Patent attributes
A securing mechanism comprises a supporting column, an elastic piece, and a plurality of locking pieces. When the supporting column is inserted into a hole, at least one of the plurality of locking pieces is caught by or brought into pressure-contact with an outlet-side peripheral portion of the hole or an inner circumferential portion of the hole. The plurality of locking pieces form a plurality of arrays extending in a projection direction of the supporting column. The locking pieces included in each array of the plurality of arrays are aligned spaced apart from one another in the projection direction of the supporting column. The plurality of arrays comprise a first array and a second array; positions of the locking pieces in the first array are displaced from positions of the corresponding locking pieces in the second array in the projection direction of the supporting column.
