摘要： PURPOSE:To provide an instrument for measuring vibration of gear which can judge the propriety of a gear in a differential gear section based on the vibration of a propeller shaft connected to the differential gear section and can eliminate the component caused by the misalignment of the propeller shaft. CONSTITUTION:An oscillatory component associated with the rotation of a propeller shaft is calculated by analyzing the order of a detected oscillatory waveform by means of a first Fourier transformer 60 and analyzing the data of the transformer 60 by means of a cepstrum analyzer 62 and such a filter weight that can eliminate the calculated oscillatory component is calculated. The detecting signal of an oscillation detector is made to pass a filter 66 having the filter weight so as to eliminate the noise produced by the rotation of the propeller shaft. And, the detecting signals are inputted to a second Fourier transformer 68 for order analysis.

摘要： PROBLEM TO BE SOLVED: To solve problems that dirt and dust come into a case where a luggage hook is installed and that luggage is caught when it is carried in or out since the opening side of the case has an uneven surface.
SOLUTION: A luggage hook having a lid 6 turnably placed within an opening portion 5 of a case 1 and a hook body 7 placed on a back surface of the lid 6, a base end portion of the hook 7 placed turnably on the lid 6 is placed in a luggage room, on a set back surface or the like in a manner that the case 1 is embedded. Accordingly, dirt and dust are prevented from coming into the case 1 when unused and the unevenness of the luggage hook surface when unused can be kept to the minimum.

摘要： PROBLEM TO BE SOLVED: To follow the relatively large yawing motion of a vehicle to be tested. SOLUTION: A vehicle restricting apparatus 20 is constituted of the support parts 22 supported at the predetermined region of a test chamber in a rotatable manner, the restriction arms 50 for restricting a vehicle 14 to be tested, the connection parts 32 connected to the restriction arms 50 in a rotatable manner and the parallel links 42 connecting the connection parts 32 and the support parts 22. Therefore, when the vehicle 14 to be tested generates relatively large yawing motion, the connection parts 32 are rotated and displaced centering around the reference center shafts 48 on the side of the connection parts through the parallel links 42 to follow the yawing motion.

摘要： PROBLEM TO BE SOLVED: To precisely detect the force acting on the axle of a vehicle. SOLUTION: An axle force detector 10 has distortion sensors 32, 36 for detecting the distortion of the disc part 21 of a wheel 20 mounted on an axle 12, small-sized and lightweight telemeter transmitter 42, 46 for transmitting the detected distortions, a telemeter amplifier 49 for receiving distortion signals, a rotating speed sensor 50 for detecting the rotating speed V of the axle 12, and an axle force arithmetic device 60 for calculating the force F acting on the axle 12. The axle force arithmetic device 60 calculates the force acting on the axle 12 on the basis of the distortion of the disc part 21 and the rotating speed V of the axle 12. As the rotating speed sensor 50, a one provided on a vehicle as a wheel sensor used for operation control of vehicle such as ABS or TRC is used. Consequently, the unsprung mass of the vehicle can be minimized, and the force acting on the axle 12 of the vehicle can be precisely detected.

摘要： PROBLEM TO BE SOLVED: To enhance the conformability of a pressing member to a workpiece in a device which polishes the workpiece by rotating it while a polishing tape is pressed from the back to the workpiece by the pressing member. SOLUTION: A cartridge 72 holds a pressing member 96, and a swing type holding device 260 holds the pressing member 96 swingably centering on the axis Ls three-dimensionally intersecting at a right angle to the rotating axis of a workpiece 10. During polishing, the pressing member 96 is swung oscillatively with respect to the cartridge 72, and thereby the pressing member 96 is conformed to the workpiece 10.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle rolling resistance measuring device capable of measuring rolling resistance as an entire vehicle with high accuracy and ease. SOLUTION: Once a wheel 12a of a vehicle 12 is determined to be rotated at a predetermined speed by the driving drum 30 of a chassis dynamo part 18, a lift control pact in a control unit 28 lifts the vehicle 12 using a vehicle restraint part 14 to remove radial load working on the driving drum 30, and a reactive force sensor 36 placed on the driving drum 30 is used to measure reactive force working on the driving drum 30, thereby measuring rolling resistance.

摘要： PURPOSE:To shorten the working hour of a vehicle restraining device for restraining a vehicle. CONSTITUTION:The vehicle restraining device 18 is provided with a supporting section 22 which supports a coupling section 24 so that the section 24 can be moved in the vertical direction. The front end section of the coupling section 24 is provided with a ball joint 56 and a fitting section 58 equipped with a chuck 62 is provided to the joint 56. In other words, the fitting section can be freely moved not only in the vertical direction, but also in both the longitudinal and lateral directions. Therefore, when tests are started after a vehicle has been restrained by means of the device 18, the chuck 62 of the fitting section 58 is displaced in the vertical, longitudinal, and lateral directions as the vehicle makes pitching motions. Consequently, the time required by the device 18 for restraining the vehicle can be shortened because it becomes unnecessary to specify the center of gravity of the vehicle on a trial-and-error basis.
