Abstract: A plain bearing includes: a bearing body; a radial bearing portion arranged on an inner peripheral surface of the bearing body; a thrust bearing portion arranged on an axial end surface of the bearing body; a damper portion arranged on an outer peripheral surface of the bearing body; a dam portion arranged on the outer peripheral surface of the bearing body; and an oil hole having an inlet that opens to at least one of the outer peripheral surface of the bearing body and the dam portion, and an outlet that opens to the inner peripheral surface of the bearing body. The inlet, at least a part of the dam portion, and the damper portion are arranged in this order from an axially inner side toward an axially outer side. An outlet of an upstream side oil passage is connected to the inlet on a radially outer side.

Abstract: Provided are an article advancing device and an article arrangement shelf, wherein the article advancing device has a flexible sheet on which articles can be arranged at a condition where the sheet is extended, a roller to which one end of the sheet is fixed and which winds the sheet in the reverse extension direction, a drive means which rotates the roller in the winding direction of the sheet, and a wall member with which the articles in the first row of the articles arranged on the sheet come into contact. When the articles are arranged on the sheet, the article advancing device stops the winding operation of the sheet by the drive means by the contact of the articles in the first row with the wall member. The article advancing device has a simple article advancing function which employs a horizontally extending shelf basically having no incline and which does not require energy, such as electric power, and can be used regardless of the packaging state of the articles.

Abstract: An article advancing device and an article arrangement shelf with simple structures can be securely operated without electric power. The article advancing device includes elongated drawer members with flexible band-shaped sheets and stopper structures disposed at distal ends of the flexible band-shaped sheets to allow articles to be arranged on the elongated drawer members when pulled-out, rollers for fixing proximal ends of the band-shaped sheets in position and winding up the band-shaped sheets by predetermined driving force while allowing the band-shaped sheets to be freely pulled out, and a main body for housing the rollers and the wound up band-shaped sheets. The rollers are disposed in parallel to each other within the main body, and the elongated drawer members are disposed on the rollers respectively so as not to overlap each other in a width direction.

Abstract: An object is to provide an article advancing device and an article arrangement shelf that can be securely operated with a simple structure while not requiring electric power. An article advancing device of the present invention includes: an elongated drawer member 4 that includes a flexible band-shaped sheet and a stopper structure disposed at a distal end of the flexible band-shaped sheet, and is structured to allow articles Z, . . .
