Provided is an internally engaged planetary gear device with a simplified structure. The internally toothed gear (2) has an annular gear body (22), and a plurality of pins (23) that are held in a rotatable state on the inner peripheral surface of the gear body (22) and constitute internal teeth (21). The planetary gear (3) has outer teeth (31) that partially mesh with the inner teeth (21). The plurality of inner pins (4) revolve in a plurality of inner pin holes (32) formed in the planetary gear (3) and rotate relative to the gear body (22) in a state of being inserted into the inner pin holes (32). The first bearing member (6) and the second bearing member (7) rotatably support the plurality of inner pins (4) on the gear body (22) at two positions in the direction of the rotating shaft (Ax1). The first bearing member (6) has a first inner ring (61), a first outer ring (62), and a plurality of bearing pins (63). The plurality of inner pins (4) are positioned on the inside of the second bearing member (7) when viewed from one side in the direction of the rotating shaft (Ax1). The invention further discloses a wheel device comprising the internal meshing planetary gear device and a vehicle.

    一种容易实现结构的简化的内啮合行星齿轮装置。内齿齿轮(2)具有环状的齿轮主体(22)、以能够自转的状态保持于齿轮主体(22)的内周面并构成内齿(21)的多个销(23)。行星齿轮(3)具有与内齿(21)局部地啮合的外齿(31)。多个内销(4)在分别插入于在行星齿轮(3)形成的多个内销孔(32)的状态下,在内销孔(32)内公转并相对于齿轮主体(22)相对旋转。第一轴承构件(6)及第二轴承构件(7)在旋转轴(Ax1)方向的两个部位将多个内销(4)能够旋转地支承于齿轮主体(22)。第一轴承构件(6)具有第一内圈(61)、第一外圈(62)及多个轴承销(63)。多个内销(4)在从旋转轴(Ax1)方向的一侧观察下位于第二轴承构件(7)的内侧。还公开了一种包括内啮合行星齿轮装置的车轮装置和车辆。
