Title
(EN) GEAR BOX
(JA) ギヤボックス
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a gear box that does not need assembling efforts.

SOLUTION: A gear box includes: a driving shaft 51 including a worm 53; a driven shaft 55 which is disposed so as to intersect with the driving shaft 51 and includes a worm wheel 57 meshing with the worm 53; a pair of first cases 59, 61 which are disposed so as to place the worm 53 pinched in the axial direction and on which holes 59a, 61a for inserting the driving shaft 51 are formed; a pair of second cases 63, 65 which are disposed so as to place the worm wheel 57 pinched in the axial direction and on which holes 63a, 65a for inserting the driven shaft 55 are formed; and pushing mechanisms 63b, 63c, 65b, 65c which push the pair of first cases 59, 61 to each other when the second cases 63, 65 are pushed toward the first cases 59, 61.
