Abstract: A slider is slightly moved in a direction in which both side surfaces of the slider come in contact with inclined surfaces of impact mitigating parts of neighboring contact strip pieces. For this reason, the inclined surface of the impact mitigating part of the contact strip piece which the slider approaches is relatively downwardly slid with respect to one side surface of the slider. In addition, the inclined surface of the impact mitigating part of the contact strip piece from which the slider moves away is relatively upwardly slid with respect to the other side surface of the slider. As a result, since an impact generated between the contact strip piece and the slider is mitigated by the impact mitigating part without fitting the slider into a stepped section between the neighboring contact strip pieces, the slider is smoothly transferred from the one contact strip piece of the neighboring contact strip pieces to the other contact strip piece.

Abstract: Provided is an acoustic insulation device for a mobile vehicle in which sound transmitted to the exterior of the vehicle body is blocked by being reflected or diffracted by acoustic insulation bodies provided upright to the vehicle body; and the amount of noise that an observer or local residents are subjected to is further reduced. Movement of a mobile vehicle generates noise in, and in the vicinity of, a power collector or a similar device provided upright on the roof (3) of the vehicle. Acoustic insulation bodies (1L), (2L), (1R), (2R) are provided upright on the roof (3), and block noise travelling directly ahead. The noise is diffracted or reflected by the acoustic insulation bodies (1L), (2L), (1R), (2R), and moves so as to be transmitted to the vehicle exterior.

When a plurality of movable guide parts are arranged on a conductive part and a movable guide assembly jig is mounted on the contact plate assembly jig, sliding surfaces of the plurality of movable guide parts are arranged on the same plane in a row by aligning surfaces of movable guide aligning parts. When the contact plate piece and the movable guide part is prevented by the contact plate piece aligning parts, the interval holding part and the movable guide aligning part.

Abstract: An optical disk player comprises a rack which holds an optical pickup unit and moves with rotation of a pinion. The rack includes a fixed rack plate, which is fixed to the optical pickup unit, and a movable rack plate, which can slide in a moving direction of the fixed rack plate, and projecting members on the fixed rack plate are inserted into guide slots in the movable rack plate. A projecting portion which includes a resin spring is provided on the movable rack plate. When the projecting portion presses a supporter on the fixed rack plate, inner surfaces of the guide slots are pressed against the projecting members by a repulsive force of the projecting portion, and a shaky movement between the movable rack plate and the fixed rack plate is avoided, thus a clatter can be reduced when the rack moves with rotation of the pinion.
