To provide a sterilizer preventing ultraviolet ray absorption in a body of a case body and emitting ultraviolet rays to a portion to be sterilized without involving positioning with high accuracy. A sterilizerhas a case bodycontaining a member having an ultraviolet-ray transmission property and a flow passage formed thereinside and an ultraviolet-ray irradiation portionirradiating a predetermined portion of a member configuring the case bodywith ultraviolet rays, in which ultraviolet rays emitted from the ultraviolet-ray irradiation portiontravel in a body of the case bodyto be radiated at least from an end surface on an output end side of the case body

Sterilizer, supply device, and sterilization method

The motion guide device includes a lubricant supply passage provided in at least one of a pair of cover members provided to a movable member and configured to supply lubricant to an endless circulation passage, in which the lubricant supply passage includes at least a first lubricant supply passage &#x3b1; formed to extend in a direction orthogonal to a longitudinal direction of the track member from at least one of a left side surface and a right side surface of the cover member, and a second lubricant supply passage &#x3b2; connected to the first lubricant supply passage &#x3b1;, and a passage shape in a place connected to the first lubricant supply passage &#x3b1; of the second lubricant supply passage &#x3b2; is configured as a diameter-expanded hollow section having a diameter more expanded than a passage shape of another place. Thus, a new form of a cover member is provided.

An ultraviolet irradiation device having higher processability and interfacial adhesiveness, and allowing downsizing is provided. The ultraviolet irradiation device includes an enclosure configured to include a hollow portion being formed inside and being capable of introducing an irradiation object, an outer periphery of the enclosure being covered by a covering portion, and a light source configured to be arranged in an area not covered by the covering portion of the enclosure and project light toward the hollow portion.
