Abstract: A carrier device includes a coupling mechanism for coupling an automatic controlled vehicle to a carriage. The coupling mechanism includes a first shaft member, a second shaft member and a third shaft member. The coupling mechanism includes a guide rail section, a lock member, and an actuator that moves the lock member. The guide rail section is provided on the automatic controlled vehicle. When the lock member moves from the first position to the second position, the lock member enters between the first shaft member and the second shaft member. The third shaft member fits with the fitting portion of the lock member.

Abstract: Provided is a flexible member that can exhibit excellent load resistance and flexibility while achieving a reduction in size. This flexible member includes: a main body part which has multiple wave washers stacked in an axial direction and joined to each other, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers; and a linking member that is elastically deformable, the linking member being provided at an end part of the main body part and being linked to other member. A deformation amount of the linking member is smaller than a deformation amount of the wave washer, when the main body part is bent.

Abstract: According to an embodiment, a coil spring includes a wire rod having an end and the other end. The wire rod of the coil spring includes, with regard to a section of the wire rod, a round section potion of an effective spring part, a square section portion in which the section is substantially square, and a taper portion. The square section portion includes an end turn part. A length of each side of the section of the square section portion is less than or equal to a square root of ½ multiplied by a diameter of the wire rod of the round section portion. In the taper portion, from the round section portion to the square section portion, the section changes from a round shape to substantially a square shape, and a sectional area is decreased.

Abstract: A contact probe is conductive and capable of expanding/contracting along an axial line direction. The contact probe includes: a first contact member configured to contact one contact target; a second contact member configured to contact another contact target, and to house at least a portion of the first contact member; and a spring member configured to couple the first contact member and the second contact member in a manner capable of expansion/contraction with both end parts of the spring member. The spring member is wound in a helical shape, and at least a diameter of an outer circumference in one of the end parts held by the second contact member is larger than diameters of other portions. A diameter of an inner circumference of an end part of the second contact member on a side housing the first contact member is equal to or larger than a maximum diameter of the first contact member.

Abstract: An adhesive reactive to ultraviolet rays is applied to an actuator mounting portion of a suspension. An electrical conducting material is applied to a conductor and the like of the actuator mounting portion. When the adhesive is irradiated with ultraviolet rays, the viscosity of the adhesive is increased. A piezoelectric element is placed on the adhesive the viscosity of which is increased. Thereafter, the adhesive and the electrical conducting material are heated, whereby the adhesive and the electrical conducting material are cured.
