Abstract: A dust collector includes a tank, a main body, a suction fan, a flexible pre-filter, and a main filter. The tank includes a suction opening. The main body is fixed to an upper portion of the tank. The suction fan is disposed at the main body. The suction fan is rotated by a motor. The flexible pre-filter is housed in the tank at a lower side of the main body. The pre-filter is positioned at an upstream side of external air suctioned from the suction opening. The main filter is positioned at a downstream side of the pre-filter. The main filter has a plate shape disposed laterally.

Abstract: An upright vacuum cleaner includes a main-body part (10) having a dust-collection chamber (14) fluidly connected to a motor chamber (13) via a coupling pipe (15). A fan (13f) and a motor (13m) are housed in the motor chamber. A cleaner head (20) is pivotably and fluidly connected to the main-body part and suctions air through a suction opening (23) when a suction force is generated by the fan and the motor in the motor chamber. A straight suction passageway (24) extends through a central portion of the interior of the cleaner head in plan view. One or more batteries (50) is/are disposed within the cleaner head spaced apart (outward) from the suction passageway in the plan view.

Abstract: A power tool includes a motor, a housing, a battery mounting part, and a battery protection part. The battery mounting part is provided to the housing on an opposite side from a working axis across the motor in an extending direction of a rotation axis of the motor. The battery mounting part is configured such that one end portion of at least one battery is mounted to the battery mounting part and an opposite end portion of the at least one battery in the extending direction of the rotation axis is exposed from the housing. The battery protection part is provided to an outer surface portion of the housing and configured to protect at least one corner region of the opposite end portion of the at least one battery against external force when the one end portion is mounted to the battery mounting part.
