Abstract: A work vehicle state detection system includes: a travel state detector provided in a work vehicle having a rotating machine and detecting a travel state of the work vehicle; a vibration sensor in the rotating machine; a travel state data acquisition unit acquiring travel state data indicating the travel state; a condition satisfaction determination unit determining whether the travel state satisfies a condition; a vibration detection data acquisition unit acquiring vibration detection data indicating a detection value of the vibration sensor when the travel state satisfies the condition; a normal vibration data storage storing normal vibration data indicating a detection value of the vibration sensor when the rotating machine is normal and the travel state satisfies the condition; and an analysis unit that, based on the vibration detection data and the normal vibration data, analyzes a state of the rotating machine when the vibration detection data is acquired.

Abstract: A mechanical device includes a housing, a transparent spacer member, a magnet, and an image capturing device. The housing has an internal space in which a machine component immersed in oil is housed. The spacer member is disposed in an opening of the housing. The magnet is supported by the spacer member. The image capturing device captures the internal space of the housing via the spacer member.
