To provide a saddle lifting device that can accurately lock the height of a saddle to a predetermined position and firmly and stably endure the weight of a rider.SOLUTION: A saddle lifting device 10 includes: a lifting rod 2 slidably inserted into a fixation cylinder 1; stroke springs 5b, 5c biasing the lifting rod 2 toward the upper side in a cylinder axis direction; a lock mechanism A configured to lock the lifting rod 2 to a predetermined height; and lock switching means B configured to switch the lock mechanism A between a lifting allowable state and a locked state of the lifting rod 2. The lock mechanism A includes: a lock member 20 having a plurality of lock recessed portions 20a along the cylinder axis direction; and a pawl member 22 having pawl locks 22a engageable with the lock recessed portions 20a. The lock switching means B includes a pawl switching member 24 configured such that in a state where pulling from an operating portion 30 operated by a rider is input, the pawl switching member is pulled by wire 32 to disengage the pawl locks 22a from the lock recessed portions 20a and pushes the pawl locks 22a in a direction to bring the pawl locks into engagement with the lock recessed portions 20a.SELECTED DRAWING: Figure 1
【課題】サドルの高さを所定の位置で的確にロックでき、乗員の体重にも耐え得る強固で安定したサドル昇降装置を実現する。【解決手段】固定筒1にスライド自在に挿入される昇降ロッド2と、昇降ロッド2を筒軸方向上方へ付勢するストロークバネ5b,5cと、昇降ロッド2を所定高さでロックするロック機構Aと、ロック機構Aを昇降ロッド2の昇降許容状態とロック状態とに切り替えるロック切替手段Bとを備え、ロック機構Aは、筒軸方向に沿って複数の係止凹部20aを有する係止部材20と、係止凹部20aに噛み合うツメ掛け22aを有するツメ部材22とを備え、ロック切替手段Bは、乗員が操作する操作部30からの引っ張りが入力された状態でワイヤ32に引かれてツメ掛け22aを係止凹部20aから離脱させ、ツメ掛け22aを係止凹部20aに噛み合う方向へ押圧するツメ切替部材24とを備えるサドル昇降装置10とした。【選択図】図1
