Abstract: A high-frequency coil component includes a sealing portion containing a resin and a plurality of hollow particles, and a coil portion composed of a wound conductive wire. The coil portion is sealed in the sealing portion. The resin includes a low-dielectric resin having a relative permittivity ?r1 of 2.00 or more and less than 3.00 at 23±2° C. A mass of the resin is represented by Mr. A total mass of the plurality of hollow particles is represented by Mp. Mr/(Mr+Mp) is 25% or more and 85% or less.

Abstract: A pedal device includes: a pedal that is depressed by a driver; and a reaction force generation mechanism. The reaction force generation mechanism generates a reaction force against a depression force applied from the driver to the pedal. The reaction force generation mechanism includes at least one resilient member, a first holder and a second holder. The first holder contacts the at least one resilient member from one side where the pedal is placed in one direction. The second holder contacts the at least one resilient member from another side that is opposite to the one side. One holder among the first holder and the second holder includes an outer guide portion, and another holder among the first holder and the second holder includes an inner guide portion that is fitted into the outer guide portion and is movable relative to the outer guide portion in the one direction.

Abstract: A pedal device includes a pedal, a connecting rod, a reaction force generating mechanism, a housing having a housing hole for allowing the connecting rod to pass therethrough when the pedal is stepped on by an operator, and a cover member. The cover member includes a first connecting portion and a covering portion. The first connecting portion is connected to a housing end portion of the housing forming a housing hole. The covering portion is arranged at a position between the first connecting portion and a back surface of the pedal and is connected to the first connecting portion to cover the housing hole.

Abstract: A toothbrush includes a head portion (10) having a bristle tufting surface; a grip portion (30) disposed on a rear end side from the head portion; a neck portion (20) disposed between the bristle tufting surface (11) and the grip portion; and a sensing portion (70) for sensing that an external force in a first direction orthogonal to the bristle tufting surface exceeds a threshold value. A reversal portion (80) connects a first region and a second region, and snaps, buckles, and reverses as the head portion is displaced on a rear surface side due to the external force exceeding the threshold value. An elastic deformation portion (90) connects the first region and the second region, and elastically deforms at least up to the external force at which the reversal portion snaps, buckles, and reverses.
