<p>Among opposing plates (2, 3) constituting a carrier body (1), one plate (2) is directly connected to an external periphery of a shaft part (5) in the vicinity of a shaft end thereof, and the other plate (3) is connected to the shaft part (5) via support columns (4) extending from a shaft end (5a) at an interconnection part between the plate (2) and the vicinity of the shaft end (shaft part (5)). Four support columns (4) forming a set are disposed at equal intervals in the circumferential direction in an external peripheral part of the plate (3), and are integrally connected to the plate (3). The support columns (4) also extend at an angle so as to converge toward the shaft end (5a), and ultimately merge and integrate with a shared annular body (4a). The annular body (4a) is fitted on the shaft end (5a) and connected to the shaft end (5a). Planetary pinions (not illustrated) are supported on pinion shafts (not illustrated) inserted in through-holes (2a, 3a) in the plates (2, 3).</p> |
