The invention provides a vehicle lower structure capable of changing the rotation position of a fender during vehicle driving and braking without using an actuator. A weight member is attached to a region on the inner side in the vehicle width direction in a fender body of an inner fender supported so as to be rotatable about a vertical axis. According to the present invention, when a vehicle travels at a constant vehicle speed or at an accelerated speed, the inside fender is in a first orientation (the orientation of the front surface in the vehicle width direction) by the force of the traveling wind acting on the front surface of the fender body of the inside fender, thereby ensuring high aerodynamic characteristics or steering stability. When the vehicle is decelerated, the inner fender is in a second posture (a posture in which the front surface is inclined rearward toward the outside in the vehicle width direction) by the inertia force of the weight member, and the traveling wind is guided to the brake device of the front wheel, so that the brake device can be effectively cooled.

The utility model provides a freely rotatable hat device, including clothes body and hat, clothes body includes collar part, is connected with the connecting device for the free rotation of hat on the collar part, and the connecting device includes chain seat, first base cloth, second base cloth, third base cloth and chain tooth, the bottom of second base cloth is connected with the top of chain seat, and the upper portion of second base cloth is sewed up with the collar part, the top of third base cloth is connected with the bottom of chain seat, and the lower portion of third base cloth is sewed up with the collar part, and the side of chain seat away from second base cloth is equipped with the open upward chute, is equipped with chain tooth in the chute, and chain tooth is connected with the chute sliding, and the bottom of first base cloth connects chain tooth, and the upper portion of first base cloth is sewed up with the hat, when the head rotates left and right, chain tooth slides in the chute, and then drives the hat to rotate left and right, makes it with the rotation of head and keeps consistent, thereby realizes the rotation of hat freely, can effectively solve the problem that the rotation of traditional hat and clothes is limited after being connected.

This invention discloses a fully press-fit gate valve structure and its manufacturing method. The structure includes a valve body, valve cover, valve stem, gate, and handwheel. The main features include a convex shaft in the middle of the valve stem, a valve stem hole and a mounting hole in the valve cover, and upper and lower inner shoulders manufactured by a hot spinning process within the valve stem hole, along with a positioning groove formed between the upper and lower inner shoulders. The convex shaft is then rotatably mounted within this positioning groove, ensuring that it can rotate freely within the groove without falling off. In other words, the valve stem is positioned and rotated within the valve stem hole. Simultaneously, a press-fit interface is provided at the mounting hole port of the valve cover, containing an O-ring that forms a sealing contact with the outer surface of the valve body. A groove is also provided on the outer circumference of the valve cover to fix the valve body and valve cover, thus forming a sealed installation of the valve cover on top of the valve body. Therefore, the improved gate valve structure combined with the manufacturing method has advantages such as simple assembly, reliable use, reduced processing steps, and lower processing costs.

The problem to be solved by the present invention is to provide a straddle-type vehicle in which an air cleaner box having a sufficient capacity can be disposed on the outer side of a main frame in the vehicle width direction and in which the size in the vehicle width direction can be prevented from increasing. In order to solve the problem, the straddle-type vehicle (1) is provided with: a head tube (F1) which pivots a steering mechanism of a front wheel (WF) so as to be free to rotate; a pair of left and right main frames (F2, F3) connected to the rear part of the head tube (F1); and an air cleaner case (30) that accommodates the air filter (36). The air cleaner case (30) is disposed on the outside of the main frames (F2, F3) in the vehicle width direction. At least a portion of the air cleaner case (30) overlaps the head tube (F1) in a vehicle body side view. The air cleaner box (30) is arranged on the outer side of one side of the main frames (F2, F3) in the vehicle width direction, and functional parts (21, 22) are arranged on the outer side of the other side of the main frames (F2, F3) in the vehicle width direction.

The utility model belongs to file management device technical field, concretely is file management with file placing device, including support column, accomodation mechanism accomodation mechanism sets up at the surface of support column, accomodation mechanism includes three accomodation frame, three accomodation frame are fixedly connected with support column, and three accomodation frame size is different, lighting mechanism, lighting mechanism sets up at the upper end of support column, rotating mechanism, rotating mechanism sets up at accomodation frame's lower surface, and rotating mechanism includes base plate, four ball bearings and four make way for groove, base plate is rotatably connected with accomodation frame, four ball bearings roll in the inner wall of accomodation frame, four make way for groove to set up at the surface of base plate. The utility model is convenient for looking for file, and can be rotated at random on desktop, prevents due to the error and leads to accomodation box rotation.
