Abstract
A load detector is constructed so as to stabilize an output voltage responding to an input load. The load detector includes a magnetostrictive sensor which includes a hollow case, a coil housed in the case, and a rod-like magnetic member located at an axial center of the coil, magnetized by an electric current flowing through the coil and receiving a load at an end thereof. The load detector further includes a pin which has a contact surface for applying the load onto the end of the magnetic member and is disposed axially inline with the magnetic member, and a bearing collar for reducing displacement of the pin with respect to the magnetic member. The magnetostrictive sensor and the pin are fitted, facing each other, into the bearing collar. The load detector is utilized suitably for transport equipment such as a water vehicle or electric bicycle.
