A seat slide device for vehicles includes a lower rail, an upper rail, a lock mechanism, a spring member, and an unlocking handle. The upper rail is supported in a slidable manner by the lower rail. The lock mechanism is provided within the upper rail and restricts the movement of the upper rail relative to the lower rail. The spring member is provided within the upper rail. The unlocking handle is operated against the pressing force of the spring member to remove restrictions on the movement of the upper rail imposed by the lock mechanism. The upper rail has inner walls and outer walls. The inner walls have engagement holes formed through the inner walls in the width direction. The spring member has engagement sections inserted through and engaged with the engagement holes. The engagement sections face the outer walls in the width direction.

A seat apparatus includes a lower arm including one of an internal gear and an external gear, an upper arm including the other of the internal gear and the external gear, a lock member restricting and allowing a movement of a seat; a lever being rotatably connected to the lower arm, the lever being linked with an operation of the lock member to restrict the movement; and a transmission portion disposed between the lower arm and the upper arm, the transmission portion transmitting a rotation of the upper arm which corresponds to a forward inclination of a seatback to the lever by absorbing an eccentricity of the internal gear and the external gear.

The present invention provides a method of manufacturing a heat exchanger tube in which a tube for a heat exchanger formed by brazing is manufactured using a sheet material, wherein a filler metal melted during brazing can be prevented from entering an opening formed in an opposing portion or a parallel portion formed when bending a sheet material into a tube shape or an opening facing toward the outside of the tube. The opposing portion, the parallel portion, or the opening facing toward the outside of the tube is sealed. As the sealing means, friction welding is preferable.

Method of manufacturing heat exchanger tube and heat exchanger

In a method of applying a brazing material to braze a joining portion between a first member and a second member, a relationship between an amount of the brazing material and an expanding dimension of the brazing material is determined. Then, a position to apply the brazing material or a necessary amount of the brazing material is decided based on the relationship. After the first member and the second member are joined, the brazing material is applied. The position is defined by a distance from the joining portion. The distance is set smaller than one-half the expanding dimension of the brazing material on an applying surface.
