PROBLEM TO BE SOLVED: To provide a transmission capable of restraining grease leakage without using an oil seal. SOLUTION: This transmission includes freely rotatable first connecting part 1 and second connecting part 2, a gear-shift part 3 having a plurality of second planetary gears 36, and a casing 4 for storing them, wherein grease is injected into the gear-shift part 3. The second connecting part 2 includes an input part 21 rotatably supported by the casing 4 via a second bearing 9, and a sun gear 38 engaging with the second planetary gears 36. A first regulating wall part 45 and a second regulating wall part 51 overhanging toward the input part 21 from the casing 4 over the whole periphery, are mutually separately arranged in the rotary axis direction between the second sun gear 38 and the second bearing 9.
