PROBLEM TO BE SOLVED: To provide a gear type transmission which can give a good transmission state, even when used in a state that the positions of an input shaft and the output shaft are changed each other, and does not need a large structural improvement for changing an inclination angle between the input shaft and the output shaft.SOLUTION: In the gear type transmission in which the input shaft 31 capable of being freely rotated around the first shaft center X1 is synchronously connected to the output shaft 81 capable of being rotated around the second shaft center X2 obliquely crossing the first shaft center X1, an input side bevel gear 82 integrally rotated with the input shaft 31, a relay transmission shaft 83 capable of being freely rotated around a shaft center parallel to the second shaft center X2, an output side bevel gear 84 engaged with the input side bevel gear 82 and integrally rotated with the relay transmission shaft 83, a first flat gear 85 integrally rotated with the relay transmission shaft 83, and the second flat gear 86 engaged with the first flat gear 85 and integrally rotated with the output shaft 81 are disposed in a transmission case 87.COPYRIGHT: (C)2012,JPO&INPIT【課題】入力軸と出力軸との位置が変化する使用形態で使用される場合であっても、良好な伝動状態を得ることができるものでありながら、入力軸と出力軸との間の傾斜角度を変化させるための大掛かりな構造改良を必要としないギア式伝動装置を提供する。【解決手段】第1軸芯X1周りで回転自在な入力軸31と第1軸芯X1に対して斜めに交差する第2軸芯X2周りで回転自在な出力軸81とを連動連結し、入力軸31と一体回転する入力側のベベルギア82、第2軸芯X2と平行な軸芯周りで回転自在な中継伝動軸83、入力側のベベルギア82と噛み合い且つ中継伝動軸83と一体回転する出力側のベベルギア84、中継伝動軸83と一体回転する第1平ギア85、及び、第1平ギア85と噛み合い且つ出力軸81と一体回転する第2平ギア86の夫々が、伝動ケース87内に備えられている。【選択図】図6
