In a lever device for a hydraulic operation where hydraulic pressure is generated in a master cylinder by rotation of a lever, to make invariable an operation of a pushrod, which operates a piston of the master cylinder by being pushed at one end thereof by an adjuster of the lever, irrespectively of an adjustment of the adjuster. The lever is supported by a rotational shaft to be rotatable around the rotational shaft relative to the master cylinder, while a knocker member separate from the lever is supported to be coaxially rotatable. A knocker portion of the knocker member receives an end of the pushrod, which operates the piston. A positional relationship between the pushrod and the knocker portion is made invariable irrespectively of a change in a distance between the adjuster and the knocker portion by an adjustment of the adjuster.

A headrest holder includes two tension pieces defined in the body portion thereof and a head portion. The two tension pieces, each including a protrudent portion, are spaced apart from each other along the longitudinal direction of that body portion, while being in a mutually facing relation, so that a headrest stay inserted in the headrest holder is retained between the two protrudent portions against wobbling. Further, those two tension pieces and either the head portion or a support bracket of seat frame establish three supportive points. Namely, the headrest holder inserted in the support bracket is retained against wobbling because the two protrudent portions and the headrest holder's neck portion closely contact the support bracket. Also, a headrest stay inserted in the headrest holder is retained against wobbling because the two protrudent portions and headrest holder's head portion closely contact the headrest stay.

A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11. A support rod 8 is inserted in the shaft member 11, and the shaft member 11 is elastically supported to the support rod 8 through an elastic body 10. The elastic body 10 is provided within a quarter of the periphery of the support rod 8 that is located, when viewed along the axis of the shaft member 11, forward of the line of action of a radial shaft load on the shaft member 11 with respect to the direction of rotation of the pulley body 5. With this configuration, when the drive belt 3 deviates to one side, the pulley body 5 is immediately angularly moved so that it is inclined with a level difference with respect to the direction of the radial shaft load and is positioned obliquely relative to the drive belt 3. In this manner, a force of compensating for the deviation of the drive belt 3 is produced to avoid its wobbling.

The invention discloses an anti-swing device of a crane. The device comprises a supporting foot stand, a fixed bottom plate, a balance bottom plate, a fixed supporting arm, a telescopic arm and a siderotating foot rod. Butt joint clamping seats are fixedly mounted on the outer surfaces of the two sides of the fixed bottom plate. The supporting foot stand is fixedly mounted at the front part of the fixed bottom plate. The side rotating foot rod is movably installed on one side of the supporting foot stand. The outer surface of the side rotating foot rod is movably sleeved by a side rotating clamping rod. Inclined supporting feet are movably installed at the bottom of the side rotating foot rod. Spherical clamping grooves are formed in the middles of the inner sides of the inclined supporting feet. A ball clamping pin is fixedly installed on the outer surface of the lower end of the side rotating foot rod. The upper portion, fixedly close to the ball clamping pin, of the outer surface of the side rotating foot rod is movably sleeved by a fixing clamping sleeve. According to the crane anti-swing device, the crane anti-swing device is provided with an inclination angle adjusting structure, so that the stability of the crane anti-swing device is improved; meanwhile, the crane anti-swing device is provided with an inclination auxiliary fixing structure, so that the fixing operationis firmer, and the anti-swing effect of the crane anti-swing device is improved.
