A metal gasket used in an engine with a chain case, using a foam-rubber seal member shaped to withstand in practical use and having excellent long-lasting reliability and excellent durability. A total constitutive plate of the metal gasket is extended along the chain case to form an extended part. This extended part has a chain case hole. The foam-rubber seal member seals a chain case opening and a three-surface joining portion defined by the chain case, a cylinder block and a cylinder head. The foam-rubber seal member is a separate and distinct member and is a sheet-like and loop-like combination of layers of foam rubber and a metal core plate interposed between these foam rubber layers.

A vehicle playing apparatus on which a player himself or herself operates a simulation vehicle. The apparatus comprises a vehicle moving variably on which a player rides, driving mechanism 33, 70 for driving the vehicle detection member 25, 26, 35 for detecting a state of the vehicle, operation member 42, 46 provided on the vehicle, and controller 80 for controlling the drive mechanism based on a detection signal inputted from the detection member and an operation signal inputted from the operation member. The controller judges the state of the vehicle in accordance with the detection signal, indication and timing of the operation signal in view of the state, of vehicle to output an instruction signal to the drive mechanism.

An apparatus for protecting against overvoltage includes a semiconductor switching element and a trigger element. The semiconductor switching element is formed of a PNPN junction including a plurality of PN junctions and the trigger element has a characteristic similar to that of a PN junction Zener diode. The apparatus for protecting against overvoltage is normally nonconductive; however, once an overvoltage not lower than a defined level is applied, the trigger element attains a state so as to have a gate current flow from a gate electrode thereof to the semiconductor switching element. In response to this, the semiconductor switching element causes a so-called thyristor phenomenon, thereby protecting a load connected in parallel to the apparatus for protecting against overvoltage, i.e., an object to be protected, from being provided with the overvoltage.

A disc brake assembly includes a stationary support member mounted on a vehicle body structure and having at least one support pin fixed thereto, a caliper member slidably supported on the support pin to be movable in an axial direction, and a tubular elastic boot arranged in surrounding relationship with the support pin to enclose a sliding portion on the same. To protect the elastic boot, a cylindrical elastic protector is arranged to contain therein the elastic boot, the elastic protector having one end coupled with a member such as a washer or a cup-shaped member fixed to the outer end of the support pin and the other end pressed into contact with an end face of the support portion of the caliper member.

An antirattle spring for a disc brake is represented as being entirely disposed outside of a clearance between one of a plurality of edges of pad assemblies and a stationary member anchoring against the one edge. Consequently, the antirattle spring is freed from any restraint as would otherwise be imposed upon a designer of a more complicated and smaller sized configuration of the spring, and is therefore more likely to retain its resiliency than are prior art antirattle springs. The antirattle spring has one end thereof bolted to the stationary member and the other end thereof engaging one of the plurality of edges with a required elastic energy stored within the middle portion of the spring.
