To provide a lock device for a seat back table that can be simply structured.SOLUTION: A lock device for a seat back table (hereinafter, a lock device) 1 is a lock device that is disposed in a seat back 11 and configured to lock a seat back table 12 in a retracted position and that includes: a rotary operation member 2; a first lock member 3 connected with the operation member 2 via a connection mechanism slidable between a first pin 2C and a first elongated hole 3B so as to rotate along with the rotation of the operation member 2; and a second lock member 4 connected with the first lock member 3 via a connection mechanism slidable between a second pin 3B and a second elongated hole 4B so as to be pushed and rotated in the opposite direction to the first lock member 3 in accordance with the rotation of the operation member 2. The operation member 2 is rotated in one direction from a predetermined position, and thus the first lock member 3 and the second lock member 4 engage with each other such that the seat back table 12 is held in the retracted position.SELECTED DRAWING: Figure 6

    【課題】構造の簡素化を図ることが可能なシートバックテーブル用ロック装置を提供すること。【解決手段】シートバックテーブル用ロック装置(以下、ロック装置)1は、シートバック11に設けられて、シートバックテーブル12を格納位置にロックする装置であり、回転式の操作部材2と、操作部材2の回転に連動するよう操作部材2に対して第1のピン2Cと第1の長孔3Dとのスライド可能な連結構造を介して連結される第1のロック部材3と、操作部材2の回転により第1のロック部材3とは逆方向に押し回されるように第1のロック部材3に対して第2のピン3Bと第2の長孔4Bとのスライド可能な連結構造を介して連結される第2のロック部材4と、を有する。操作部材2を所定位置から一方向に回転させることにより、第1のロック部材3と第2のロック部材4とがシートバックテーブル12に対して格納位置に保持するように係合する。【選択図】図6
