Abstract:
A collision detecting apparatus comprising:a moving member moving when subjected to an impact of more than a given level arising from a collision with another object; and a first and a second contact member which are disposed on a mount base and extend with a given gap therebetween, said first contact member being brought by said moving member into contact with said second contact member to produce an electrical signal indicative thereof when said moving member undergoes the impact of more than the given level, at least one of said first and second contact members being made of a leaf spring which has a length including a base portion secured on the mount base and a contact portion for establishing contact with an opposing contact portion of the other of said first and second contact members, the base portion being larger in width than the contact portion; wherein surfaces of the contact portions of the first and second contact members are slitless to increase mechanical strength thereof and to decrease a propensity of the first and second contact members to vibrate and cause contact chatter.
