    摘要: In a safety gear for an elevator, a pressing spring device applies a resistance force against movement of a normal-wedge guide member in a direction of moving away from a guide rail. A normal-wedge member has a reverse-wedge guide surface becoming more distant from the guide rail as extending upward. A reverse-wedge member is movable with respect to the normal-wedge member along the reverse-wedge guide surface. A vertical-direction spring device applies a resistance force against upward movement of the reverse-wedge member with respect to the normal-wedge member. A spring constant of the vertical-direction spring device is lower than a spring constant of the pressing spring device. The vertical-direction spring device has a region in which a rate of change in force generated along with increase in upward displacement amount of the reverse-wedge member with respect to the normal-wedge member decreases as compared to that in initial displacement.

    摘要: A headlight module includes: a light source that emits light; a projection lens that receives and emits the light; a holder including a flexible portion having a length in a direction of an optical axis of the lens and having a fixed end and a movable end, the holder holding the lens movably relative to the light source by holding the lens with the movable end; and a driver that moves the lens. The lens is translated on a plane perpendicular to the axis due to deflection of the flexible portion. The holder includes first and second flexible portions including plate-like portions parallel to the axis and perpendicular to each other. One end of the first flexible portion is the fixed end. Another end of the first flexible portion is connected to one end of the second flexible portion. Another end of the second flexible portion is the movable end.
