Disclosed while keeping cost without adopting a complex configuration, the rod gripping manually to provide a lifting apparatus for X-ray imaging apparatus for moving parts to allow the lifting of the image receiving part. The apparatus includes a spring member 2 mounted freely winding and unwinding to the shaft member, and a slider 5 which is connected to the distal end of the spring member, a support member connected to the slider, the position of the slider in a desired position and fixed and comprising a locking mechanism for locking mechanism is pivotally mounted on the slider, the locking latch 18 having a locking claw portion 19, the locking grooves 15, the locking claw portion is engaged and comprising a large number rack 14 which is pieces formed, the latch for locking, is urged in the direction in which the locking claw portion is engaged with the locking groove, locking against the locking groove by rotating in a counter biasing direction claw portions locking is released in the direction in the state where the locking claw portion is engaged with the engagement groove, the slider is moved in a direction in which the spring member is wound is allowed, the spring member is paid out move to is blocked. .BACKGROUND【課題】複雑な構成を採用せずにコストを抑えながら、手動によって握り棒、受像部等の可動部品を昇降可能としたX線撮影装置用の昇降装置を提供する。【解決手段】軸部材に巻き取り及び繰り出し自在に取り付けられたバネ部材2と、バネ部材の先端に連結されたスライダー5と、スライダーに連結された支持部材と、スライダーの位置を所望位置で固定する係止機構を具備し、係止機構は、スライダーに回動自在に取り付けられた、係止爪部19を有する係止用ラッチ18と、係止爪部が係止する係止溝15が多数個形成されたラック14を具備し、係止用ラッチは、係止爪部が係止溝に係止する方向に付勢され、反付勢方向に回動することで係止溝に対する係止爪部の係止が解除され、係止爪部が係止溝に係止している状態では、スライダーは、バネ部材が巻き取られる方向への移動は許容され、バネ部材が繰り出される方向への移動は阻止される。【選択図】図3
