To provide a continuously variable transmission that not only smooths continuously variable transmission, but also has a simple structure and can be provided at low cost, prevents drive of a pedal side shaft from being stopped during shift, has less noise, vibration or transmission loss, and has components hard to wear.SOLUTION: A gear continuously variable transmission without needing a control device is configured such that after a sun gear is mounted on a primary drive shaft for one rotation, and a planetary gear support is rotatably mounted around the sun gear, an outside planetary gear is arranged so that an internal gear is meshed with the outside thereof, and the planetary gear support rotates only in the same direction as that of the sun gear and the internal gear, as a result, when both an input shaft and an output shaft are stopped, each gear is in a low speed state with constant meshing due to a gear ratio, and is in a standby state of being directly connected with the sun gear and the internal gear, and with one-way clutch connection of the planetary gear support, the rotation of the input shaft is always transmitted to the output shaft even under a light load or a high load, so there is no need to relax a pedal when a force is needed.SELECTED DRAWING: Figure 1

    【課題】無段階の変速を円滑に行うのみならず、構造が簡単であって安価に提供することができ、変速時にペダル側軸の駆動を停止させることなく、騒音、振動、伝動ロス等が少なく、構成各部が摩耗し難い無段変速機を提供する。【解決手段】一次駆動軸に太陽歯車を一方回転に取り付け、太陽歯車のまわりに遊星歯車支持体に回転自在に取付けられた内、外側遊星歯車を配しこの外側に内歯車を噛合せて、この遊星歯車支持体を太陽歯車と内歯車の回転方向と、同一の方向にのみ一方回転とすることにより入力軸も出力軸も停止状態のときは、各歯車は歯車比による常時噛合いの低速状態で、尚克太陽歯車と内歯車と直結待機状態であり、遊星歯車支持体のワンウエイクラッチ接続により、軽負荷時も、高負荷時も入力軸の回転はいつも出力軸に伝えられてここ一番、力の必要な時にペダルの力を抜く必要がない制御装置不要の歯車無段変速機。【選択図】図1
