Abstract
[Problem] A power transmission unit that improves quietness of a gear mechanism and prevents a size of the unit from increasing when a brake rotor is installed around an input shaft of the gear mechanism. [Solution] The power transmission unit includes an electric driving motor with a motor shaft, a gear mechanism, and an output shaft, which are accommodated in a transmission housing, wherein the power of the motor shaft is transmitted to the output shaft via the gear mechanism. The gear mechanism has a gear shaft rotatably supported on the transmission housing and a first helical gear provided on the gear shaft. The power transmission unit further includes a connecting member provided with a tubular portion fitted to the motor shaft and the gear shaft so as to allow the motor shaft and the gear shaft to synchronously rotate. The connecting member is integrally provided with a brake rotor on the outer periphery thereof.
