SEAL DEVICE AND GEAR TRANSMISSION DEVICE

摘要

A lubricant oil seal device (50) having an oil seal (60) for preventing lubricant oil from leaking, and a foreign object capturing member (70) provided further inward than the oil seal. The foreign object capturing member has a holder (75) fixed to a device body or the oil seal, and a filter material (73) held by the holder and permeable to the lubricant oil. The filter material forms a distal end sliding part (71) for the foreign object capturing member kept in sliding contact with the device body or the oil seal in association with the relative rotation of a case and a carrier.
