface of the transmission wheel B. The driving wheel is drivingly connected to the transmission wheel B. The transmission wheel A is drivingly connected to the driven wheel, and the driving wheel is detachably and fixedly connected to an output shaft of a motor or engine. The driven wheel is detachably connected with a rear wheel shaft of the motorcycle. The center wheel is rotatably connected with a rear fork rotation center shaft through a bearing. The motorcycle is with the motorcycle rear drive transmission system.

A display device for a vehicle includes a first frame, a second frame configured to move along a first direction with respect to the first frame, a first roller spaced apart from the first frame, a second roller rotatably coupled to the second frame and configured to move along the first direction based on movement of the second frame with respect to the first frame, and a flexible display that is at least partially wound around the second roller, that is configured to be bent around the second roller, and that has an end portion fixed to the first frame. A front surface of the flexible display defines an externally exposed area that is configured to increase based on an increase of a distance between the first roller and the second roller.
