摘要： A speed reducer (10) includes an external gear (40), a shaft member (50) having an eccentric member (55) for causing the external gear (40) to eccentrically oscillate, a bearing (15) disposed between the external gear (40) and the shaft member (50) and a restricting member (60). The restricting member (60) has an inner annular portion (70) and an outer portion (80). The inner annular portion (70) has an inner circumferential edge (61) located on the shaft member (50), and the outer portion (80) has an outer edge (62) with a distance from a center of the inner circumferential edge (61) to the outer edge (62) varying among different positions on the outer edge (62). The outer portion (80) restricts the bearing (15) from moving in an axial direction (D1).

摘要： A speed reducer (10) includes a carrier (30), a shaft (50) rotatably supported by the carrier (30), an external gear (40) supported by the shaft (50) and eccentrically oscillating with respect to the carrier (30) by rotation of the shaft (50), and an annular spacer (60) situated between the external gear (40) and the carrier (30). The spacer (60) rotates while contacting the external gear (40) and carrier (30).

摘要： A speed reducer (10) relating to one aspect of the present disclosure includes an outer tubular member (11), internal tooth pins (20), a plurality of oscillating gears (15A, 15B) and a carrier block (13A, 13B). The outer tubular member (11) has a plurality of pin grooves (18) on an inner circumferential surface thereof. The internal tooth pins (20) are rotatably placed in the pin grooves (18) of the outer tubular member (11). The oscillating gears (15A, 15B) have external teeth (15Aa and 15Ba) smaller in number than the grooves (18) receiving therein the internal tooth pins (20), and the oscillating gears (15A, 15B) are oscillatorily rotatable with the external teeth (15Aa and 15Ba) engaging with the internal tooth pins (20). The carrier block (13A, 13B) is cooperatively connected to the oscillating gears (15A, 15B) such that the oscillating gears (15A, 15B) are allowed to oscillatorily rotate relative to the carrier block (13A, 13B) and the oscillating gears (15A, 15B) are restricted from rotating on own axis relative to the carrier block (13A, 13B). A displacement restricting member (31), which is configured to restrict the internal tooth pins (20) from being displaced inwardly in a radial direction of the outer tubular member (11), is disposed between the outer peripheries (15e) of the oscillating gears (15A, 15B) adjacent to each other.
