Abstract
A detection element detects at least compression load. A first member has a surface provided with the detection element. A preload adjusting member is substantially in a column shape and has a tip end configured to apply pressure to the detection element. The first member and the second member are connected with each other and configured to transmit load to the detection element. The second member has a fitted portion, which has an inner circumferential periphery being press-fitted with the preload adjusting member. The second member causes elastic deformation in response to adjustment of press-fitting of the preload adjusting member and causes change in preload applied to the detection element.
