An outdoor unit for an air-conditioning apparatus includes a body frame having, in a side face, an air inlet from which outside air is suctioned, the body frame including a hanger-receiving portion in an upper part, the hanger-receiving portion including a beam-like supporting part; an outdoor heat exchanger provided inside the body frame and extending along the air inlet; a hanging portion engaging with the outdoor heat exchanger; and a connecting element connecting the hanger-receiving portion and the hanging portion to each other. The outdoor heat exchanger is supported by the hanger-receiving portion through the hanging portion and the connecting element.

A refrigerant pipe is provided to be capable of preventing a change in a length by which the refrigerant pipe is inserted after the refrigerant pipe is inserted. The refrigerant pipe includes a heat-exchanger-side pipe having a pipe component insertion flare formed at an end portion of the heat-exchanger-side pipe and at least one protrusion formed on an inner peripheral portion of the pipe component insertion flare, and a pipe component having a smaller outer diameter than an inner diameter of the pipe component insertion flare. A height of the at least one protrusion is greater than a dimension of a clearance defined on the basis of a difference between the inner diameter of the pipe component insertion flare and the outer diameter of the pipe component. The pipe component is inserted into the pipe component insertion flare, and the pipe component has a groove formed by the at least one protrusion.

A toilet seat/toilet lid device includes a toilet seat and a toilet lid that are provided to be pivotable with respect to a toilet between an erected state and a laid state; a toilet seat drive device that is configured to cause the toilet seat to pivot; a toilet seat pivot shaft that extends from the toilet seat drive device to one side of the toilet in a width direction, pivotably supports the toilet seat and supports the toilet lid; a toilet lid drive device that is configured to cause the toilet lid to pivot; and a toilet lid pivot shaft that extends from the toilet lid drive device to the other side of the toilet in the width direction, pivotably supports the toilet lid, and supports the toilet seat.

Toilet seat/toilet lid device

Provided is a method of manufacturing a toilet seat that is formed by joining together a seat front member and a seat rear member. The method includes a cutting step of forming a processed surface of a joint part between the seat front member and the seat rear member by cutting the joint part between the seat front member and the seat rear member with a cutting tool having a curved cutting blade part such that the shape of the processed surface is formed in a curved shape in which the seat rear member side thereof protrudes outward in a cross section perpendicular to the direction in which the joint part extends.

Provided is an outdoor unit for an air-conditioning apparatus, including a heat exchanger having heat exchanger cores stacked in a plurality of stages in a vertical direction of the outdoor unit. Each of the heat exchanger cores includes: a plurality of fins arranged in parallel to each other at intervals therebetween; and heat transfer tubes provided to extend through the fins, through which refrigerant is caused to flow. Each of the fins of the heat exchanger includes a deformable portion configured to be deformable by impacts applied to the deformable portion, which is formed at a position where the fins of the upper one of the heat exchanger cores from among the vertically-adjacent heat exchanger cores comes into contact with the fins of the lower one of the heat exchanger cores from among the vertically-adjacent heat exchanger cores.
