To provide a two-stage type platform fence which can extend an inspection cycle more than before.SOLUTION: A platform fence 2 (2R) includes: 1) a first rack and pinion mechanism part 21 which includes a first pinion 21p pivotally supported by a door pocket part 10 and a first rack 21r disposed on a rear end side door 11, in order to slidingly move the rear end side door 11 relative to the door pocket part 10; 2) a second rack and pinion mechanism part 22 including a second pinion 22p pivotally supported by the door pocket part 10 and a second rack 22r disposed on a tip side door 12; a 3) a motor 30 for driving the first pinion 21p; and 4) a transmission gear 23 engaged with the first pinion 21p and the second pinion 22p. The transmission gear 23 transmits rotation of the first pinion 21p accompanying the sliding movement of the rear end side door 11 to the second pinion 22p, so that the second pinion 22p rotates and the tip side door 12 is interlocked.SELECTED DRAWING: Figure 2

    【課題】点検周期を従来より長くできる2段式のホーム柵を提供すること。【解決手段】ホーム柵2(2R)は、1)戸袋部10に枢支された第1ピニオン21pと後端側扉11に設けられた第1ラック21rとを有し、戸袋部10に対して後端側扉11をスライド移動させるための第1ラック・アンド・ピニオン機構部21と、2)戸袋部10に枢支された第2ピニオン22pと先端側扉12に設けられた第2ラック22rとを有する第2ラック・アンド・ピニオン機構部22と、3)第1ピニオン21pを駆動するモータ30と、4)第1ピニオン21pと第2ピニオン22pとに噛合された伝動ギア23と、を備える。伝動ギア23が、後端側扉11のスライド移動に伴う第1ピニオン21pの回転を第2ピニオン22pへ伝えることで、第2ピニオン22pが回転し、先端側扉12が連動する。【選択図】図2
