PROBLEM TO BE SOLVED: To provide a bicycle suspension capable of reducing manufacturing cost as a simpler structure with strong strength and excellent stability.SOLUTION: A bicycle suspension includes: a suspension unit 100 having an upper cylindrical member 101 and a lock unit 200 having a lower cylindrical member 201. The upper and lower cylindrical members 101 and 201 are vertically movably fitted to each other. The suspension unit 100 includes: a bearing fixed to an upper section in the upper cylindrical member 101; a slide shaft 103 having an outer periphery which has a polygonal cross section and is slidably inserted into the bearing and a cylindrical inner periphery; a support base 105 for supporting the outer periphery at a lower end of the slide shaft 103 via a step; a suspension bolt 104 inserted into the slide shaft 103; and a coil spring 106 inserted into the outer periphery of the slide shaft 103. An inner periphery of the bearing is formed into a polygonal shape corresponding to the outer periphery of the slide shaft 103 and vertically moves without rotation of the upper cylindrical member.

    【課題】強度が強く安定性に優れるとともに、より簡潔な構造として製造コストを低減できる自転車用サスペンションを提供する。【解決手段】上円筒部材101を有するサスペンションユニット100と、下円筒部材201を有するロックユニット200を備え、上下円筒部材は上下動自在に互いに嵌合している。サスペンションユニットは、上円筒部材内上部に固定された軸受けと、軸受けに摺動自在に挿通された断面多角形状の外周と円筒状の内周を有するスライド軸103と、スライド軸の下端部外周を段差を介して支持する支持ベース105と、スライド軸内に挿通されたサスペンションボルト104と、スライド軸外周に挿嵌されたコイルスプリング106とからなる。軸受けの内周は、スライド軸外周に対応した多角形状に形成され、上円筒部材が回転することなく上下動する。【選択図】図1
