Abstract:
1. A drive force distributing apparatus including a first roller rotatable jointly with a main drive wheel system and a second roller rotatable jointly with a subordinate drive wheel system in which a drive force distribution to the subordinate drive wheel system is enabled by pressing the first roller and the second roller against each other in a drive force transmittable way, wherein control of the drive force distribution between the main drive wheel system and the subordinate drive wheel system is performed by turning one of the first and second rollers to thereby adjust a radial pressing force of the first and second rollers, the drive force distribution apparatus comprising: a structural body that suppresses turning of the one of the first and second rollers at a predetermined position; and a reference position setting mechanism that turns one of the first and second rollers in one direction, detects a position at which the turn is suppressed by the structural body, and sets a reference position based on the detected position, wherein a turning amount of the one of the first and second rollers is detected with respect to the reference position set by the reference position setting mechanism and the control of drive force distributing is performed based on the detected turning amount.
