PROBLEM TO BE SOLVED: To provide an elevator in which maintenance workability can be improved, a water receiver capable of covering the whole below a conveyor can be installed and down-sizing of a driving source can be achieved.SOLUTION: An elevator 8 related to the present invention comprises: an extension part 30 which is included between plural conveyor rollers 11 and extends in a rotation axis direction of the conveyor rollers 11 a bridging part 31 which extends from both sides of the edges of the extension part 30 upward, extends more outside than a pair of rails 10, 10 and bridges over the pair of the rails 10, 10 a driving source 20 which is below a water receiver 13 and is arranged at one side of the rotation axis direction a rotation shaft 21 which extends in the rotation axis direction below the water receiver and is rotated by drive of the driving source and crank structures 23, 23 which connect both sides of the edges of the rotation shaft 21 with the bridging part 31, 31 and move the extension part 30 up and down by rotation of the rotation shaft 21. A sterilization tray T contacting to the upper part of the extension part 30 is moved up and down.COPYRIGHT: (C)2015,JPO&INPIT【課題】メンテナンスの作業性を向上させ、かつ、コンベア下の全部を覆うことができる水受けを設置でき、そして、駆動源の小型化を図ることができる昇降機を提供することを課題とする。【解決手段】本願発明に係る昇降機8は、複数の搬送ローラ11間に介在し、搬送ローラ11の回転軸方向に延びる延在部30と、延在部30の端部両側から上方に延びるとともに、さらに一対のレール10、10よりも外側に延びて、一対のレール10、10の上方を跨ぐ跨ぎ部31と、水受け部13の下方であって、回転軸方向の一方側に配置された駆動源20と、水受け部の下方で回転軸方向に延び、駆動源の駆動により回転する回転シャフト21と、回転シャフト21の端部両側と跨ぎ部31、31とを連結し、回転シャフト21の回転により延在部30を上下させるクランク機構23、23と、を備え、延在部30の上部に当接する滅菌トレイTが上昇又は下降することを特徴とする。【選択図】図3
