Abstract: An electromagnetic relay has a base, an electromagnet unit mounted on the base, and having a coil, a movable contact plate having a movable contact mounted on a distal end thereof, and a first stationary contact terminal and a second stationary contact terminal. The movable contact plate is moved by electrically energizing and deenergizing the coil of the electromagnet unit to cause the movable contact to make and break contacts with the first stationary contact terminal and the second stationary contact terminal alternately. The first stationary contact terminal and the second stationary contact terminal are implanted vertically in the base. The first stationary contact terminal supports a stationary contact. The second stationary contact terminal supports an insulating member mounted thereon.

Abstract: The present invention prevents a lock pin from coming out of a lock hole even if a fuel lid locked in a bolted manner by intrusion of the lock pin into the lock hole is pushed toward a vehicle body. A second lock hole is formed in an inner peripheral wall of the lock hole and a protruding portion formed on the lock pin is engaged in the second lock hole when the fuel lid is pushed toward the vehicle body.

Abstract: An electromagnetic relay has a solenoid formed from a wound coil, a movable contact-point block having a movable iron core, an insulation holder integrated with the upper end portion of the movable iron core and a movable contact piece which is biased toward and supported by the insulation holder through a contact pressing spring, and a fixed iron core fitted in a through hole in a yoke.

Abstract: The present invention is to provide a base material for a laminate having a high strength, reduced thickness, and light weight. In the present invention, a base material is prepared by incorporating a thermosetting resin binder into a non-woven fabric of para-aramid fibers prepared by a wet type paper making, and then heating a plurality of the resultant non-woven fabric sheets under pressure. The non-woven fabric sheet comprises 95 to 70 mass % of the para-aramid fibers and 5 to 30 mass % of the thermosetting resin binder.
