Abstract: A calculating device of the stiffness measurement device pressurizes an object to be measured with a predetermined pressure and the stiffness of the object to be measured in the squeal frequency band is calculated based on an inclination of a stress-displacement performance curve immediately after a start of depressurization after the pressurization. According to this device, there is no need to oscillate the object with a high frequency band and there is no need to enhance the stiffness of the housing of the measurement device, which leads to a downsizing of the device. Further, there is no need for measuring of acceleration speed of the object to be measured and accelerator can be eliminated to reduce the cost of the stiffness measurement device.

Abstract: A brake temperature detection device: acquires a kinetic-energy based temperature rise, which is an increase in an amount of brake heat that occurs when kinetic energy generated in a running vehicle is converted into thermal energy by braking; acquires a braking-energy based temperature rise, which is an increase in an amount of brake heat that is calculated from an amount of work done when a brake's friction material is pressed against a friction target material; determines state of slope of a road surface on which the vehicle is running; and detects a brake temperature in accordance with an increase in an amount of brake heat generated in braking. The brake temperature detection device selects, based on the state of slope, either the kinetic-energy based temperature rise or the braking-energy based temperature rise as the increase in the amount of brake heat generated in braking and achieves brake temperature detection.

Abstract: A housing projection is formed at a bottom of a second reservoir hole in a housing. According to this, a tip side in a press-fitting direction of a sleeve tends to deform inwardly in a radial direction and escape from the housing in a process of press-fitting the sleeve 88 into the second reservoir hole, since an inner slant part of the tip side of the sleeve contacts to a contacting surface of the housing projection, deformation of the tip side of the sleeve 88 is suppressed.
