Abstract: A method for manufacturing a door catch including a main body made of a thermoplastic resin, and a magnet board for attracting a piece to-be-attracted of a door, wherein supports and a leg portion which constitute the main body are integrally molded of the resinous material under the state under which the spacing between the upper parts of the supports is expanded so as to permit the magnet board to be inserted therebetween, and wherein the magnet board is fixed between the supports owing to the shrinkage of the resinous material at the time of cooling thereof.

Abstract: A caster equipped with a stopper for use in a wagon, a chair or the like, comprising a proper whose shell is formed into a substantially circular arc and which supports wheels through an axle, a stopper piece which is provided at an inner end of the proper and which freely contacts with parts of the wheels so as to lock or unlock the wheels, a lock pin which protrudes from a window provided in the proper, a compression spring which is interposed between the stopper piece and boss portions of the proper and whose elasticity acts on the lock pin as an unlocking force, a control piece which is provided with a lock hole for snugly and slidably inserting the lock pin therein, which is mounted at a desired inclination angle relative to the lock pin and whose base end is fixed to the proper, and a release pin which protrudes from a window provided in the proper and which, when pushed inwards, depresses a free end of the control piece.

Abstract: A castor for an article of furniture which comprises a connecting member connected to the article and having a cylindrical portion at the lower side thereof, a wheel having a pair of shafts projecting from both sides thereof, a main body having a generally tubular portion fitted rotatably to the cylindrical portion of the connecting member and an arc-shaped wheel-accommodating-and-bearing portion connected to the tubular portion and having arc-shaped side walls which receive the shafts of the wheel and having at the lower sides thereof resilient portions for preventing slip-off of the wheel.
