SASH ROLLER
To provide a sash roller having a four-wheel constitution for which a cost of manufacture can be reduced by eliminating a need to provide four roller bearings, while maintaining operability for smoothly opening and closing a fitting of a sliding door, a folding door or a movable partition, etc.SOLUTION: An outer ring 6A of a roller bearing 6 each disposed in a center in a longitudinal direction in a front and a rear of a runner body 2, so as to correspond to a roller shaft 5 in the front and the rear, is supported by the runner body 2. The roller shaft 5 operates as a rivet 7, and a cylindrical stepped part 13 coaxial with a rotation axis of a roller 4 is provided on a pair of left and right rollers 4. An inner face A1 in the longitudinal direction of the roller 4 to which the cylindrical stepped part 13 is connected is abutted to a lateral face of an inner ring 6B of the roller bearing 6, the rivet 7 is inserted or fitted in a through-hole 4a in a center part in a radial direction of the pair of left and right rollers 4, and a shaft end is crimped, while a cylindrical surface B1 of the cylindrical stepped part 13 is internally fitted to the inner ring 6B. Thus, the pair of left and right rollers 4 and the inner ring 6B are fixed.SELECTED DRAWING: Figure 2
【課題】４輪構成の吊車において、４個の転がり軸受を備える必要をなくして製造コストを低減しながら、引戸、折戸又は可動間仕切等の建具を円滑に開閉できる操作性を維持する。【解決手段】前後のローラー軸５に対応させてランナー本体２の前後の左右方向中央に１個ずつ配置した転がり軸受６の外輪６Ａをランナー本体２で支持する。ローラー軸５をリベット７とし、左右一対のローラー４に、ローラー４の回転軸と同軸の円筒状段部１３を設ける。円筒状段部１３が繋がるローラー４の左右方向内面Ａ１を転がり軸受６の内輪６Ｂの側面に当接させるとともに、円筒状段部１３の円筒面Ｂ１を内輪６Ｂに内嵌した状態で、リベット７を、左右一対のローラー４の径方向中央部の通し穴４ａに挿通又は嵌入して軸端を加締める。それにより、左右一対のローラー４及び内輪６Ｂを固定する。【選択図】図２
