POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To enlarge a degree of freedom of design by restraining a confliction over a space with other parts.

SOLUTION: There is provided a power transmission device 1 which houses and supports in a distribution case 5 an orthogonal gear assembly comprising a ring gear and a pinion gear which engage perpendicularly with each other. In the power transmission device 1, the distribution case 5 is divided into a first case section 65 and a second case section 67 by a dividing surface 63 along a rotary axial center of the ring gear. Besides, the divided surfaces 63 are allowed to mate with each other to couple the first and second case sections 65, 67 by bolts 69.
