摘要： PURPOSE:To obtain a lightweight cylindrical vibration-isolating bush in which life reduction due to electric erosion is not caused. CONSTITUTION:A vibration-isolating rubber body 1 in the center of which an inner cylinder 3 is penetratedly embedded is joined in the inside of an iron outer cylinder 2, and the outer cylinder 2 is pressedly fitted in the inside of the cylindrical retaining part 41 of a lightweight aluminum holder 4. A ring- shaped elastic cover plate 5 is joined both on the open end surface of the retaining part 41 and on the open end surface of the outer cylinder 2 so as to cover the boundary thereof. The intrusion of water or the like into the boundary between the retaining part 41 and the outer cylinder 2 can be prevented by the elastic cover plate 5, so that electric erosion in the pressedly-fitted contact part is not caused.

摘要： PURPOSE:To permit the valve function to be developed sufficiently for both of the positive and the negative pressure in a vessel by permitting both of negative and position pressure valves to be operated by means of a spring. CONSTITUTION:When a positive pressure is formed in a vessel, the pressure acts onto a movable seal plate 7, then a spring 2 is compressed to raise the plate 7. Accordingly, the gas in the vessel is discharged outside. When a negative pressurs is formed in the vessel, the outside air pressure is applied onto a valve member 6 and the movable seal plate 7, and the spring 2 is compressed to lower the valve member 6 together with a spring retain plate 3. Thus, a negative pressure valve 61b is opened to introduce the outside air into the vessel.

摘要： PURPOSE:To reduce the number of parts so sharply as well as to abate the trouble of setting work by making up each of upper and lower tanks of resin material, while installing a setting part to a car panel, in a tip of the bracket, and forming a leg part to be elastically deformed by dint of spring force, in space between the base of each bracket and the setting part. CONSTITUTION:Both upper and lower tanks 1 and 2 are formed of resin material, the upper tank 1 is provided with a base part 42 of a bracket 4 st its top face, and a platelike leg part 43 extending more than the base part 42 is set up in consideration of the plate thickness so as to be deformabe in elastic curvedness. A tip of the leg part 43 is continued to an intermediate position of a platelike setting part 41. Likewise in the lower tank 2, a base part 52 of a bracket 5 is continued to the bottom part, and a platelike leg part 53 extending from the base part 52 is extended up to the lower tank 2. A tip of this leg part 53 is formed into a box type setting part 51. This leg part 53 is also set up in consideration of its plate thickness so as to display a specified spring force at the time of elastic deformation.

摘要： PURPOSE:To secure a vibration isolating rubber piece with good durability without subjecting the material to a drawing process, and facilitate adjustment of the stopper clearance. CONSTITUTION:A bracket 1 is bent into an approx. U-form opening to one side, and its open edge is further bent outside to constitute flanges 11 to serve for mounting. An inner cylinder penetrates a vibration isolating rubber piece 3 and is embedded in its center, and a retaining plate 31 is joined with each end face, and this is pushed from both end faces and contracted and is inserted in the bracket, and the retaining plates are put in pressure contact with the inner surfaces of the bracket side walls so as to establish fixation. The bracket is furnished at its top wall 13 with a stopper surface 13a confronting the side face 3a of the rubber piece with a certain spacing reserved in between, and a stopper plate 4 is set as covering the opening of the bracket and is provided with a stopper surface 4a which confronts the side face 3b of the rubber piece with a certain spacing held in between. The stopper clearance can be adjusted easily by changing the protruding amount of this stopper plate.

摘要： PURPOSE:To provide a steering wheel which causes less vibration and is superior in the feeling to operate a horn pad. CONSTITUTION:There is provided to a spoke core metal piece 13 of a boss part 1 a pin member 7, which extends upward through a through hole 23 of a supporting plate 21 which supports a horn pad 2. The supporting plate 21 is supported by a coil spring 3, and a cylindrical guide wall 4 is provided to the circumferential edge of the through hole 23, inside of which a sliding ring plate 5 is arranged. A cylindrical rubber elastic wall 6 is provided by connecting both ends of which to a base plate 71 fixed to the tip of the pin member 7 and the sliding ring plate 5. The spring force of the coil spring 3 is small, and when the horn pad 2 is pushed by the force which is a little larger than the spring force, the supporting plate 21 moves downward and horn switches 22, 14 are contact and energization is made. When the horizontal vibration is received by the boss part 1, the rubber elastic body wall 6 is shear-deformed, and a dynamic damper is constituted by means of a shear spring force and the mass of the horn pad 2, resulting in reduction of the received vibration thereby.

摘要： PROBLEM TO BE SOLVED: To provide such a vibration proofing device with an outer cylinder in a sectionally non-circular shape as being capable of preventing the outer cylinder from buckling during drawing and keeping it in an originally desired shape. SOLUTION: An engine mount 11 has an inner cylinder 12 mounted on an engine, an outer cylinder 13 mounted on a body and an elastic insulator 14 provided to connect the inner cylinder 12 and the cylinder 13 together. The outer cylinder 13 is in a sectionally elliptical shape with a plane part 13b formed by joining two metal plates constituting the outer cylinder 13 together in layer and served as a reinforcement 15. When the engine mount 11 is drawn, the outer cylinder 13 is subjected to stress toward its axial, center and reduced in diameter. At this time, on the easy-to-deform plane part 13b of the outer cylinder 13 a reinforcement 15 is provided to prevent buckling due to stress.
