A speed change gear includes: an internal gear member (10); an eccentric member (31, 32); an oscillating member (40, 50); a pair of first and second rotating members (60, 70); and a pin (80) that is supported at both ends by insertion holes (61, 71) of the first and second rotating members (60, 70). The insertion hole (61) and the insertion hole (71) have the same diameter. The outside diameter (Õc) of the other side end portion (83) of the pin (80) is smaller than the outside diameter (Õa) of one side end portion (81) of the pin (80) such that the one side end portion (81) is press-fitted in the corresponding insertion hole (61) and the other side end portion (83) is supported by the corresponding insertion hole (71). |
