In order to provide a functional component attaching member of which durability can be further improved because when a load is applied to a functional component while a vehicle is travelling, the load can also be borne by portions other than a wall portion opposite to a load direction, the present invention provides a rubber functional component attaching member (functional component mounting base) for fastening a functional componentto an inner surfaceof a tire, comprising a bottom surfacethat is fixed to the inner surfaceof the tire, an attaching portionhaving a recessed portionA to which a functional component-side attaching portionprovided to the functional componentis attached, and a reinforcing materialembedded in a rubber portion on an outer side of the recessed portionA.

The invention provides an apparatus, program, and method for controlling the automatic spraying of an antifreezing agent that can reduce the cost of the antifreezing agent and the impact of salt damages caused by the antifreezing agent. This is accomplished by reducing the amount of antifreezing agent to be sprayed automatically according to road surface condition and reducing the amount of the antifreezing agent left unused on completion of the spray operation by grasping in advance the total spray amount of the antifreezing agent. Thus, the antifreezing agent automatic spray control apparatus comprises a spray section setting unit for setting a spray section, a road surface condition data acquiring unit for acquiring road surface condition data, a spay condition data acquiring unit for acquiring spray condition data, a spray condition determining unit for determining the spay conditions for each of unit sections, a total spray amount advance calculating unit for calculating in advance the total spray amount of antifreezing agent to be sprayed for the spray section, a current position data acquiring unit for acquiring current position data, a unit section identifying unit for identifying a unit section corresponding to the current position, and a spray condition outputting unit for outputting the spray conditions for each of the unit sections to an antifreezing agent spraying unit.

In order to provide a functional component mounting base having high durability to an inertial force acting on a functional component when a tire engages with and disengages from the road surface and to an impact force acting on the functional component mounting base when the tire passes over bumps the functional component mounting base () is formed of a rubber material, is attached to an inner surface () of the tire to mount the functional component () on the inner surface () of the tire, and characterized by being provided with a fitting recess () into which a functional component-side attaching portion () provided on the functional component () is fitted. The fitting recess () is formed such that an opening diameter of an opening () to the fitting recess is smaller than a maximum diameter of the functional component-side attaching portion (), an inner surface (inner peripheral surface ()) of the fitting recess () is formed as a fitting surface that fits with an outer surface (outer peripheral surface ()) of the functional component-side attaching portion and a bottom of the fitting recess () is formed as raised and recessed portions (semicircular projections () and a partition recess ()) which fit with recessed and raised portions (semicircular recesses () and a partition projection) formed on the functional component-side attaching portion ().

When an electromagnetic generatorhaving a pendulum structure is mounted on an interior surface of a tire, an equivalent pendulum length l of a pendulumis adjusted such that an integral multiple of a period &#x3bb; of the pendulum, which is determined by the equivalent pendulum length l of the electromagnetic generator, is not in agreement with both of an integral multiple of a circumferential length L of the tireand a length S of a non-grounded part of the tire, which is obtained by subtracting a ground contact length C from the circumferential length L of the tire, whereby the power generation capacity of the electromagnetic generator mounted on the tire can be improved regardless of the type of the tire.

An in-wheel motor system for mounting a direct drive motor to a steering wheel comprises a first knucklewhich is connected to the non-rotary side of a geared motorby a connection member Ihaving elastic bodies and direct-moving guides for limiting movement to a vertical direction and locked in a steering direction by upper and lower suspension armsandand a second knucklewhich is connected to a steering rodand fitted with a brake unitand a wheelthrough a hub. This second knuckleis connected to the above first knucklein such a manner that it can turn on a king pin axis J in the steering direction and to the output shaft of the above geared motorby a connection shafthaving constant velocity jointsandat both ends, thereby reducing an increase in steering torque.
