摘要： An attachment coupler includes a first arm and a second arm, each including a U-shaped portion, and upper portions of the first and second arms being swingably connected by a swing shaft, and an expansion-contraction tool which opens and closes the first and second arms around the swing shaft as a fulcrum. A locking member provided with a cam and a hook provided with a cam follower are rotatably provided on the second arm. A state in which a free end of the hook is removed from an opening of the U-shaped portion is maintained by engagement of the cam and the cam follower during contraction of the expansion-contraction tool. The cam follower is driven by the cam along with rotation of the locking member during expansion of the expansion-contraction tool, thereby causing the free end of the hook to advance toward the opening of the U-shaped portion.

摘要： To lighten the weight of an electromagnetic actuator and a valve-open-close mechanism by forming the stems from a lighter material than conventional. A pair of electromagnets formed of stators and coils are opposed to each other with a gap therebetween. An armature is disposed in the gap so as to be reciprocable between one electromagnet and the other electromagnet by the electromagnets. A first stem for transmitting the movement of the armature from one electromagnet toward the other electromagnet to a valve of the internal combustion engine is inserted in a guide hole formed in the stator of one electromagnet. The first stem is formed of a lighter material than the armature to lighten the weight of the electromagnetic actuator and a valve-open-close mechanism of an internal combustion engine.
