A steering device for use in a toy car includes an output member having a pair of deformable arms and coupled to a servo, and an input member having side surfaces to be in contact with the free ends of the arms. When the great amount of reaction force from the wheel is applied through the input member to the arm of the output member, this force will be absorbed by the arm due to its elastic deformation so that the damage of the servo is nothing.

A shock absorber for use in toys comprising a rod for supporting a wheel, a retainer slidably along the rod, and a spring interposed between the lower section of the rod and the retainer which forces the retainer upwardly. These members can be pre-assembled as unit kit. When the shock absorber is mounted on a chassis member, the retainer is depressed downwardly against the biasing force of the spring and the rod is inserted into a bore formed on a chassis member through a opening side groove thereon. After that, the retainer is held in a recess on the bottom of the chassis member so that the rod is reciprocable along the retainer and the bore of the chassis member to absorb the vibration or shock from the wheel.

An ultrasonic sealing apparatus is disclosed wherein a pair of sheet-like members a bottom portion of a tubular member is fuse-bonded together by frictional heat generated by ultrasonic vibration. The apparatus includes horn (1) and anvil (2) means interposed with members to be fuse-bonded together. The horn and anvil provide contact surfaces (3) in contact with the members to be fused. Each of the contact surfaces is formed with a plurality of grooves (4) to provide a plurality of protrusions (5). Each of the protrusions has a flat upper surface and slanted side surfaces (6), so that the protrusion has a trapezodial cross-section. The horn means applies ultrasonic vibration to the fuse-bonding surfaces of the members to be fused in a direction oblique or parallel therewith in association with the anvil means.
