Abstract: When a verification result by a verifier is a success, an electronic control unit activates a rewriting target program stored in a second storage, and transmits a verification result reply signal that indicates that the verification result is a success to a relay apparatus. When a verification result by the verifier is a failure, the electronic control unit activates a communication control program stored in a first storage, and transmits a verification result reply signal that indicates that the verification result is a failure to the relay apparatus. Upon receiving the verification result reply signal that indicates that the verification result is a success, the relay apparatus identifies a correct rewriting operation with the rewriting target program. In contrast, upon receiving the verification result reply signal that indicates that the verification result is a failure, the relay apparatus identifies an incorrect rewriting operation with the rewriting target program.

The linear guide apparatus includes a retainer for retaining plural cylindrical rollers rotatably in a rolling element rolling passage. The retainer includes an opening portion and accommodates for retention of the plural cylindrical rollers in the opening portion. The retainer also includes an endless seal unit surrounding the opening portion. The seal unit includes an inward facing lip inclining toward the inner side of the opening portion and extending toward the guide rail to be in sliding contact with the guide rail. The inward facing lip is formed continuously all around the seal unit. The seal unit includes an outward facing lip inclining toward the outer side of the opening portion and extending toward the guide rail to be in sliding contact with the guide rail, in addition to the inward facing lip.

Abstract: A side seal attached to each of both ends of a slider of a linear guide in a sliding direction and sliding in contact with a guide rail includes: a seal main body formed by shaping an elastic material using a mold and sliding in contact with the guide rail; and a holder for housing and holding the seal main body. A gate burr housing for an elastic-material gate burr of the seal main body is formed in a seal main body holder housing. This eliminates the need of complete cutting or elimination of the elastic-material gate burr of the seal main body, and improves assembling performance. The gate burr housing is formed at a front or rear side of the seal main body housing of the holder, and the elastic-material gate burr of the seal main body is formed at a corresponding portion to the gate burr housing.
