Abstract: An obstacle detection device includes an ultrasonic sensor, an obstacle detector to determine presence of an obstacle of interest if an intensity of a received ultrasonic wave exceeds a threshold value, and a threshold value setter to set a short-distance detection threshold value as the threshold value for the obstacle detection in a short-distance detection area in a vicinity of the ultrasonic sensor and to set a long-distance threshold value as the threshold value for the obstacle detection in a long-distance detection area located farther from the ultrasonic sensor than the short-distance detection area, the long-distance threshold value being less than the short-distance detection threshold value. The short-distance detection area is an area where variation in sound pressure distribution of transmitted ultrasonic waves is equal to or greater than the threshold value, and the long-distance detection area includes an area where the variation of the sound pressure distribution of transmitted ultrasonic wave is smaller than the threshold value.

Abstract: A work vehicle includes a shaft supported by a cabin and having a center axis. A clutch pedal is supported by the shaft so as to be swingable about the center axis. A control cable includes an outer tube and an inner cable slidably inserted to the outer tube. The control cable is wound on a partition wall of the cabin and has flexibility. The at least one latch member is configured to latch the control cable onto the partition wall. The at least one retain member is configured to restrict the control cable from swelling within a winding region of the partition wall. The outer tube has a first longitudinal end connected to the cabin and a second longitudinal end connected to a clutch housing. The inner cable has a first longitudinal end connected to the clutch pedal and a second longitudinal end connected to the clutch lever.
