Abstract: One object is to provide a magnetic fluid sealing device in which a magnetic fluid retained between a polar plate and a drive portion can be effectively prevented from spilling, so as to retain waterproofness for a long period. A magnetic fluid sealing device of the present invention includes a ring-shaped polar plate encircling a drive portion and retaining a magnet and a magnetic fluid retained in a gap between the drive portion and the polar plate by a magnetic force of the magnet. The polar plate has a spill preventing portion provided thereon, the spill preventing portion having a projecting wall that is disposed distant from an end surface of the polar plate retaining the magnetic fluid, so as to prevent spill of the magnetic fluid.

Abstract: One object is to provide a drone capable of achieving desired performance by preventing entry of foreign matter such as water droplets or dust particularly into a power portion thereof. A drone of the present invention is provided with a fixed section having a motor housing for housing a motor therein and a rotary section having a propeller shaft supported via a bearing so as to be rotatable with respect to the motor housing and configured to rotate integrally with the propeller. In an opposed portion where fixed-side components constituting the fixed section and rotary-side components constituting the rotary section are opposed to each other, there is provided a foreign matter entry prevention unit configured to prevent foreign matter from entering an inside of the motor housing.

Abstract: A line-winding device including a tension detection unit that can be incorporated in a reel, can be downsized, and can measure a tension with high accuracy even at the time of stopping without the need to bend a line path. A line-winding device is configured to include: a spool capable of winding a fishing line; an operating part for winding the fishing line around the spool; a support shaft portion for rotatably supporting the spool; a restoring force generation unit for generating a restoring force between the support shaft portion and the spool; a restricting part for restricting a rotational movement amount of the spool; and a detection unit for detecting the rotational movement amount of the spool.
