Abstract: A ventilation apparatus includes a motor, a fan, a housing, and a ring. A projection protrudes from one of an outer peripheral surface of a peripheral wall part of the housing and an inner peripheral surface of the ring, whereas an engagement wall and a guide wall are provided on the other of the outer peripheral surface of the peripheral wall part of the housing and the inner peripheral surface of the ring. The guide wall has a guide surface configured to guide the ring rearward relative to the housing and to guide the projection to an engagement position at which the projection is abuttable on an engagement surface of the engagement wall. In a direction in which the projection moves away from the guide surface in a front-rear direction, an open space extends from the guide surface to an area that corresponds to an end of the second surface.

Abstract: A garment in one aspect of the present disclosure includes an outer fabric and a lining fabric. The outer fabric forms a front body part and a back body part. The front body part includes a first opening to be situated in a center portion of the front body part in a width direction of the garment when the garment is worn over a wearer. The first opening extends in a length direction of the garment. The lining fabric is attached to the outer fabric so as to form an internal space between the lining fabric and the outer fabric. The internal space is formed (i) to accommodate a fan in the internal space and (ii) to let an airflow generated by the fan pass through the internal space.

Abstract: A power tool for driving an accessary removably held between first and second clamp parts includes a first shaft having the first clamp part, a second shaft for moving the second clamp part, a holding member movable relative to the second shaft, a moving member for moving the holding member, and a biasing member for biasing the moving member. The second shaft is disposed inside the first shaft. The holding member enables the second clamp part and the first clamp part to hold the tool accessary therebetween in a first position, and disables the second clamp part and the first clamp part from holding the tool accessary in a second position. The moving member moves the holding member from the first position to the second position, and the biasing member biases the moving member when the holding member is located in the second position.

Abstract: A voltage control device in one aspect of the present disclosure includes an appliance connector, a voltage output circuit, a manual switch, and a controller. The voltage output circuit outputs an operating voltage based on a direct voltage received from a direct-current power source. In response to a first electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to fix the operating voltage. In response to a second electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to vary the operating voltage in accordance with a manual operation applied to the manual switch.

Abstract: A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.
