To provide a sash roller having a structure capable of increasing a load resistant strength as well as reducing a cost of manufacture.SOLUTION: In the sash roller, a movable frame 4 which supports a wheel 3 inside left and right side plates 2, 2 of a fixed frame 1 is supported so as to swing according to an advance/retreat of an adjustment screw 5 supported on the fixed frame 1. The left and right side plates 6, 6 of the movable frame 4 comprise: arc-shaped abutting edges e provided in a bilaterally symmetric manner in a front upper edge part; abutting pieces c protruding in an arc shape above an upper edge of a back plate 7 of the movable frame 4, provided in the bilaterally symmetric manner in the rear upper edge part; and a latch part 6c serving as a fulcrum of swinging of the movable frame 4, provided so as to protrude outward from a bilaterally symmetric position. The left and right side plates 2, 2 of the fixed frame 1 comprise: an elevation guide 2a for restricting an upper limit of the abutting edges e, and a movement guide 2b for restricting the upper limit of the abutting pieces c, provided along each upper edge in a bilaterally symmetric and integrated manner; and support holes 2c for permitting and limiting a movement of the latch part 6c, provided respectively in a bilaterally symmetric manner.SELECTED DRAWING: Figure 1
【課題】 耐荷重強度を高め且つ製造コストをも削減し得る構造を持った戸車の提供。【解決手段】 固定枠１の左右側板２，２の内側に車輪３を支持した可動枠４を、前記固定枠１に支持された調整ネジ５の進退に応じて揺動可能に支持した戸車であって、前記可動枠４の左右側板６，６は、その前上端部に円弧状の当接縁ｅを左右対称に備え、前記後上端部に可動枠４の背板７の上縁より上位へ円弧状に突出する当接片ｃを左右対称に備え、当該可動枠４の揺動の支点となる掛止部６ｃを左右対称の位置から外側方へ向けて突出して備え、前記固定枠１の左右側板２，２は、それぞれの上縁に沿って、前記当接縁ｅの上限を規制する昇降ガイド２ａ及び前記当接片ｃの上限を規制する移動ガイド２ｂを左右対称に且つ一体的に備えると共に、前記掛止部６ｃの移動を許容し且つ制限する支え孔２ｃを左右対称にそれぞれ備えることを特徴とする戸車。【選択図】 図１
