[2] Rotation transmission mechanism (29) according to claim 1, wherein the shaft element (33) rotatably supports at least one of the first intermediate gear (31) and the second intermediate gear (32), the preloading element (34) is arranged between the first intermediate gear (31) and the second intermediate gear (32) in the axial direction in order to preload the first intermediate gear (31) and the second intermediate gear (32) in a direction in which the first intermediate gear (31) and the second intermediate gear (32) are axially separated from each other, and the first intermediate gear (31) and the second intermediate gear (32) are restricted from movement to separate from each other in the axial direction. [3] Rotation transmission mechanism (29) according to claim 2, wherein the first intermediate gear (31) further includes a through hole (31c) through which the shaft element (33) penetrates in the axial direction, the first gear body (31a) has teeth on an outer peripheral surface thereof, the second intermediate gear (32) is rotatably supported by the shaft member (33), the second gear body (32a) has a diameter larger than an outer diameter of the through hole (31c) of the first intermediate gear (31), and has teeth on an outer peripheral surface of the second intermediate gear (32), and the small diameter portion (32b) extends from a side surface of the second gear body (32a) to the first intermediate gear (31) in the axial direction, and the biasing member (34) is an elastically deformable, annular elastic member arranged on an outer periphery of the small diameter portion (32b) of the second intermediate gear (32). [4] Rotation transmission mechanism (29) according to claim 3, wherein the through hole (31c) of the first intermediate gear (31) is capable of receiving a portion of the second intermediate gear (32), and the small diameter portion (32b) of the second intermediate gear (32) partially comes into contact with an inner peripheral portion of the through hole (31c) to support the first intermediate gear (31). [5] A rotation transmission mechanism (29) according to any one of claims 3 and 4, wherein the small diameter portion (32b) of the second intermediate gear (32) includes, at an outer periphery thereof, an engaging portion (32d) which engages with the first intermediate gear (31). [6] A rotation transmission mechanism (29) according to any one of claims 2 to 5, wherein at least one of the first intermediate gear (31) and the second intermediate gear (32) is a spur gear. [7] Rotation transmission mechanism (29) according to one of claims 2 to 6, wherein the toothings of the first intermediate gear (31) have a different shape than those of the toothings of the second intermediate gear (32).
