Abstract: ホイールリムのウエル部を構成する裏側ウエル壁部の、バルブ孔と対向する部位に、前記ウエル部を構成するウエル底部に沿って裏方へ凹むウエル凹部が形成された構成とした自動車用ホイールであるから、走行中に空気圧検出装置付エアバルブの遠心力によって生ずる振れを、前記ウエル凹部の形状効果により抑制することができ、自動車の操安性や乗り心地などを向上することができる。また、ホイールリムのウエル部を構成する表側ウエル壁部の、バルブ孔が形成される部位に、空気圧検出装置付エアバルブの空気圧検出装置の表側部分が嵌入されるように、前記ウエル部を構成するウエル底部に沿って表方へ凹むウエル凹部が形成されている自動車用ホイールとした場合にも、前記と同様の作用効果を奏し得る。

Abstract: PROBLEM TO BE SOLVED: To provide a valve device which is capable of properly demonstrating a function for controlling inflow/outflow of a fluid by suppressing reduction in sliding property of a main valve due to a dimension change caused by the fluid to be used.SOLUTION: In a valve device 1, an operating valve 13 performs conversion between a state where a fluid can flow into and flow out of a third flow passage 8 and a state where the fluid can not flow into and flow out of it, consequently, the balance of power acting on the main valve 3 is changed, the main valve 3 is slid within a cylinder 2 so as to be abutted on a valve seat member 9 or separated from the valve seat member 9, and the inflow/outflow of the fluid is controlled between a first flow passage 6 and a second flow passage 7. Since the sliding surface 16a of the main valve 3 is formed of a metal material, a dimension change due to swelling or shrinkage caused by exposure to a fluid to be used can be suppressed. Further, since a portion of the main valve 3 to be abutted on the valve seat member 9 is formed of a resin material or a rubber material, the sealing property of the portion to be abutted on the valve seat member 9 can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a float excellent in durability with respect to the inner pressure of a fuel tank.SOLUTION: Disclosed is a float 21 configured by welding a cup body 22 and a lid body 23, therein a cup side rib 34 installed in the cub body 22 and an annular lid side rib 47 installed in the lid body 23 are formed so as to be separate from each other in such a state that any external force does not act on the lid body 23, and so as to be brought into contact with each other in accordance with the elastic change of the lid body 23 in such a state that the external force acts. Thus, it is possible to suppress the deflection quantity of the lid body 23 which is generated when the external force acts on the lid body 23, and to reduce any stress which acts on the lid body 23 or any stress which acts on a weld. Therefore, it is possible to improve the strength of the lid body 23 or the weld. Also, since the cup body 22 and the lid body 23 are not brought into contact with each other in welding, it is possible to position the cup body 22 and the lid body 23 with high accuracy, to improve weld quality, and to improve the strength of the weld.

Abstract: PROBLEM TO BE SOLVED: To provide an automobile wheel that exerts an effect of reducing cavity resonant noise generated in a tire-internal space while an automobile travels.SOLUTION: The automobile wheel 1 includes: first bottom parts 13 provided inward in a radial direction of a front side bead seat 12a and a back side bead seat 12b between the front side bead seat 12a and back side bead seat 12b; and second bottom parts 31 provided inward in the radial direction of the first bottom parts 13. The first bottom parts 13 and second bottom parts 31 are alternately provided in a circumferential direction. This configuration increases difference in area between area of a cross section Sb in the radial direction of the tire-internal space P in sections where the first bottom parts 13 are provided and area of a cross section Sa in the radial direction in sections where the second bottom parts 31 are provided and thus allows improvement in the effect of reducing cavity resonant noise.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicular wheel formed with a valve hole into which an air valve can be mounted to avoid the occurrence of air leakage or the like in the front sidewall of a well section provided in the rim section of a one-piece wheel.SOLUTION: The vehicular wheel includes a front sidewall 13a in a well section 13 of a rim section 2 that is formed with a fixing hole 20a to which an air valve 101 is fixed, a front sidewall-opposing section 53 in a disk section 3 opposite to the front sidewall 13a that is formed with an insertion hole 20b through which the air valve 101 is inserted and a valve hole 20 consisting of the fixing hole 20a and the insertion hole 20b. This construction allows the air valve 101 to be fixed to only the rim section 2 which is formed with the fixing hole 20a. As a result, even if vibration deformation repeatedly takes place while a vehicle runs, the fixation of the air valve 101 can stably be ensured.
