Abstract: In a power seat operation device, a slider that is supported so as to be slidable in a radial direction with respect to a dial slides toward the radial direction center of the dial during rotation of the dial. A knob engagement portion that is provided to the slider is thereby disposed between a pair of slider engagement portions that are provided to a knob. This enables rotational operation of the knob to be restricted. However, during rotational operation of the knob, one out of the pair of slider engagement portions opposes the knob engagement portion from toward the radial direction center of the dial. This enables rotational operation of the dial in conjunction with sliding of the slider to be restricted.

Abstract: An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.

Abstract: A flexure chain blank sheet includes frame units. Each frame unit includes a frame portion, and flexure elements. The flexure element includes a distal end portion, and an extending portion. The frame portion includes a pair of lengthwise frames and a pair of lateral frames. The first lateral frame connects between tail portions of the flexure elements. The second lateral frame is formed of a distal end linking portion which is constituted by connecting between respective adjacent extending portions. The distal end linking portion includes first cut-off portions to be cut along a longitudinal direction between the adjacent extending portions, and second cut-off portions to be cut along a width direction between the distal end portion and the extending portion.

Abstract: An electronic device manufacturing apparatus includes a conveyer, a plurality of heaters, gas supply source, narrow path part, and a plurality of guide parts. The conveyer conveys a work to which an uncured conductive adhesive agent is applied. The narrow path part includes a narrow path formed along a locus in which the conductive adhesive agent passes. The guide parts which guide the inert gas to feed into the narrow path include gas dispersion members which store the heat of the heaters and disperse the inert gas.
